.05). This case report describes the effect of complete denture abstention and subsequent rehabilitation with mandibular implant-supported overdentures (IOD) on masseter muscle thickness (MMT) in a 97-year-old patient. We are now at the center of another grand transformation… One of the principal technologies of this new mode of production and social organization is the Internet. Purpose: Implant treatment using osseointegrated implants has been performed for more than 40 years, but limited knowledge is available on how treatment outcomes have changed over time. The highest stress reduction ratio under all loading conditions was obtained using the FRC1 model. One major use of ISO 4 is to abbreviate the names of scientific journals. Furthermore we use Google Analytics to create anonymized statistical reports of the usage which creates Cookies too. After 5 and 10 years a cumulative survival rate of 97.7% and 93.5%, respectively, and a cumulative success rate of 97.7% and 92.2%, respectively, was recorded. No differences in survival rate were found for resin-bonded fixed partial dentures in the maxillae or mandible, or in the anterior and posterior regions. This case series study evaluated the clinical outcomes of cantilevered veneer-retained fixed partial dentures (VRFPDs) fabricated with IPS e.max Press for single-tooth replacement in the anterior arch. Results: Nine FPDs were lost because of extraction of an abutment tooth, and 1 FPD was removed for esthetic reasons. When the spherical alloy was air abraded using 60-microns aluminum oxide prior to cementation of a Rexillium rod using Panavia, the bond strength was not significantly different from the previously reported bond strengths of Panavia to etched enamel. The patients were evaluated at baseline and annually from October 2005 to July 2011 for the integrity of the VRFPDs, proximal contacts, occulsal relationships, pulp vitality, and tooth mobility. Successful sinus membrane water balloon lifting procedures were performed in 26 cases; two procedures were aborted due to sinus membrane perforation. Those statements are on file at the editorial office. International Journal of Periodontics & Restorative Dentistry. Dresden, 23-26 May 2002. For the last several years, this procedure has also been used for single-tooth replacement following loss of teeth for traumatic, periodontal, and carious lesions. The clinical performance of 325 resin-bonded fixed partial dentures (RBFPD) placed between 1984 and 1995 was reviewed. Part 1: Implants and Biologic Response in Two Patient Cohorts Restored Between 1986 and 1987 and 15 Years Later, Implant treatment with fixed prostheses in the edentulous maxilla. One implant was lost due to infection. Baseline bone height was 4.92 +/- 1.24 mm. Compared with other methods based on laser or optical geometric measurements, the shadow-speckle method overcomes their limitations by using a digital image correlation to reconstruct a 3D tooth model. The patients found the esthetics to be excellent. Data on the selection of shade for 2,500 metal ceramic crown units, placed over a 5-year period at the University Dental Hospital of Manchester, were collected and analyzed. Nonvital teeth showed a significantly higher risk of failure (P < .0001). The aim of this study was to determine the effect of long-term water immersion on the flexural properties of fiber-reinforced composite. Two types of implants were used (141 titanium plasma-sprayed and 124 Sand-blasted, large-grit, acid-etched). Twenty-five randomly selected Japanese dental clinicians in 1995 and 2005 with 5 to 15 years of clinical experience were requested to define bone support levels for prosthodontic treatment options. The degree of satisfaction was indicated with a visual analog scale. The success rate for the gold-resin restorations was less favorable: 43% remained unchanged and 33% had been removed. The results suggest that single-tooth replacement using osseointegrated implants provides predictable success. Twelve clinicians at nine clinics placed 87 crowns in 50 patients. China Hong-Chang Lai, DDS ... All members of the Journal of Prosthodontics Editorial Board and Editorial Review Board have been asked to sign Conflict of Interest disclosure statements. A total of 207 implants were placed in 72 patients, and 182 implants had been uncovered. Severe morphologic alterations and pronounced DNA damage were also observed.

Prosthetic treatment was performed using significantly less chair time in the late group (P < .05), and 22 and 68 patients were followed for 5 years without any reported complications in the early and late groups, respectively (P < .05). The early group included 76 edentulous patients who were consecutively provided with 450 turned Branemark System implants; the late group included 109 edentulous patients provided with 360 turned and 310 TiUnite Branemark System implants. Other Titles: Title Abbreviation: Int J Prosthodont Title(s): The International journal of prosthodontics. PI and BOP were not directly related to the frequency of failures. Conclusion: This 18-year follow-up of metal-ceramic FPDs in just over half of the originally treated patient group was associated with good patient satisfaction and few biologic and technical complications. Six crowns (7%) were recorded as failures; five of these crowns (6%) had to be remade. A total of 9 patients (10 implants) was lost to follow-up. One or more of these radiographic observations were found in 51.7% of the examined films. During a mean observation time of 46.57 months, 35 VRFPDs on vital abutment teeth did not exhibit postoperative sensitivity or secondary caries. Some of the AllCeram crowns were among the very first that were placed. No correlation was found between oral stereognostic ability and the SCL-90-R or CES-D values. 1 (23.12.2019) Page 99-104, doi:10.11607/ijp.6348, PubMed:31860919 Preliminary Clinical Application of Complete Workflow of Digitally Designed and … The mean inflated balloon volume was 0.67 +/- 0.17 mL. It is possible to achieve high survival rates of implants in the auricular and piriform/nasal sites through careful presurgical and radiographic planning. International journal of prosthodontics (GYFmHBV)099227436: Material Type: Periodical: Document Type: Journal / Magazine / Newspaper: ISSN: 0893-2174: OCLC Number: 614360530: Notes: Zusatz bis 19.2006: Official journal of International College of Prosthodontists, International Society of Maxillofacial Rehabilitation. Each framework was compared with a hybrid composite FPD without any fiber reinforcement (C-FPD). EndNote Styles - International Journal of Prosthodontics. Int J Prosthodont 2010;23:243-245. Only 6.3% of the impressions were unacceptable and categorized as Criteria III. The aim of this study was to assess the cytotoxicity of 4 resin composites' eluates on WEHI 13 Var fibroblasts as they aged in a biologic medium. An analysis of retrospective data was conducted to establish the survival rates of osseointegrated implants used to retain orbital, nasal, and auricular prostheses over a 14-year period and to recommend guidelines in the restorative treatment of such facial defects. This study investigated the survival of complete crowns in relation to periodontal variables on a long-term basis. The long-term results were good, especially for the metal ceramic restorations: 79% remained unchanged and only 3% had been removed. Pre- and postoperative panoramic films or computed tomographs (optional) were taken for every case to measure and compare the results of the sinus membrane lift using a water balloon. The differences between the three groups were evaluated 6.5 years after treatment. All patients who received oral implants in 1990* and in 1995 were selected, and their files (95 and 105, respectively) were consulted. Int J Prosthodont 2011;24:345-355. Thus, psychogenic prosthesis incompatibility can be classified more explicitly as a psychosomatic disorder. In cases of epigingival and subgingival (< 2 mm) preparation margins, MFC was a less traumatic alternative method of gingival retraction. Prosthetic work should be preceded by periodontal examination and prophylactic and periodontal treatment if needed. Journal of Prosthodontic Research originated as an official journal of Japan Prosthodontic Society. The 14-year cumulative survival rates for all short and standard implants were 97.9% and 97.1%, respectively. A surgical guide was obtained by a 3D printer, and the surgical procedure was done using the Biohorizons Guided Surgery Kit and its protocol. Survival rates were 92.3% and 95.9% for titanium plasma-sprayed short and standard implants, respectively, and 100% and 98.5% for the Sand-blasted, large-grit, acid-etched short and standard implants, respectively. Read more. Periodontal variables were measured, including Plaque Index (PI), bleeding on probing (BOP), probing pocket depth (PPD), and attachment level. MMT was measured bilaterally using an ultrasound scanner during 1 year of wearing a conventional denture, after 101 days of voluntary denture abstention, and 3, 6, and 12 months after delivery of the IOD. The Journal of Prosthodontics promotes the advanced study, science, and practice of prosthodontics, implant, esthetic, and reconstructive dentistry.It is the official journal of the American College of Prosthodontists, the association that represents the dental specialty of prosthodontics. The 5-year overall implant cumulative survival rates were 93.4% and 97.3% for the early and late groups, respectively. Both groups were followed for 5 years with regard to prosthetic treatment, clinical maintenance, and complications. Data provided are for informational purposes only. The overall success rate of cantilever fixed prostheses was 70% over a period of 18 years. Implant treatment has been performed for more than 45 years, but there is still limited knowledge on how treatment outcomes are changing over time. Control specimens were unreinforced. Catch up on the latest ICP News! Esthetic match, porcelain surface, marginal discoloration, and integrity were evaluated following modified California Dental Association/Ryge criteria. This study obtained information on the long-term efficiency of prosthetic rehabilitation with fixed partial dentures performed by undergraduate students. The results of this study demonstrate about the same clinical outcome as has been reported by similar studies on all-ceramic crowns built on a core of alumina. INTERNATIONAL. A 55-year-old Japanese woman received periodontal therapy and cross-arch fixed partial dentures were placed in the maxilla and mandible. ICP Biennial Meeting. In the early group, significantly more turned implants failed before prosthesis insertion compared to the outcome of TiUnite implants in the late group (P < .05). Furthermore we use Google Analytics to create anonymized statistical reports of the usage which creates Cookies too. Fibers were oriented at a 45-degree angle to the long axis of the test specimens. Implant treatment was more predictable before loading in the late group of patients, related to the change in the implant surface (P < .05). Dropouts were recorded for 23 patients with 23 prostheses supported by 42 implants. Welcome to THE INTERNATIONAL JOURNAL OF PROSTHODONTICS's online manuscript submission and peer-review system Thank you for submitting to IJP! Two hundred eighty-three of the resin-bonded fixed partial dentures were primary restorations, and 42 of the restorations were secondary and tertiary after the loss of the primary resin-bonded fixed partial denture. Cementation using Variolink showed significantly fewer failures than Optec Cement (P = .0217) and Dual Cement (P = .0099). Cantilevered IPS e.max Press VRFPDs should be considered a minimally invasive, single-tooth restorative strategy in the anterior or first premolar area. The International Journal of Oral & Maxillofacial Implants (40) The International Journal of Periodontics & Restorative Dentistry (32) The International Journal of Prosthodontics (33) Thematic Abstract Review (4) What's New (98) Fewer metal ceramic restorations than acrylic resin veneer-gold restorations were removed. Thirty-three of the prostheses were located in the mandible (11 in the anterior and 22 in the posterior region) and 104 were located in the maxillae (58 anterior prostheses and 46 posterior prostheses). The results revealed no significant differences in oral stereognostic ability between patients with diagnosed psychogenic dental prosthesis incompatibility and the control patients. The International Journal of Prosthodontics. Statistical analysis (Spearman Rank Order) showed a significant difference between all groups (P < .05) but not within groups (P > .05). The study cohort comprised 83 patients with complete dentures fabricated according to a standardized protocol. In this article, the authors present a clinical case in which a guided implant surgery was performed based on a complete digital surgical plan combining the information from a cone beam computed tomography scan and the virtual simulation obtained from the 3Shape TRIOS intraoral surface scanner. The International Journal of Prosthodontics > 2017-01-14 The International Journal of Prosthodontics Follow New on 2017 Jan 14: Survey of Dental Materials Used by Dentists for Indirect Restorations in Saudi Arabia Y Haider et al. Caries was the most frequent reason for failure, followed by periodontal disease. The California Dental Association quality evaluation system was used for assessment of marginal integrity and esthetics. A significant influence on the quality of the impressions was found when the preparation finish line was more than 2 mm subgingivally for shoulder (P < .004) as well as beveled preparations (P < .004). The Journal of Prosthetic Dentistry is the leading professional journal devoted exclusively to prosthetic and restorative dentistry.The Journal is the official publication for 24 leading U.S. international prosthodontic organizations. Only those crowns placed adjacent to minimally restored vital teeth were included in the study. Page 487-492, doi:10.11607/ijp.6470, PubMed:32956429 Perceptibility and Acceptability of Color Differences of Single-Tooth Implants at the Restoration … Odds ratios were 1.00 for both PI and BOP. Also, in 1995 more maxillae were implanted than in 1990* (44% vs 26%). In contrast, the survival rate for orbital implants showed a steady downward trend and reached 59% at 66 months. Differences in fit between experimental specimens and custom-made ones showed that experimental results might not always be obtained in clinical practice. The results indicate a good prognosis for Procera AllCeram crowns also for posterior teeth. In the remaining 106 patients (223 implants), 8 implants failed (4 standard and 4 shorter), in type 3 or 4 bone. The patient group of < or = 40 years of age had significantly increased, from 7% to 23%. The mean follow-up period was 17.7 years (range: 17.1 to 21.3 years). A removable partial denture was retained by the attachments and conventional cast retentive circumferential clasps, including a hollow obturator filling the defect. In all FRC-FPD models, the FRC framework showed stress-bearing capacity for the FPD. A fiber framework of the pontic was designed with three variations: with the main framework curved labially (FRC1), located in the center (FRC2), or curved lingually (FRC3). The Standard Abbreviation (ISO4) of International Journal of Prosthodontics is “Int J Prosthodont”.ISO 4 (Information and documentation – Rules for the abbreviation of title words and titles of publications) is an international standard, defining a uniform system for the abbreviation of serial publication titles.

The purpose of this study was to investigate the distribution of shades selected for metal ceramic crowns provided at a dental teaching hospital. The bone loss was of the same magnitude as in other studies on Brånemark implants as support for single crowns. These results suggest that it may be possible to place a resin-bonded prosthesis on an abutment tooth that has been restored using a spherical amalgam alloy. Twenty-eight total implants (diameter: 3.8 to 5.0 mm) were placed. Of the 269 impressions evaluated, 93.7% were clinically acceptable and showed complete reproduction of the preparation finish line; 17.5% showed small defects but the impressions were still rated clinically acceptable and categorized as Criteria II. Reasons for failure included abutment fracture (4), loosening with or without caries (18), secondary caries (9), fracture of prosthesis (2), fracture of extension (1), periodontal problems (6), and apical reaction (1). There was no difference in removal frequency between fixed partial dentures with moderate cantilever extensions and those with end-supported extensions. Mucosal hyperplasia and inflammation showed a trend of higher frequency at implants in the early group of patients (P > .05). A total of 8 crowns was remade following prosthetic complications; otherwise, the frequency of adverse events was low. They were placed on your computer when you launched this website. The information was imported to and combined in the 3Shape Implant Studio software for guided implant surgery planning. Auricular implants showed the highest survival rate (95%), and orbital implants showed the lowest survival rate (53%). Panoramic radiographs from 271 patients who were edentulous in one or both arches were evaluated for the presence of retained root fragments, impacted teeth, foreign bodies, radiolucencies, radiopacities, mental foramina at or near the crest of the residual alveolar ridge, and maxillary sinus proximity to the crest of the residual alveolar ridge. Data of interest were retrieved retrospectively, compared, and statistically analyzed using Chi-squared tests. ICP Newsletter - September 2020. There were 259 implants placed in 183 patients with a mean age of 29.8 years; 230 (89%) were placed in the maxilla and 29 (11%) were placed in the mandible. The type of amalgam and the brand of aluminum oxide affected the bond strength of the resin to amalgam alloy. Complete treatment and follow-up records of 1,037 CCs (60.5% women/39.5% men; age range: 18 to 82 years), 134 3uFDPs (59.2% women/40.8% men; age range: 33.6 to 93.6 years), and 322 FDPs (62.1% women/37.9% men; age range: 33.6 to 94.2 years) were available for analysis. For the surviving restorations, the improved PI over time was statistically significant (P = .001). The prosthesis length ratio and the crown length-bone ratio did not influence the failure rate. The aim of the study was to evaluate AllCeram crowns in dental practice over a 5- to 10.5-year period. One hundred thirty-seven cantilevered fixed partial dentures made between 1974 and 1990 were clinically and radiographically evaluated. MMT decreased by 17% during denture abstention following repeated implant surgery, and returned to 100% during the 12 months with the mandibular IOD. Within the limitations of the protocol of this study, the minimum number of measurements required to ensure relevant results for gap analysis was 18 for experimental and 90 for custom-made crowns. Mean bone loss was comparable for the early and late groups during the 5 years of follow-up (0.5 ± 0.46 and 0.7 ± 0.76 mm, respectively), but more patients presented at least 1 implant with more than 2 mm of bone loss during the follow-up period in the late group (P < .05). The main reason for failure was fracture of the ceramic (33.68%). A Siroflow abrasion unit was used to treat four groups of ten specimens that were subjected to 5, 10, 20, and 40 seconds of abrasion respectively. An International Survey among Prosthodontists of the Use of Mandibular Implant‐Supported Dental Prostheses. No fractures or chipping of the restorations occurred within the course of the evaluation. The minimum number of gap measurements required to produce relevant results for gap analysis was also investigated. Two methods were used to determine survival rates: (1) the percentage of the total exposed implants that survived was determined, and (2) life table analysis was used to calculate cumulative survival rates at different time intervals. The relationship between age versus irreversible complications for the fixed prosthetic restorations was statistically significant for all test groups. Osseointegration has influenced the decision-making process in prosthodontic treatments related to extraction. The patients with the failing restorations (66.2 years; mean range: 64.8 to 67.5 years) were 4.5 to 5.5 years older at initial treatment than the patients with the surviving restorations (61.3 years; mean range: 59.5 to 63.0 years). It has recently developed a long-range plan to become the most prestigious Asian journal of dental research regarding all aspects of oral and occlusal rehabilitation, fixed/removable prosthodontics, oral implantology and applied oral biology and physiology. Longer observation periods are necessary before this type of restorative design can be recommended as a general conservative procedure. This was the first documented study to use the SCL-90-R and CES-D scales on patients with suspected psychogenic dental prosthesis incompatibility with nonadaptation 6 months after incorporation. He has lived a normal family life and finished his university education. The results were similar to those for complete and partial osseointegrated prostheses. The ability to displace gingiva was indirectly measured by the quality of the final impression. This study evaluated the marginal fit of experimental and custom-made fixed prosthetic restorations through a new 360-degree external examination. For further information, please contact Rachel Yehl at ryehl@prosthodontics.org. The majority (85%) of the fixed partial dentures were acrylic resin veneer-gold restorations; 15% were metal ceramic restorations. Knowledge of the distribution of shades selected for permanently luted metal ceramic crowns may be a useful adjunct in shade selection, particularly for the inexperienced operator. The patients' complaints with the restorations included taste disorders, odynophagia, pain sensations, and functional and esthetic dissatisfaction. Int J Prosthodont 2011;24:356-362. During this study period, 14 individuals died, leaving 138 fixed partial dentures to be examined. After 18 years, STE developed in the left posterior region of the mandible. Carious lesions were found on 4% of the abutment teeth. The international journal of prosthodontics.. [International College of Prosthodontist,;] Official Journal of the International College of Prosthodontists and the International Society for Maxillofacial Rehabilitation. Of the prosthetic restorations, 165 were all-ceramic (68%), 79 were metal-ceramic (31%), and 4 were gold-acrylic (1%). The study population was a mixture of periodontally affected and non-periodontally affected patients, which is comparable to the population group in a private practice. This study is the first to use oral stereognosis tests for patients with psychologically diagnosed psychogenic dental prosthesis incompatibility. These findings indicate that resin-based dental restorative materials release agents cytotoxic and genotoxic to fibroblasts. Dry test specimens and those stored in water for up to 180 weeks were tested with a 3-point loading apparatus.

Data were obtained from patient charts. Two implants were lost as a result of suppuration caused by membrane exposure, while another was lost after loading. Purpose: To establish a complete digital workflow for the design and manufacture of sports mouthguards and to observe preliminary clinical effects. The most frequent finding (30.6%) was close approximation of the maxillary sinus to the crest of the ridge. The editors of the Journal of Prosthodontics are pleased to present this virtual issue on the latest technological advances in ceramics. The monthly publication features timely, original peer-reviewed articles on the newest techniques, dental materials, and research findings. The aim of this study was to evaluate a new gingival retraction system relative to clinical success for fixed dental restorations under various clinical conditions. Results: Altogether, 37 patients (20%) were lost to follow-up during the 5 years, and more patients were noncompliant in the late group (P < .05). Evidence-based dentistry 2006: Where are we? Purpose: The aim of this clinical retrospective study was to evaluate the survival and success rates of metal-ceramic fixed partial dentures (FPDs) made by dental students over an 18-year interval. The maxillary posterior teeth were then placed palatally to maximize occlusal contacts with the opposing mandibular teeth. When compared with the control group, patients with suspected psychogenic dental prosthesis incompatibility showed statistically significant differences in the CES-D cumulative values (P = .015) and the SCL-90-R values Global Severity Index (P = .024) and Positive Symptom Distress Index (P = .049). Mats Kronstrom DDS, Odont Dr, PhD; Gunnar E. Carlsson LDS, Odont Dr, PhD; Pages: e622-e626; First Published: 17 March 2017 Furthermore, shades in the reddish-grey range of hue were rarely chosen. First, the fossa of mandibular posterior teeth was positioned on the crest of the mandibular edentulous ridge. To gain more insight into the treatment strategies for edentulous patients with atrophic ridges, three groups of patients were evaluated: group 1, patients with atrophy of the mandible who needed preprosthetic surgery but who only received new dentures because surgery was contraindicated; group 2, patients in the same oral condition as those in group 1 who were treated with vestibuloplasty and lowering of the floor of the mouth before fabrication of new dentures; group 3, the control group of patients without residual ridge-related problems who were treated with new complete dentures. The results indicate that the most frequently chosen shades were in the mid-range of reddish-brown hue. The diagnosis of psychogenic prosthesis incompatibility by the SCL-90-R and CES-D scales is affirmed by the lack of correlations between the functional/anatomic aspects of oral stereognostic ability, psychologic diagnostic tools, and the clinical picture of psychogenic prosthesis incompatibility. ICP journal. Materials and methods: The 5-year prosthesis cumulative survival rate was 97.1% in the early group and 100.0% in the late group. During the study period, 35 implants failed to integrate, and the survival rate for all exposed implants was 80%. The selection of more than one shade for a crown ("mixed shades") was generally restricted to the maxillary anterior teeth. One cantilevered pontic needed adjustment on the incisal edge due to premature contacts after the 3-year recall examination. The study population included 106 (35.1%) individuals diagnosed with bruxism. Included in this study were all patients who received implant-retained prostheses for auricular, nasal, or orbital defects from 1987 to 2001 in the Maxillofacial Clinics at the UCLA and City of Hope Medical Centers. All-ceramic restorations offer a predictable and successful restoration with an estimated survival probability of 93.5% over 10 years. Scanning electron micrographs showed smear layer removal as an immediate effect of air polishing. Post hoc analysis revealed that after the storage of 4 weeks no statistically significant reduction occurred. Editor-in-Chief: George A. Zarb Official journal of the International College of Prosthodontists, International Society for Maxillofacial Rehabilitation, German Society for Prosthodontics and Dental Materials Science, and Italian Academy of Prosthetic Dentistry Volume 26, 2013 Subscription Rates (Includes free Web access to all back issues) Conclusion: Following removal of a rare tumor, a young man was treated with gold crowns on three molars and a metal-ceramic crown on a first premolar, with attachments in the areas facing the defect for esthetic reasons. The stability of the mandibular dentures as well as the retention were better in group 2 than were those in group 1. By 1995 there was a threefold increase in both the number of patients and the number of implants placed per year. ACP members must be logged in to access the Journal.. The estimated survival rate was 97.3% after 5 years, 93.5% at 10 years, and 78.5% at 20 years. The patients in the test group expressed clear dissatisfaction with their dentures. There was no relationship between gender and irreversible complications. Endodontic complications on abutment teeth were more frequent in the mandible than in the maxillae. Bio-Oss was filled under the elevated sinus membrane using a dedicated instrument. Ceramics in Prosthodontics. Patients in the late group presented fewer problems with diction and veneer fractures, and fewer patients had their prostheses temporarily removed for adjustments (P < .05). A number of statistically significant differences was apparent between these 2 periods. EndNote Styles - International Journal of Prosthodontics. The results have direct implications on socioeconomic and forensic consequences for diagnosis and treatment by a dental clinician. The International Journal of Prosthodontics is dedicated to exploring and developing this conceptual shift in the role of today's prosthodontist, clinician, and educator alike. There were 3 implant failures registered, one before loading and one during the first year in function; one implant fractured after 6 years in service, giving a cumulative success rate for implants of 98.3%. The remaining 2 lost implants were managed by converting the distal unit of the fixed partial prosthesis to a cantilever. Both groups were followed and evaluated clinically and radiographically for 5 years according to similar protocols. Failures occurred significantly more when endodontically treated abutments were used. SCOPE.

Provides the worldwide dental community with current, scientifically sound information on patient care, research, and education in prosthodontics and interrelated disciplines. Base metal alloys, silicoating, mesh retention, and immobile abutments were positive factors. Computed tomography showed the bone graft distributing evenly around implants. Author(s): International College of Prosthodontists. More mandibular restorations failed than did maxillary units, but the difference was not significant. This study confirms the favorable results presented in other studies on Brånemark implants to support single-tooth restorations. The resistance against dislodgment of the denture was low in all three groups. Sixty-seven screw-type standard, self-tapping implants and mini-implants were placed. Implant Treatment with Fixed Prostheses in the Edentulous Maxilla. The use of a water balloon to elevate the sinus membrane is a truly minimally invasive technique and is associated with very little discomfort. The less favorable long-term survival of implants in the orbital rim, especially at irradiated sites, requires further study. The life table analysis demonstrated a cumulative 6-year survival rate of 92% for auricular implants and 87% for piriform/nasal implants. Materials and Methods: Fifty-seven patients with 82 FPDs from an original group of 104 patients with 128 FPDs attended an approximate clinical 18-year follow-up examination. Patients receiving artificial crowns and fixed partial dentures at a prosthodontic clinic were examined 18 to 23 years after treatment. Using the SCL-90-R and CES-D, it was possible to make a reliable initial diagnosis of the psychosomatic clinical situation regarding psychogenic prosthesis incompatibility. Multiunit resin-bonded fixed partial dentures had a smaller probability of survival than three-unit resin-bonded fixed partial dentures. The aim of this study was to investigate the optimal design of a fiber-reinforced composite (FRC) framework to obtain the maximum reinforcement for fixed partial dentures (FPDs) under three different loading conditions using three-dimensional finite element (FE) analysis. In contrast to other reports in the literature, retentive abutment preparation did not result in a higher survival rate than unprepared abutments. This case suggests that muscle bulk may be related to denture function. The editorial board is composed of a distinguished team of leading international scholars. The mean observation time was 102 ± 60 months. Group 2 patients scored comparably or higher than the normal ridge group (group 3). Patients were offered a supportive maintenance program. Number of restoration failures and reasons for failure were recorded. A total of 163 fixed partial dentures were inserted. This study aimed to investigate the occurrence of subpontic tissue enlargement (STE) beneath a mandibular fixed partial denture. Patients with a high CPITN at baseline had a 3.8 times greater likelihood of losing a complete crown (and abutment tooth) than patients with a low CPITN.

The International Journal of Prosthodontics is dedicated to exploring and developing this conceptual shift in the role of today's prosthodontist, clinician, and educator alike. The use of digital surface scanners with surgical planning software allows for the combination of the radiographic, prosthetic, surgical, and laboratory fields under a common virtual scenario, permitting complete digital treatment planning. From a list of discharged patients treated from 1975 to 1976 by undergraduate students at a dental school, 101 were recalled for free clinical examinations after 6, 11, and 18 years. There is a trend toward implanting younger patients for partial implant-supported reconstructions using more regenerative procedures and with a more equal distribution in the maxilla and mandible. http://www.quintpub.com/journals/ijp/gp.php?journal_name=IJP&name_abbr=IJP, Clinical long-term evaluation and failure characteristics of 1,335 all-ceramic restorations, Procera AllCeram Crowns Followed for 5 to 10.5 Years: A Prospective Clinical Study, 11-Year Follow-up Study of Resin-Bonded Fixed Partial Dentures, In vitro assessment of cytotoxicity of resin-based dental restorative materials on WEHI 13 Var fibroblasts, Implant-Retained Prostheses for Facial Defects: An Up to 14-Year Follow-up Report on the Survival Rates of Implants at UCLA, Short (8-mm) dental implants in the rehabilitation of partial and complete edentulism: A 3- to 14-year longitudinal study, Prosthetic restoration following removal of chondrosarcoma in the premaxillary region: A case presentation and follow-up for 16 years, Survival of complete crowns and periodontal health: 18-year retrospective study, A Study of Fixed Prosthodontics Performed at a University Clinic 18 Years after Insertion, 18-Year longitudinal study of cantilevered fixed restorations, Subpontic Tissue Enlargement of the Mandible Following Cross-Arch Fixed Partial Denture Reconstruction: An 18-Year Follow-up, Artificial crowns and fixed partial dentures 18 to 23 years after placement, An 18-Year Retrospective Analysis of Treatment Outcomes with Metal-Ceramic Fixed Partial Dentures, The influence of gender and age on fixed prosthetic restoration longevity: An up to 18- to 20-year follow-up in an undergraduate clinic, Effect of 180-Week Water Storage on the Flexural Properties of E-Glass and Silica Fiber Acrylic Resin Composite.

This case report describes the effect of complete denture abstention and subsequent rehabilitation with mandibular implant-supported overdentures (IOD) on masseter muscle thickness (MMT) in a 97-year-old patient. We are now at the center of another grand transformation… One of the principal technologies of this new mode of production and social organization is the Internet. Purpose: Implant treatment using osseointegrated implants has been performed for more than 40 years, but limited knowledge is available on how treatment outcomes have changed over time. The highest stress reduction ratio under all loading conditions was obtained using the FRC1 model. One major use of ISO 4 is to abbreviate the names of scientific journals. Furthermore we use Google Analytics to create anonymized statistical reports of the usage which creates Cookies too. After 5 and 10 years a cumulative survival rate of 97.7% and 93.5%, respectively, and a cumulative success rate of 97.7% and 92.2%, respectively, was recorded. No differences in survival rate were found for resin-bonded fixed partial dentures in the maxillae or mandible, or in the anterior and posterior regions. This case series study evaluated the clinical outcomes of cantilevered veneer-retained fixed partial dentures (VRFPDs) fabricated with IPS e.max Press for single-tooth replacement in the anterior arch. Results: Nine FPDs were lost because of extraction of an abutment tooth, and 1 FPD was removed for esthetic reasons. When the spherical alloy was air abraded using 60-microns aluminum oxide prior to cementation of a Rexillium rod using Panavia, the bond strength was not significantly different from the previously reported bond strengths of Panavia to etched enamel. The patients were evaluated at baseline and annually from October 2005 to July 2011 for the integrity of the VRFPDs, proximal contacts, occulsal relationships, pulp vitality, and tooth mobility. Successful sinus membrane water balloon lifting procedures were performed in 26 cases; two procedures were aborted due to sinus membrane perforation. Those statements are on file at the editorial office. International Journal of Periodontics & Restorative Dentistry. Dresden, 23-26 May 2002. For the last several years, this procedure has also been used for single-tooth replacement following loss of teeth for traumatic, periodontal, and carious lesions. The clinical performance of 325 resin-bonded fixed partial dentures (RBFPD) placed between 1984 and 1995 was reviewed. Part 1: Implants and Biologic Response in Two Patient Cohorts Restored Between 1986 and 1987 and 15 Years Later, Implant treatment with fixed prostheses in the edentulous maxilla. One implant was lost due to infection. Baseline bone height was 4.92 +/- 1.24 mm. Compared with other methods based on laser or optical geometric measurements, the shadow-speckle method overcomes their limitations by using a digital image correlation to reconstruct a 3D tooth model. The patients found the esthetics to be excellent. Data on the selection of shade for 2,500 metal ceramic crown units, placed over a 5-year period at the University Dental Hospital of Manchester, were collected and analyzed. Nonvital teeth showed a significantly higher risk of failure (P < .0001). The aim of this study was to determine the effect of long-term water immersion on the flexural properties of fiber-reinforced composite. Two types of implants were used (141 titanium plasma-sprayed and 124 Sand-blasted, large-grit, acid-etched). Twenty-five randomly selected Japanese dental clinicians in 1995 and 2005 with 5 to 15 years of clinical experience were requested to define bone support levels for prosthodontic treatment options. The degree of satisfaction was indicated with a visual analog scale. The success rate for the gold-resin restorations was less favorable: 43% remained unchanged and 33% had been removed. The results suggest that single-tooth replacement using osseointegrated implants provides predictable success. Twelve clinicians at nine clinics placed 87 crowns in 50 patients. China Hong-Chang Lai, DDS ... All members of the Journal of Prosthodontics Editorial Board and Editorial Review Board have been asked to sign Conflict of Interest disclosure statements. A total of 207 implants were placed in 72 patients, and 182 implants had been uncovered. Severe morphologic alterations and pronounced DNA damage were also observed.

Prosthetic treatment was performed using significantly less chair time in the late group (P < .05), and 22 and 68 patients were followed for 5 years without any reported complications in the early and late groups, respectively (P < .05). The early group included 76 edentulous patients who were consecutively provided with 450 turned Branemark System implants; the late group included 109 edentulous patients provided with 360 turned and 310 TiUnite Branemark System implants. Other Titles: Title Abbreviation: Int J Prosthodont Title(s): The International journal of prosthodontics. PI and BOP were not directly related to the frequency of failures. Conclusion: This 18-year follow-up of metal-ceramic FPDs in just over half of the originally treated patient group was associated with good patient satisfaction and few biologic and technical complications. Six crowns (7%) were recorded as failures; five of these crowns (6%) had to be remade. A total of 9 patients (10 implants) was lost to follow-up. One or more of these radiographic observations were found in 51.7% of the examined films. During a mean observation time of 46.57 months, 35 VRFPDs on vital abutment teeth did not exhibit postoperative sensitivity or secondary caries. Some of the AllCeram crowns were among the very first that were placed. No correlation was found between oral stereognostic ability and the SCL-90-R or CES-D values. 1 (23.12.2019) Page 99-104, doi:10.11607/ijp.6348, PubMed:31860919 Preliminary Clinical Application of Complete Workflow of Digitally Designed and … The mean inflated balloon volume was 0.67 +/- 0.17 mL. It is possible to achieve high survival rates of implants in the auricular and piriform/nasal sites through careful presurgical and radiographic planning. International journal of prosthodontics (GYFmHBV)099227436: Material Type: Periodical: Document Type: Journal / Magazine / Newspaper: ISSN: 0893-2174: OCLC Number: 614360530: Notes: Zusatz bis 19.2006: Official journal of International College of Prosthodontists, International Society of Maxillofacial Rehabilitation. Each framework was compared with a hybrid composite FPD without any fiber reinforcement (C-FPD). EndNote Styles - International Journal of Prosthodontics. Int J Prosthodont 2010;23:243-245. Only 6.3% of the impressions were unacceptable and categorized as Criteria III. The aim of this study was to assess the cytotoxicity of 4 resin composites' eluates on WEHI 13 Var fibroblasts as they aged in a biologic medium. An analysis of retrospective data was conducted to establish the survival rates of osseointegrated implants used to retain orbital, nasal, and auricular prostheses over a 14-year period and to recommend guidelines in the restorative treatment of such facial defects. This study investigated the survival of complete crowns in relation to periodontal variables on a long-term basis. The long-term results were good, especially for the metal ceramic restorations: 79% remained unchanged and only 3% had been removed. Pre- and postoperative panoramic films or computed tomographs (optional) were taken for every case to measure and compare the results of the sinus membrane lift using a water balloon. The differences between the three groups were evaluated 6.5 years after treatment. All patients who received oral implants in 1990* and in 1995 were selected, and their files (95 and 105, respectively) were consulted. Int J Prosthodont 2011;24:345-355. Thus, psychogenic prosthesis incompatibility can be classified more explicitly as a psychosomatic disorder. In cases of epigingival and subgingival (< 2 mm) preparation margins, MFC was a less traumatic alternative method of gingival retraction. Prosthetic work should be preceded by periodontal examination and prophylactic and periodontal treatment if needed. Journal of Prosthodontic Research originated as an official journal of Japan Prosthodontic Society. The 14-year cumulative survival rates for all short and standard implants were 97.9% and 97.1%, respectively. A surgical guide was obtained by a 3D printer, and the surgical procedure was done using the Biohorizons Guided Surgery Kit and its protocol. Survival rates were 92.3% and 95.9% for titanium plasma-sprayed short and standard implants, respectively, and 100% and 98.5% for the Sand-blasted, large-grit, acid-etched short and standard implants, respectively. Read more. Periodontal variables were measured, including Plaque Index (PI), bleeding on probing (BOP), probing pocket depth (PPD), and attachment level. MMT was measured bilaterally using an ultrasound scanner during 1 year of wearing a conventional denture, after 101 days of voluntary denture abstention, and 3, 6, and 12 months after delivery of the IOD. The Journal of Prosthodontics promotes the advanced study, science, and practice of prosthodontics, implant, esthetic, and reconstructive dentistry.It is the official journal of the American College of Prosthodontists, the association that represents the dental specialty of prosthodontics. The 5-year overall implant cumulative survival rates were 93.4% and 97.3% for the early and late groups, respectively. Both groups were followed for 5 years with regard to prosthetic treatment, clinical maintenance, and complications. Data provided are for informational purposes only. The overall success rate of cantilever fixed prostheses was 70% over a period of 18 years. Implant treatment has been performed for more than 45 years, but there is still limited knowledge on how treatment outcomes are changing over time. Control specimens were unreinforced. Catch up on the latest ICP News! Esthetic match, porcelain surface, marginal discoloration, and integrity were evaluated following modified California Dental Association/Ryge criteria. This study obtained information on the long-term efficiency of prosthetic rehabilitation with fixed partial dentures performed by undergraduate students. The results of this study demonstrate about the same clinical outcome as has been reported by similar studies on all-ceramic crowns built on a core of alumina. INTERNATIONAL. A 55-year-old Japanese woman received periodontal therapy and cross-arch fixed partial dentures were placed in the maxilla and mandible. ICP Biennial Meeting. In the early group, significantly more turned implants failed before prosthesis insertion compared to the outcome of TiUnite implants in the late group (P < .05). Furthermore we use Google Analytics to create anonymized statistical reports of the usage which creates Cookies too. Fibers were oriented at a 45-degree angle to the long axis of the test specimens. Implant treatment was more predictable before loading in the late group of patients, related to the change in the implant surface (P < .05). Dropouts were recorded for 23 patients with 23 prostheses supported by 42 implants. Welcome to THE INTERNATIONAL JOURNAL OF PROSTHODONTICS's online manuscript submission and peer-review system Thank you for submitting to IJP! Two hundred eighty-three of the resin-bonded fixed partial dentures were primary restorations, and 42 of the restorations were secondary and tertiary after the loss of the primary resin-bonded fixed partial denture. Cementation using Variolink showed significantly fewer failures than Optec Cement (P = .0217) and Dual Cement (P = .0099). Cantilevered IPS e.max Press VRFPDs should be considered a minimally invasive, single-tooth restorative strategy in the anterior or first premolar area. The International Journal of Oral & Maxillofacial Implants (40) The International Journal of Periodontics & Restorative Dentistry (32) The International Journal of Prosthodontics (33) Thematic Abstract Review (4) What's New (98) Fewer metal ceramic restorations than acrylic resin veneer-gold restorations were removed. Thirty-three of the prostheses were located in the mandible (11 in the anterior and 22 in the posterior region) and 104 were located in the maxillae (58 anterior prostheses and 46 posterior prostheses). The results revealed no significant differences in oral stereognostic ability between patients with diagnosed psychogenic dental prosthesis incompatibility and the control patients. The International Journal of Prosthodontics. Statistical analysis (Spearman Rank Order) showed a significant difference between all groups (P < .05) but not within groups (P > .05). The study cohort comprised 83 patients with complete dentures fabricated according to a standardized protocol. In this article, the authors present a clinical case in which a guided implant surgery was performed based on a complete digital surgical plan combining the information from a cone beam computed tomography scan and the virtual simulation obtained from the 3Shape TRIOS intraoral surface scanner. The International Journal of Prosthodontics > 2017-01-14 The International Journal of Prosthodontics Follow New on 2017 Jan 14: Survey of Dental Materials Used by Dentists for Indirect Restorations in Saudi Arabia Y Haider et al. Caries was the most frequent reason for failure, followed by periodontal disease. The California Dental Association quality evaluation system was used for assessment of marginal integrity and esthetics. A significant influence on the quality of the impressions was found when the preparation finish line was more than 2 mm subgingivally for shoulder (P < .004) as well as beveled preparations (P < .004). The Journal of Prosthetic Dentistry is the leading professional journal devoted exclusively to prosthetic and restorative dentistry.The Journal is the official publication for 24 leading U.S. international prosthodontic organizations. Only those crowns placed adjacent to minimally restored vital teeth were included in the study. Page 487-492, doi:10.11607/ijp.6470, PubMed:32956429 Perceptibility and Acceptability of Color Differences of Single-Tooth Implants at the Restoration … Odds ratios were 1.00 for both PI and BOP. Also, in 1995 more maxillae were implanted than in 1990* (44% vs 26%). In contrast, the survival rate for orbital implants showed a steady downward trend and reached 59% at 66 months. Differences in fit between experimental specimens and custom-made ones showed that experimental results might not always be obtained in clinical practice. The results indicate a good prognosis for Procera AllCeram crowns also for posterior teeth. In the remaining 106 patients (223 implants), 8 implants failed (4 standard and 4 shorter), in type 3 or 4 bone. The patient group of < or = 40 years of age had significantly increased, from 7% to 23%. The mean follow-up period was 17.7 years (range: 17.1 to 21.3 years). A removable partial denture was retained by the attachments and conventional cast retentive circumferential clasps, including a hollow obturator filling the defect. In all FRC-FPD models, the FRC framework showed stress-bearing capacity for the FPD. A fiber framework of the pontic was designed with three variations: with the main framework curved labially (FRC1), located in the center (FRC2), or curved lingually (FRC3). The Standard Abbreviation (ISO4) of International Journal of Prosthodontics is “Int J Prosthodont”.ISO 4 (Information and documentation – Rules for the abbreviation of title words and titles of publications) is an international standard, defining a uniform system for the abbreviation of serial publication titles.

The purpose of this study was to investigate the distribution of shades selected for metal ceramic crowns provided at a dental teaching hospital. The bone loss was of the same magnitude as in other studies on Brånemark implants as support for single crowns. These results suggest that it may be possible to place a resin-bonded prosthesis on an abutment tooth that has been restored using a spherical amalgam alloy. Twenty-eight total implants (diameter: 3.8 to 5.0 mm) were placed. Of the 269 impressions evaluated, 93.7% were clinically acceptable and showed complete reproduction of the preparation finish line; 17.5% showed small defects but the impressions were still rated clinically acceptable and categorized as Criteria II. Reasons for failure included abutment fracture (4), loosening with or without caries (18), secondary caries (9), fracture of prosthesis (2), fracture of extension (1), periodontal problems (6), and apical reaction (1). There was no difference in removal frequency between fixed partial dentures with moderate cantilever extensions and those with end-supported extensions. Mucosal hyperplasia and inflammation showed a trend of higher frequency at implants in the early group of patients (P > .05). A total of 8 crowns was remade following prosthetic complications; otherwise, the frequency of adverse events was low. They were placed on your computer when you launched this website. The information was imported to and combined in the 3Shape Implant Studio software for guided implant surgery planning. Auricular implants showed the highest survival rate (95%), and orbital implants showed the lowest survival rate (53%). Panoramic radiographs from 271 patients who were edentulous in one or both arches were evaluated for the presence of retained root fragments, impacted teeth, foreign bodies, radiolucencies, radiopacities, mental foramina at or near the crest of the residual alveolar ridge, and maxillary sinus proximity to the crest of the residual alveolar ridge. Data of interest were retrieved retrospectively, compared, and statistically analyzed using Chi-squared tests. ICP Newsletter - September 2020. There were 259 implants placed in 183 patients with a mean age of 29.8 years; 230 (89%) were placed in the maxilla and 29 (11%) were placed in the mandible. The type of amalgam and the brand of aluminum oxide affected the bond strength of the resin to amalgam alloy. Complete treatment and follow-up records of 1,037 CCs (60.5% women/39.5% men; age range: 18 to 82 years), 134 3uFDPs (59.2% women/40.8% men; age range: 33.6 to 93.6 years), and 322 FDPs (62.1% women/37.9% men; age range: 33.6 to 94.2 years) were available for analysis. For the surviving restorations, the improved PI over time was statistically significant (P = .001). The prosthesis length ratio and the crown length-bone ratio did not influence the failure rate. The aim of the study was to evaluate AllCeram crowns in dental practice over a 5- to 10.5-year period. One hundred thirty-seven cantilevered fixed partial dentures made between 1974 and 1990 were clinically and radiographically evaluated. MMT decreased by 17% during denture abstention following repeated implant surgery, and returned to 100% during the 12 months with the mandibular IOD. Within the limitations of the protocol of this study, the minimum number of measurements required to ensure relevant results for gap analysis was 18 for experimental and 90 for custom-made crowns. Mean bone loss was comparable for the early and late groups during the 5 years of follow-up (0.5 ± 0.46 and 0.7 ± 0.76 mm, respectively), but more patients presented at least 1 implant with more than 2 mm of bone loss during the follow-up period in the late group (P < .05). The main reason for failure was fracture of the ceramic (33.68%). A Siroflow abrasion unit was used to treat four groups of ten specimens that were subjected to 5, 10, 20, and 40 seconds of abrasion respectively. An International Survey among Prosthodontists of the Use of Mandibular Implant‐Supported Dental Prostheses. No fractures or chipping of the restorations occurred within the course of the evaluation. The minimum number of gap measurements required to produce relevant results for gap analysis was also investigated. Two methods were used to determine survival rates: (1) the percentage of the total exposed implants that survived was determined, and (2) life table analysis was used to calculate cumulative survival rates at different time intervals. The relationship between age versus irreversible complications for the fixed prosthetic restorations was statistically significant for all test groups. Osseointegration has influenced the decision-making process in prosthodontic treatments related to extraction. The patients with the failing restorations (66.2 years; mean range: 64.8 to 67.5 years) were 4.5 to 5.5 years older at initial treatment than the patients with the surviving restorations (61.3 years; mean range: 59.5 to 63.0 years). It has recently developed a long-range plan to become the most prestigious Asian journal of dental research regarding all aspects of oral and occlusal rehabilitation, fixed/removable prosthodontics, oral implantology and applied oral biology and physiology. Longer observation periods are necessary before this type of restorative design can be recommended as a general conservative procedure. This was the first documented study to use the SCL-90-R and CES-D scales on patients with suspected psychogenic dental prosthesis incompatibility with nonadaptation 6 months after incorporation. He has lived a normal family life and finished his university education. The results were similar to those for complete and partial osseointegrated prostheses. The ability to displace gingiva was indirectly measured by the quality of the final impression. This study evaluated the marginal fit of experimental and custom-made fixed prosthetic restorations through a new 360-degree external examination. For further information, please contact Rachel Yehl at ryehl@prosthodontics.org. The majority (85%) of the fixed partial dentures were acrylic resin veneer-gold restorations; 15% were metal ceramic restorations. Knowledge of the distribution of shades selected for permanently luted metal ceramic crowns may be a useful adjunct in shade selection, particularly for the inexperienced operator. The patients' complaints with the restorations included taste disorders, odynophagia, pain sensations, and functional and esthetic dissatisfaction. Int J Prosthodont 2011;24:356-362. During this study period, 14 individuals died, leaving 138 fixed partial dentures to be examined. After 18 years, STE developed in the left posterior region of the mandible. Carious lesions were found on 4% of the abutment teeth. The international journal of prosthodontics.. [International College of Prosthodontist,;] Official Journal of the International College of Prosthodontists and the International Society for Maxillofacial Rehabilitation. Of the prosthetic restorations, 165 were all-ceramic (68%), 79 were metal-ceramic (31%), and 4 were gold-acrylic (1%). The study population was a mixture of periodontally affected and non-periodontally affected patients, which is comparable to the population group in a private practice. This study is the first to use oral stereognosis tests for patients with psychologically diagnosed psychogenic dental prosthesis incompatibility. These findings indicate that resin-based dental restorative materials release agents cytotoxic and genotoxic to fibroblasts. Dry test specimens and those stored in water for up to 180 weeks were tested with a 3-point loading apparatus. The International Journal of Prosthodontics; ISSN 0893-2174; EUR 246.00 We are using cookies to implement functions like login, shopping cart or language selection for this website. Data were obtained from patient charts. Two implants were lost as a result of suppuration caused by membrane exposure, while another was lost after loading. Purpose: To establish a complete digital workflow for the design and manufacture of sports mouthguards and to observe preliminary clinical effects. The most frequent finding (30.6%) was close approximation of the maxillary sinus to the crest of the ridge. The editors of the Journal of Prosthodontics are pleased to present this virtual issue on the latest technological advances in ceramics. The monthly publication features timely, original peer-reviewed articles on the newest techniques, dental materials, and research findings. The aim of this study was to evaluate a new gingival retraction system relative to clinical success for fixed dental restorations under various clinical conditions. Results: Altogether, 37 patients (20%) were lost to follow-up during the 5 years, and more patients were noncompliant in the late group (P < .05). Evidence-based dentistry 2006: Where are we? Purpose: The aim of this clinical retrospective study was to evaluate the survival and success rates of metal-ceramic fixed partial dentures (FPDs) made by dental students over an 18-year interval. The maxillary posterior teeth were then placed palatally to maximize occlusal contacts with the opposing mandibular teeth. When compared with the control group, patients with suspected psychogenic dental prosthesis incompatibility showed statistically significant differences in the CES-D cumulative values (P = .015) and the SCL-90-R values Global Severity Index (P = .024) and Positive Symptom Distress Index (P = .049). Mats Kronstrom DDS, Odont Dr, PhD; Gunnar E. Carlsson LDS, Odont Dr, PhD; Pages: e622-e626; First Published: 17 March 2017 Furthermore, shades in the reddish-grey range of hue were rarely chosen. First, the fossa of mandibular posterior teeth was positioned on the crest of the mandibular edentulous ridge. To gain more insight into the treatment strategies for edentulous patients with atrophic ridges, three groups of patients were evaluated: group 1, patients with atrophy of the mandible who needed preprosthetic surgery but who only received new dentures because surgery was contraindicated; group 2, patients in the same oral condition as those in group 1 who were treated with vestibuloplasty and lowering of the floor of the mouth before fabrication of new dentures; group 3, the control group of patients without residual ridge-related problems who were treated with new complete dentures. The results indicate that the most frequently chosen shades were in the mid-range of reddish-brown hue. The diagnosis of psychogenic prosthesis incompatibility by the SCL-90-R and CES-D scales is affirmed by the lack of correlations between the functional/anatomic aspects of oral stereognostic ability, psychologic diagnostic tools, and the clinical picture of psychogenic prosthesis incompatibility. ICP journal. Materials and methods: The 5-year prosthesis cumulative survival rate was 97.1% in the early group and 100.0% in the late group. During the study period, 35 implants failed to integrate, and the survival rate for all exposed implants was 80%. The selection of more than one shade for a crown ("mixed shades") was generally restricted to the maxillary anterior teeth. One cantilevered pontic needed adjustment on the incisal edge due to premature contacts after the 3-year recall examination. The study population included 106 (35.1%) individuals diagnosed with bruxism. Included in this study were all patients who received implant-retained prostheses for auricular, nasal, or orbital defects from 1987 to 2001 in the Maxillofacial Clinics at the UCLA and City of Hope Medical Centers. All-ceramic restorations offer a predictable and successful restoration with an estimated survival probability of 93.5% over 10 years. Scanning electron micrographs showed smear layer removal as an immediate effect of air polishing. Post hoc analysis revealed that after the storage of 4 weeks no statistically significant reduction occurred. Editor-in-Chief: George A. Zarb Official journal of the International College of Prosthodontists, International Society for Maxillofacial Rehabilitation, German Society for Prosthodontics and Dental Materials Science, and Italian Academy of Prosthetic Dentistry Volume 26, 2013 Subscription Rates (Includes free Web access to all back issues) Conclusion: Following removal of a rare tumor, a young man was treated with gold crowns on three molars and a metal-ceramic crown on a first premolar, with attachments in the areas facing the defect for esthetic reasons. The stability of the mandibular dentures as well as the retention were better in group 2 than were those in group 1. By 1995 there was a threefold increase in both the number of patients and the number of implants placed per year. ACP members must be logged in to access the Journal.. The estimated survival rate was 97.3% after 5 years, 93.5% at 10 years, and 78.5% at 20 years. The patients in the test group expressed clear dissatisfaction with their dentures. There was no relationship between gender and irreversible complications. Endodontic complications on abutment teeth were more frequent in the mandible than in the maxillae. Bio-Oss was filled under the elevated sinus membrane using a dedicated instrument. Ceramics in Prosthodontics. Patients in the late group presented fewer problems with diction and veneer fractures, and fewer patients had their prostheses temporarily removed for adjustments (P < .05). A number of statistically significant differences was apparent between these 2 periods. EndNote Styles - International Journal of Prosthodontics. The results have direct implications on socioeconomic and forensic consequences for diagnosis and treatment by a dental clinician. The International Journal of Prosthodontics is dedicated to exploring and developing this conceptual shift in the role of today's prosthodontist, clinician, and educator alike. There were 3 implant failures registered, one before loading and one during the first year in function; one implant fractured after 6 years in service, giving a cumulative success rate for implants of 98.3%. The remaining 2 lost implants were managed by converting the distal unit of the fixed partial prosthesis to a cantilever. Both groups were followed and evaluated clinically and radiographically for 5 years according to similar protocols. Failures occurred significantly more when endodontically treated abutments were used. SCOPE.

Provides the worldwide dental community with current, scientifically sound information on patient care, research, and education in prosthodontics and interrelated disciplines. Base metal alloys, silicoating, mesh retention, and immobile abutments were positive factors. Computed tomography showed the bone graft distributing evenly around implants. Author(s): International College of Prosthodontists. More mandibular restorations failed than did maxillary units, but the difference was not significant. This study confirms the favorable results presented in other studies on Brånemark implants to support single-tooth restorations. The resistance against dislodgment of the denture was low in all three groups. Sixty-seven screw-type standard, self-tapping implants and mini-implants were placed. Implant Treatment with Fixed Prostheses in the Edentulous Maxilla. The use of a water balloon to elevate the sinus membrane is a truly minimally invasive technique and is associated with very little discomfort. The less favorable long-term survival of implants in the orbital rim, especially at irradiated sites, requires further study. The life table analysis demonstrated a cumulative 6-year survival rate of 92% for auricular implants and 87% for piriform/nasal implants. Materials and Methods: Fifty-seven patients with 82 FPDs from an original group of 104 patients with 128 FPDs attended an approximate clinical 18-year follow-up examination. Patients receiving artificial crowns and fixed partial dentures at a prosthodontic clinic were examined 18 to 23 years after treatment. Using the SCL-90-R and CES-D, it was possible to make a reliable initial diagnosis of the psychosomatic clinical situation regarding psychogenic prosthesis incompatibility. Multiunit resin-bonded fixed partial dentures had a smaller probability of survival than three-unit resin-bonded fixed partial dentures. The aim of this study was to investigate the optimal design of a fiber-reinforced composite (FRC) framework to obtain the maximum reinforcement for fixed partial dentures (FPDs) under three different loading conditions using three-dimensional finite element (FE) analysis. In contrast to other reports in the literature, retentive abutment preparation did not result in a higher survival rate than unprepared abutments. This case suggests that muscle bulk may be related to denture function. The editorial board is composed of a distinguished team of leading international scholars. The mean observation time was 102 ± 60 months. Group 2 patients scored comparably or higher than the normal ridge group (group 3). Patients were offered a supportive maintenance program. Number of restoration failures and reasons for failure were recorded. A total of 163 fixed partial dentures were inserted. This study aimed to investigate the occurrence of subpontic tissue enlargement (STE) beneath a mandibular fixed partial denture. Patients with a high CPITN at baseline had a 3.8 times greater likelihood of losing a complete crown (and abutment tooth) than patients with a low CPITN.

The International Journal of Prosthodontics is dedicated to exploring and developing this conceptual shift in the role of today's prosthodontist, clinician, and educator alike. The use of digital surface scanners with surgical planning software allows for the combination of the radiographic, prosthetic, surgical, and laboratory fields under a common virtual scenario, permitting complete digital treatment planning. From a list of discharged patients treated from 1975 to 1976 by undergraduate students at a dental school, 101 were recalled for free clinical examinations after 6, 11, and 18 years. There is a trend toward implanting younger patients for partial implant-supported reconstructions using more regenerative procedures and with a more equal distribution in the maxilla and mandible. http://www.quintpub.com/journals/ijp/gp.php?journal_name=IJP&name_abbr=IJP, Clinical long-term evaluation and failure characteristics of 1,335 all-ceramic restorations, Procera AllCeram Crowns Followed for 5 to 10.5 Years: A Prospective Clinical Study, 11-Year Follow-up Study of Resin-Bonded Fixed Partial Dentures, In vitro assessment of cytotoxicity of resin-based dental restorative materials on WEHI 13 Var fibroblasts, Implant-Retained Prostheses for Facial Defects: An Up to 14-Year Follow-up Report on the Survival Rates of Implants at UCLA, Short (8-mm) dental implants in the rehabilitation of partial and complete edentulism: A 3- to 14-year longitudinal study, Prosthetic restoration following removal of chondrosarcoma in the premaxillary region: A case presentation and follow-up for 16 years, Survival of complete crowns and periodontal health: 18-year retrospective study, A Study of Fixed Prosthodontics Performed at a University Clinic 18 Years after Insertion, 18-Year longitudinal study of cantilevered fixed restorations, Subpontic Tissue Enlargement of the Mandible Following Cross-Arch Fixed Partial Denture Reconstruction: An 18-Year Follow-up, Artificial crowns and fixed partial dentures 18 to 23 years after placement, An 18-Year Retrospective Analysis of Treatment Outcomes with Metal-Ceramic Fixed Partial Dentures, The influence of gender and age on fixed prosthetic restoration longevity: An up to 18- to 20-year follow-up in an undergraduate clinic, Effect of 180-Week Water Storage on the Flexural Properties of E-Glass and Silica Fiber Acrylic Resin Composite.

This method addresses functional considerations with the inner aspect of teeth and esthetic considerations with acrylic resin tooth veneers. The International Journal of Prosthodontics' journal/conference profile on Publons, with 77 reviews by 17 reviewers - working with reviewers, publishers, institutions, and funding agencies to turn peer review into a measurable research output. In relation to complete crown survival, caution is needed in patients with a high CPITN at baseline. The aim of this pilot study was to evaluate and determine psychogenic aspects of prosthesis incompatibility by psychologic tests that define the (psychogenic) prosthesis incompatibility as a psychologic disorder. The editorial board is composed of a distinguished team of leading international scholars. Small restorations in the bonding area did not affect the survival. It was concluded that airborne particle abrasion removes the smear layer, and the amount of dentin removed corresponded to the time of application. Finally, acrylic resin tooth veneers were attached on the buccal surface of posterior maxillary teeth to improve the arch discrepancy. The patient has kept up with his oral hygiene, using conventional methods for the teeth and prosthesis, with periodic flushing with chlorhexidine solution. Anyone who wants to read the articles should pay by individual or institution to access the articles. Tumedei, Margherita et al. With respect to the type of superstructures, there was a strong increase in the number of single-tooth replacements (from 4% to 23%). Application times of longer than 5 seconds showed obstruction of dentinal tubule openings, possibly a result of abrasive powder residue. The precision obtained with the custom-made crowns differed from that of the experimental specimens. The International Journal of Prosthodontics is dedicated to exploring and developing this conceptual shift in the role of today's prosthodontist, clinician, and educator alike. Altogether, 37 patients (20%) were lost to follow-up over 5 years; more patients were noncompliant in the late group (P < .05). The main causes for removal included caries, periodontitis, root fracture, and endodontic complications. Major changes in oral implantology treatments were noticed between the 1990* and 1995 periods at ACTA. Adaptation problems were ruled out as a possible cause. Latest issue: Issue 6/2020. Results: Known among international researchers, academics, and clinicians for its thorough and extensive review procedures, this journal continues to process articles as quickly as possible in keeping with its goal to present "news - not history." The primary indications of the 264 patients treated were trauma and aplasia. This could possibly be attributed to a more bioactive implant surface and shorter healing period before implant surgery in the late group. Generally, those abutment teeth that had been removed during the observation period had received previous endodontic treatment before restorations had been placed. The restoration has served the patient for 16 years, seemingly without discomfort, and it has not required any maintenance. A lateral load was applied to the three different loading points of the pontic 0 mm, 3 mm, and 6 mm from the incisal edge, each representing loading conditions 1, 2, and 3, respectively. In the edentulous group, the majority of superstructures in 1990 was fixed prostheses (64%), whereas in 1995 the majority was overdentures (71%). The Journal of Prosthodontics is the official journal of the American College of Prosthodontists.It promotes the advanced study and practice of prosthodontics, implant, esthetic, and reconstructive dentistry. The higher failure rate was related not only to periodontal disease, but also to a wide range of biologic and technical problems. Biologic and technical complications as well as patient satisfaction were recorded. No patient complained of food impaction. The use of osseointegrated implants is an accepted procedure for the treatment of total and partial edentulism and offers good predictability of long-term success. A dental history questionnaire was used to evaluate whether the patients had adapted to their dentures 6 months after incorporation. The present report describes a relatively simple but effective prosthodontic treatment following removal of a moderately well differentiated osteogenic chondrosarcoma in the premaxillary region.

The association between gender versus irreversible complications for the CCs (P = .481), 3uFDPs (P= .814), and FDPs (P = .410) groups was not statistically significant. This study presents a method of using shadow-speckle correlation to reconstruct a 3-dimensional (3D) tooth model. The marginal fit of six experimental and eight custom-made crowns was observed microscopically by means of a mechanical device, and software was employed to measure the gap. Postoperative patient reactions including swelling, discoloration, discomfort, hematomas, and disability were recorded. Localized high stress concentration was observed around the connectors under all loading conditions. Conclusion: Materials and Methods: The two groups of patients comprised 76 and 109 edentulous patients consecutively provided with 450 and 670 Branemark System implants and fixed screw-retained prostheses, respectively. A total of 1,037 complete crowns made in an undergraduate clinic for 456 patients were evaluated over an 18-year period. Significantly increased failure rates are associated with bruxism, nonvital teeth, and specific cementation agents. Purpose: Continuous, woven, silanized E-glass fibers and woven silica fibers were used to reinforce heat-cured and autopolymerized denture base polymers. The mean follow-up was 15.9 +/- 2.94 months. The mean inflated balloon volume was 0.67 +/- 0.17 mL and radiographic examination showed the mean elevated height by balloon to be 10.9 +/- 2.06 mm. Technical problems recorded included loss of cementation, fractures in the metal framework, and need for placement of a dowel in an abutment tooth.

[International College of Prosthodontists. In general, the soft tissue conditions around the restorations were healthy and comparable to those of the patients' natural teeth. Different all-ceramic restorations (crowns [n = 470], veneers [n = 318], onlays [n = 213], and inlays ]n = 334[) were placed in 302 patients (120 men, 182 women) between 1987 and 2009 at Medical University Innsbruck, Innsbruck, Austria. International Journal of Prosthodontics is a Subscription-based (non-OA) Journal. During the 18 years, 41 (30%) failed. The aim of this study was to report and compare the treatment outcomes of two patient cohorts from the same clinic, rehabilitated with fixed implant prostheses in the edentulous maxilla between 1986 and 1987 (early) and 2001 to 2004 (late). The most common clinical findings were gingival bleeding on probing and appearance of supragingival crown margins. The study cohort comprised 83 patients with complete dentures fabricated according to a standardized protocol. A total of 26 implants were placed. The outcome is also in agreement with that reported for metal-ceramic crowns. Preparation finish line with respect to the crest of the marginal gingiva (Level I through III) and type of preparation finish line (ie, shoulder or beveled) were recorded. ...

Comparison of the results expressed with the fuzzy function between 1995 and 2000 showed that indications for extraction have expanded with the prevalence of osseointegration concepts. Preliminary Clinical Application of Complete Workflow of Digitally Designed and Manufactured Sports Mouthguards. Over the last decade, oral implantology has become a major treatment modality to aid the restoration of reduced dentitions. The problem-free use of the appliance can be at least partly explained by the patient taking oral hygiene measures seriously from the beginning. Receiver operating characteristic analysis for all study groups revealed that for age, no clear cutoff point exists with acceptable specificity and sensitivity. Clinical examination was performed during patients' regularly scheduled maintenance appointments. The majority of the reduction occurred during 4 weeks of storage in water and remained approximately at that level for 180 weeks. The objective of this study was to assess the efficacy and safety of a minimally invasive sinus lift using an inflatable water balloon followed by bone grafting and implant placement. By 1995, the new technique of guided bone regeneration (GBR) using membranes was evidenced (no GBR in 1990* vs 33% of all patients in 1995 receiving some form of local GBR therapy). Over a 14-year period, 129 patients (68 women and 61 men) were consecutively treated with a fixed prosthesis (single or multiunit, screw or cement retained) supported by 265 different-sized implants (154 standard 10-mm; 111 shorter 8-mm). This report explains how relatively uncomplicated prosthodontic measures can enormously affect quality of life. Bleeding was somewhat more often recorded at teeth with AllCeram crowns (39%) than at contralateral teeth (27%). The main purpose of this retrospective study was to investigate the clinical outcome of the treatment with 259 consecutively placed Brånemark system implant-supported single crowns. The use of one cantilever extension unit had not negatively influenced the results for the fixed partial dentures. DNA gel electrophoresis was performed to detect possible genotoxicity and DNA damage. Within the limits of the study design and observation period, a mix of implant sizes did not appear to compromise the effectiveness of implant therapy in this particular population group. It was presumed that biomechanical loading in the mandible, along with other factors, might have caused the STE in this particular patient. Analysis of the data showed that casting alloy, pretreatment of the bonding surfaces, luting agent, and mobility of the abutment teeth were decisive prognostic factors for success. This study investigated the effect of airborne particle abrasion on the exposed dentin surfaces of 40 extracted teeth. Although carefully collected, accuracy cannot be guaranteed. Median duration was 84 +/- 3.6 months. Endodontic treatment was performed for a low number (2%) of the AllCeram crowns. The reproduction of the preparation finish line and an absence of bubbles or voids (Criteria I through III) were assesed. Further, the definition of poor bone quality has changed. Although submissions are welcome, please note that the COVID-19 pandemic has affected the processing and review times for new manuscripts, and so the submission process may take longer than normal. The aim of this study was to report and compare the prosthetic treatment outcomes from two patient cohorts provided with fixed implant prostheses in the edentulous maxilla between 1986 and 1987 (early) and 2001 to 2004 (late) at the same clinic. Twelve patients with suspected psychogenic prosthesis incompatibility and a group of 24 randomly selected control subjects were evaluated by application of the psychologic tests Symptom Checklist-90-R (SCL-90-R) and the Center of Epidemiological Studies Depression Scale (CES-D). The objective of this study was to use an oral stereognosis test to evaluate possible intraoral/sensorimotor causes in patients with a psychologic diagnosis of psychogenic prosthesis incompatibility, and to evaluate possible correlations between oral stereognosis and the psychologic diagnostic tools Symptom Checklist-90-R (SCL-90-R) and Center of Epidemiological Studies Depression Scale (CES-D). Including the rebonded restorations, the survival rate calculated using the Kaplan-Meier method was 76% after 5 years and 60% after 10 years. The aim of this study was to quantify the frequency of positive radiographic findings in edentulous arches. The Community Periodontal Index for Treatment Needs (CPITN) was calculated per sextant in a full-mouth assessment. Implant site preparation employed a pilot drill and osteotomy followed by water balloon elevation. Two hundred sixty-nine abutment teeth were evaluated. The present study monitored and quantified changes within a 5-year interval (1989-1991 [denoted as 1990*] to 1995) in the provision of different types of implant-supported superstructures and characteristics of recipient patients at the Academic Centre for Dentistry Amsterdam (ACTA). No significant differences were found for type of restoration and distribution in the mouth. However, when there were deep subgingival margins and a beveled preparation, the material was less effective than the single cord retraction technique. The FRC1 framework also best reduced displacement of the framework. This case report describes and evaluates a method of arranging artificial teeth in patients with an abnormal jaw relationship in which a wider maxillary arch opposes a narrower mandibular arch. Six of the 8 lost implants required implant replacement after the host sites' healing period. This is a report on Procera AllCeram crowns in a prospective multicenter study. There was a 2.3-times greater risk of failure associated with existing parafunction (bruxism, P = .0045). Anyone who wants to use the articles in any way must obtain permission from the publishers.

The aim of this clinical retrospective study was to evaluate the clinical quality, estimated survival rate, and failure analysis of different all-ceramic restorations in a long-term analysis of up to 20 years. Publishers own the rights to the articles in their journals. Latest issue: Issue 5/2020. This study aimed to evaluate the clinical effectiveness of different implant sizes (8- and 10-mm lengths with 3.75-, 4.1-, and 4.8-mm diameters) in diverse host bone sites in a selected sample of partially and completely edentulous patients. Conclusion: Prosthetic treatment and maintenance of implant-supported fixed prostheses improved significantly between the groups. The results showed that the surface areas of the patients in group 2 were approximately 180% greater in the vestibular region and were 126% greater in the sublingual region, compared with the other groups. Mean marginal bone loss and gingival crevice probing depth associated with either implant length were statistically comparable (P> .05). This case report describes the effect of complete denture abstention and subsequent rehabilitation with mandibular implant-supported overdentures (IOD) on masseter muscle thickness (MMT) in a 97-year-old patient. We are now at the center of another grand transformation… One of the principal technologies of this new mode of production and social organization is the Internet. Purpose: Implant treatment using osseointegrated implants has been performed for more than 40 years, but limited knowledge is available on how treatment outcomes have changed over time. The highest stress reduction ratio under all loading conditions was obtained using the FRC1 model. One major use of ISO 4 is to abbreviate the names of scientific journals.

After 5 and 10 years a cumulative survival rate of 97.7% and 93.5%, respectively, and a cumulative success rate of 97.7% and 92.2%, respectively, was recorded. No differences in survival rate were found for resin-bonded fixed partial dentures in the maxillae or mandible, or in the anterior and posterior regions. This case series study evaluated the clinical outcomes of cantilevered veneer-retained fixed partial dentures (VRFPDs) fabricated with IPS e.max Press for single-tooth replacement in the anterior arch. Results: Nine FPDs were lost because of extraction of an abutment tooth, and 1 FPD was removed for esthetic reasons. When the spherical alloy was air abraded using 60-microns aluminum oxide prior to cementation of a Rexillium rod using Panavia, the bond strength was not significantly different from the previously reported bond strengths of Panavia to etched enamel. The patients were evaluated at baseline and annually from October 2005 to July 2011 for the integrity of the VRFPDs, proximal contacts, occulsal relationships, pulp vitality, and tooth mobility. Successful sinus membrane water balloon lifting procedures were performed in 26 cases; two procedures were aborted due to sinus membrane perforation. Those statements are on file at the editorial office. International Journal of Periodontics & Restorative Dentistry. Dresden, 23-26 May 2002. For the last several years, this procedure has also been used for single-tooth replacement following loss of teeth for traumatic, periodontal, and carious lesions. The clinical performance of 325 resin-bonded fixed partial dentures (RBFPD) placed between 1984 and 1995 was reviewed. Part 1: Implants and Biologic Response in Two Patient Cohorts Restored Between 1986 and 1987 and 15 Years Later, Implant treatment with fixed prostheses in the edentulous maxilla. One implant was lost due to infection. Baseline bone height was 4.92 +/- 1.24 mm. Compared with other methods based on laser or optical geometric measurements, the shadow-speckle method overcomes their limitations by using a digital image correlation to reconstruct a 3D tooth model. The patients found the esthetics to be excellent. Data on the selection of shade for 2,500 metal ceramic crown units, placed over a 5-year period at the University Dental Hospital of Manchester, were collected and analyzed. Nonvital teeth showed a significantly higher risk of failure (P < .0001). The aim of this study was to determine the effect of long-term water immersion on the flexural properties of fiber-reinforced composite. Two types of implants were used (141 titanium plasma-sprayed and 124 Sand-blasted, large-grit, acid-etched). Twenty-five randomly selected Japanese dental clinicians in 1995 and 2005 with 5 to 15 years of clinical experience were requested to define bone support levels for prosthodontic treatment options. The degree of satisfaction was indicated with a visual analog scale. The success rate for the gold-resin restorations was less favorable: 43% remained unchanged and 33% had been removed. The results suggest that single-tooth replacement using osseointegrated implants provides predictable success. Twelve clinicians at nine clinics placed 87 crowns in 50 patients. China Hong-Chang Lai, DDS ... All members of the Journal of Prosthodontics Editorial Board and Editorial Review Board have been asked to sign Conflict of Interest disclosure statements. A total of 207 implants were placed in 72 patients, and 182 implants had been uncovered. Severe morphologic alterations and pronounced DNA damage were also observed.

Prosthetic treatment was performed using significantly less chair time in the late group (P < .05), and 22 and 68 patients were followed for 5 years without any reported complications in the early and late groups, respectively (P < .05). The early group included 76 edentulous patients who were consecutively provided with 450 turned Branemark System implants; the late group included 109 edentulous patients provided with 360 turned and 310 TiUnite Branemark System implants. Other Titles: Title Abbreviation: Int J Prosthodont Title(s): The International journal of prosthodontics. PI and BOP were not directly related to the frequency of failures. Conclusion: This 18-year follow-up of metal-ceramic FPDs in just over half of the originally treated patient group was associated with good patient satisfaction and few biologic and technical complications. Six crowns (7%) were recorded as failures; five of these crowns (6%) had to be remade. A total of 9 patients (10 implants) was lost to follow-up. One or more of these radiographic observations were found in 51.7% of the examined films. During a mean observation time of 46.57 months, 35 VRFPDs on vital abutment teeth did not exhibit postoperative sensitivity or secondary caries. Some of the AllCeram crowns were among the very first that were placed. No correlation was found between oral stereognostic ability and the SCL-90-R or CES-D values. 1 (23.12.2019) Page 99-104, doi:10.11607/ijp.6348, PubMed:31860919 Preliminary Clinical Application of Complete Workflow of Digitally Designed and … The mean inflated balloon volume was 0.67 +/- 0.17 mL. It is possible to achieve high survival rates of implants in the auricular and piriform/nasal sites through careful presurgical and radiographic planning. International journal of prosthodontics (GYFmHBV)099227436: Material Type: Periodical: Document Type: Journal / Magazine / Newspaper: ISSN: 0893-2174: OCLC Number: 614360530: Notes: Zusatz bis 19.2006: Official journal of International College of Prosthodontists, International Society of Maxillofacial Rehabilitation. Each framework was compared with a hybrid composite FPD without any fiber reinforcement (C-FPD). EndNote Styles - International Journal of Prosthodontics. Int J Prosthodont 2010;23:243-245. Only 6.3% of the impressions were unacceptable and categorized as Criteria III. The aim of this study was to assess the cytotoxicity of 4 resin composites' eluates on WEHI 13 Var fibroblasts as they aged in a biologic medium. An analysis of retrospective data was conducted to establish the survival rates of osseointegrated implants used to retain orbital, nasal, and auricular prostheses over a 14-year period and to recommend guidelines in the restorative treatment of such facial defects. This study investigated the survival of complete crowns in relation to periodontal variables on a long-term basis. The long-term results were good, especially for the metal ceramic restorations: 79% remained unchanged and only 3% had been removed. Pre- and postoperative panoramic films or computed tomographs (optional) were taken for every case to measure and compare the results of the sinus membrane lift using a water balloon. The differences between the three groups were evaluated 6.5 years after treatment. All patients who received oral implants in 1990* and in 1995 were selected, and their files (95 and 105, respectively) were consulted. Int J Prosthodont 2011;24:345-355. Thus, psychogenic prosthesis incompatibility can be classified more explicitly as a psychosomatic disorder. In cases of epigingival and subgingival (< 2 mm) preparation margins, MFC was a less traumatic alternative method of gingival retraction. Prosthetic work should be preceded by periodontal examination and prophylactic and periodontal treatment if needed. Journal of Prosthodontic Research originated as an official journal of Japan Prosthodontic Society. The 14-year cumulative survival rates for all short and standard implants were 97.9% and 97.1%, respectively. A surgical guide was obtained by a 3D printer, and the surgical procedure was done using the Biohorizons Guided Surgery Kit and its protocol. Survival rates were 92.3% and 95.9% for titanium plasma-sprayed short and standard implants, respectively, and 100% and 98.5% for the Sand-blasted, large-grit, acid-etched short and standard implants, respectively. Read more. Periodontal variables were measured, including Plaque Index (PI), bleeding on probing (BOP), probing pocket depth (PPD), and attachment level. MMT was measured bilaterally using an ultrasound scanner during 1 year of wearing a conventional denture, after 101 days of voluntary denture abstention, and 3, 6, and 12 months after delivery of the IOD. The Journal of Prosthodontics promotes the advanced study, science, and practice of prosthodontics, implant, esthetic, and reconstructive dentistry.It is the official journal of the American College of Prosthodontists, the association that represents the dental specialty of prosthodontics. The 5-year overall implant cumulative survival rates were 93.4% and 97.3% for the early and late groups, respectively. Both groups were followed for 5 years with regard to prosthetic treatment, clinical maintenance, and complications. Data provided are for informational purposes only. The overall success rate of cantilever fixed prostheses was 70% over a period of 18 years. Implant treatment has been performed for more than 45 years, but there is still limited knowledge on how treatment outcomes are changing over time. Control specimens were unreinforced. Catch up on the latest ICP News! Esthetic match, porcelain surface, marginal discoloration, and integrity were evaluated following modified California Dental Association/Ryge criteria. This study obtained information on the long-term efficiency of prosthetic rehabilitation with fixed partial dentures performed by undergraduate students. The results of this study demonstrate about the same clinical outcome as has been reported by similar studies on all-ceramic crowns built on a core of alumina. INTERNATIONAL. A 55-year-old Japanese woman received periodontal therapy and cross-arch fixed partial dentures were placed in the maxilla and mandible. ICP Biennial Meeting. In the early group, significantly more turned implants failed before prosthesis insertion compared to the outcome of TiUnite implants in the late group (P < .05). Furthermore we use Google Analytics to create anonymized statistical reports of the usage which creates Cookies too. Fibers were oriented at a 45-degree angle to the long axis of the test specimens. Implant treatment was more predictable before loading in the late group of patients, related to the change in the implant surface (P < .05). Dropouts were recorded for 23 patients with 23 prostheses supported by 42 implants. Welcome to THE INTERNATIONAL JOURNAL OF PROSTHODONTICS's online manuscript submission and peer-review system Thank you for submitting to IJP! Two hundred eighty-three of the resin-bonded fixed partial dentures were primary restorations, and 42 of the restorations were secondary and tertiary after the loss of the primary resin-bonded fixed partial denture. Cementation using Variolink showed significantly fewer failures than Optec Cement (P = .0217) and Dual Cement (P = .0099). Cantilevered IPS e.max Press VRFPDs should be considered a minimally invasive, single-tooth restorative strategy in the anterior or first premolar area. The International Journal of Oral & Maxillofacial Implants (40) The International Journal of Periodontics & Restorative Dentistry (32) The International Journal of Prosthodontics (33) Thematic Abstract Review (4) What's New (98) Fewer metal ceramic restorations than acrylic resin veneer-gold restorations were removed. Thirty-three of the prostheses were located in the mandible (11 in the anterior and 22 in the posterior region) and 104 were located in the maxillae (58 anterior prostheses and 46 posterior prostheses). The results revealed no significant differences in oral stereognostic ability between patients with diagnosed psychogenic dental prosthesis incompatibility and the control patients. The International Journal of Prosthodontics. Statistical analysis (Spearman Rank Order) showed a significant difference between all groups (P < .05) but not within groups (P > .05). The study cohort comprised 83 patients with complete dentures fabricated according to a standardized protocol. In this article, the authors present a clinical case in which a guided implant surgery was performed based on a complete digital surgical plan combining the information from a cone beam computed tomography scan and the virtual simulation obtained from the 3Shape TRIOS intraoral surface scanner. The International Journal of Prosthodontics > 2017-01-14 The International Journal of Prosthodontics Follow New on 2017 Jan 14: Survey of Dental Materials Used by Dentists for Indirect Restorations in Saudi Arabia Y Haider et al. Caries was the most frequent reason for failure, followed by periodontal disease. The California Dental Association quality evaluation system was used for assessment of marginal integrity and esthetics. A significant influence on the quality of the impressions was found when the preparation finish line was more than 2 mm subgingivally for shoulder (P < .004) as well as beveled preparations (P < .004). The Journal of Prosthetic Dentistry is the leading professional journal devoted exclusively to prosthetic and restorative dentistry.The Journal is the official publication for 24 leading U.S. international prosthodontic organizations. Only those crowns placed adjacent to minimally restored vital teeth were included in the study. Page 487-492, doi:10.11607/ijp.6470, PubMed:32956429 Perceptibility and Acceptability of Color Differences of Single-Tooth Implants at the Restoration … Odds ratios were 1.00 for both PI and BOP. Also, in 1995 more maxillae were implanted than in 1990* (44% vs 26%). In contrast, the survival rate for orbital implants showed a steady downward trend and reached 59% at 66 months. Differences in fit between experimental specimens and custom-made ones showed that experimental results might not always be obtained in clinical practice. The results indicate a good prognosis for Procera AllCeram crowns also for posterior teeth. In the remaining 106 patients (223 implants), 8 implants failed (4 standard and 4 shorter), in type 3 or 4 bone. The patient group of < or = 40 years of age had significantly increased, from 7% to 23%. The mean follow-up period was 17.7 years (range: 17.1 to 21.3 years). A removable partial denture was retained by the attachments and conventional cast retentive circumferential clasps, including a hollow obturator filling the defect. In all FRC-FPD models, the FRC framework showed stress-bearing capacity for the FPD. A fiber framework of the pontic was designed with three variations: with the main framework curved labially (FRC1), located in the center (FRC2), or curved lingually (FRC3). The Standard Abbreviation (ISO4) of International Journal of Prosthodontics is “Int J Prosthodont”.ISO 4 (Information and documentation – Rules for the abbreviation of title words and titles of publications) is an international standard, defining a uniform system for the abbreviation of serial publication titles.

The purpose of this study was to investigate the distribution of shades selected for metal ceramic crowns provided at a dental teaching hospital. The bone loss was of the same magnitude as in other studies on Brånemark implants as support for single crowns. These results suggest that it may be possible to place a resin-bonded prosthesis on an abutment tooth that has been restored using a spherical amalgam alloy. Twenty-eight total implants (diameter: 3.8 to 5.0 mm) were placed. Of the 269 impressions evaluated, 93.7% were clinically acceptable and showed complete reproduction of the preparation finish line; 17.5% showed small defects but the impressions were still rated clinically acceptable and categorized as Criteria II. Reasons for failure included abutment fracture (4), loosening with or without caries (18), secondary caries (9), fracture of prosthesis (2), fracture of extension (1), periodontal problems (6), and apical reaction (1). There was no difference in removal frequency between fixed partial dentures with moderate cantilever extensions and those with end-supported extensions. Mucosal hyperplasia and inflammation showed a trend of higher frequency at implants in the early group of patients (P > .05). A total of 8 crowns was remade following prosthetic complications; otherwise, the frequency of adverse events was low. They were placed on your computer when you launched this website. The information was imported to and combined in the 3Shape Implant Studio software for guided implant surgery planning. Auricular implants showed the highest survival rate (95%), and orbital implants showed the lowest survival rate (53%). Panoramic radiographs from 271 patients who were edentulous in one or both arches were evaluated for the presence of retained root fragments, impacted teeth, foreign bodies, radiolucencies, radiopacities, mental foramina at or near the crest of the residual alveolar ridge, and maxillary sinus proximity to the crest of the residual alveolar ridge. Data of interest were retrieved retrospectively, compared, and statistically analyzed using Chi-squared tests. ICP Newsletter - September 2020. There were 259 implants placed in 183 patients with a mean age of 29.8 years; 230 (89%) were placed in the maxilla and 29 (11%) were placed in the mandible. The type of amalgam and the brand of aluminum oxide affected the bond strength of the resin to amalgam alloy. Complete treatment and follow-up records of 1,037 CCs (60.5% women/39.5% men; age range: 18 to 82 years), 134 3uFDPs (59.2% women/40.8% men; age range: 33.6 to 93.6 years), and 322 FDPs (62.1% women/37.9% men; age range: 33.6 to 94.2 years) were available for analysis. For the surviving restorations, the improved PI over time was statistically significant (P = .001). The prosthesis length ratio and the crown length-bone ratio did not influence the failure rate. The aim of the study was to evaluate AllCeram crowns in dental practice over a 5- to 10.5-year period. One hundred thirty-seven cantilevered fixed partial dentures made between 1974 and 1990 were clinically and radiographically evaluated. MMT decreased by 17% during denture abstention following repeated implant surgery, and returned to 100% during the 12 months with the mandibular IOD. Within the limitations of the protocol of this study, the minimum number of measurements required to ensure relevant results for gap analysis was 18 for experimental and 90 for custom-made crowns. Mean bone loss was comparable for the early and late groups during the 5 years of follow-up (0.5 ± 0.46 and 0.7 ± 0.76 mm, respectively), but more patients presented at least 1 implant with more than 2 mm of bone loss during the follow-up period in the late group (P < .05). The main reason for failure was fracture of the ceramic (33.68%). A Siroflow abrasion unit was used to treat four groups of ten specimens that were subjected to 5, 10, 20, and 40 seconds of abrasion respectively. An International Survey among Prosthodontists of the Use of Mandibular Implant‐Supported Dental Prostheses. No fractures or chipping of the restorations occurred within the course of the evaluation. The minimum number of gap measurements required to produce relevant results for gap analysis was also investigated. Two methods were used to determine survival rates: (1) the percentage of the total exposed implants that survived was determined, and (2) life table analysis was used to calculate cumulative survival rates at different time intervals. The relationship between age versus irreversible complications for the fixed prosthetic restorations was statistically significant for all test groups. Osseointegration has influenced the decision-making process in prosthodontic treatments related to extraction. The patients with the failing restorations (66.2 years; mean range: 64.8 to 67.5 years) were 4.5 to 5.5 years older at initial treatment than the patients with the surviving restorations (61.3 years; mean range: 59.5 to 63.0 years). It has recently developed a long-range plan to become the most prestigious Asian journal of dental research regarding all aspects of oral and occlusal rehabilitation, fixed/removable prosthodontics, oral implantology and applied oral biology and physiology. Longer observation periods are necessary before this type of restorative design can be recommended as a general conservative procedure. This was the first documented study to use the SCL-90-R and CES-D scales on patients with suspected psychogenic dental prosthesis incompatibility with nonadaptation 6 months after incorporation. He has lived a normal family life and finished his university education. The results were similar to those for complete and partial osseointegrated prostheses. The ability to displace gingiva was indirectly measured by the quality of the final impression. This study evaluated the marginal fit of experimental and custom-made fixed prosthetic restorations through a new 360-degree external examination. For further information, please contact Rachel Yehl at ryehl@prosthodontics.org. The majority (85%) of the fixed partial dentures were acrylic resin veneer-gold restorations; 15% were metal ceramic restorations. Knowledge of the distribution of shades selected for permanently luted metal ceramic crowns may be a useful adjunct in shade selection, particularly for the inexperienced operator. The patients' complaints with the restorations included taste disorders, odynophagia, pain sensations, and functional and esthetic dissatisfaction. Int J Prosthodont 2011;24:356-362. During this study period, 14 individuals died, leaving 138 fixed partial dentures to be examined. After 18 years, STE developed in the left posterior region of the mandible. Carious lesions were found on 4% of the abutment teeth. The international journal of prosthodontics.. [International College of Prosthodontist,;] Official Journal of the International College of Prosthodontists and the International Society for Maxillofacial Rehabilitation. Of the prosthetic restorations, 165 were all-ceramic (68%), 79 were metal-ceramic (31%), and 4 were gold-acrylic (1%). The study population was a mixture of periodontally affected and non-periodontally affected patients, which is comparable to the population group in a private practice. This study is the first to use oral stereognosis tests for patients with psychologically diagnosed psychogenic dental prosthesis incompatibility. These findings indicate that resin-based dental restorative materials release agents cytotoxic and genotoxic to fibroblasts. Dry test specimens and those stored in water for up to 180 weeks were tested with a 3-point loading apparatus.

Data were obtained from patient charts. Two implants were lost as a result of suppuration caused by membrane exposure, while another was lost after loading. Purpose: To establish a complete digital workflow for the design and manufacture of sports mouthguards and to observe preliminary clinical effects. The most frequent finding (30.6%) was close approximation of the maxillary sinus to the crest of the ridge. The editors of the Journal of Prosthodontics are pleased to present this virtual issue on the latest technological advances in ceramics. The monthly publication features timely, original peer-reviewed articles on the newest techniques, dental materials, and research findings. The aim of this study was to evaluate a new gingival retraction system relative to clinical success for fixed dental restorations under various clinical conditions. Results: Altogether, 37 patients (20%) were lost to follow-up during the 5 years, and more patients were noncompliant in the late group (P < .05). Evidence-based dentistry 2006: Where are we? Purpose: The aim of this clinical retrospective study was to evaluate the survival and success rates of metal-ceramic fixed partial dentures (FPDs) made by dental students over an 18-year interval. The maxillary posterior teeth were then placed palatally to maximize occlusal contacts with the opposing mandibular teeth. When compared with the control group, patients with suspected psychogenic dental prosthesis incompatibility showed statistically significant differences in the CES-D cumulative values (P = .015) and the SCL-90-R values Global Severity Index (P = .024) and Positive Symptom Distress Index (P = .049). Mats Kronstrom DDS, Odont Dr, PhD; Gunnar E. Carlsson LDS, Odont Dr, PhD; Pages: e622-e626; First Published: 17 March 2017 Furthermore, shades in the reddish-grey range of hue were rarely chosen. First, the fossa of mandibular posterior teeth was positioned on the crest of the mandibular edentulous ridge. To gain more insight into the treatment strategies for edentulous patients with atrophic ridges, three groups of patients were evaluated: group 1, patients with atrophy of the mandible who needed preprosthetic surgery but who only received new dentures because surgery was contraindicated; group 2, patients in the same oral condition as those in group 1 who were treated with vestibuloplasty and lowering of the floor of the mouth before fabrication of new dentures; group 3, the control group of patients without residual ridge-related problems who were treated with new complete dentures. The results indicate that the most frequently chosen shades were in the mid-range of reddish-brown hue. The diagnosis of psychogenic prosthesis incompatibility by the SCL-90-R and CES-D scales is affirmed by the lack of correlations between the functional/anatomic aspects of oral stereognostic ability, psychologic diagnostic tools, and the clinical picture of psychogenic prosthesis incompatibility. ICP journal. Materials and methods: The 5-year prosthesis cumulative survival rate was 97.1% in the early group and 100.0% in the late group. During the study period, 35 implants failed to integrate, and the survival rate for all exposed implants was 80%. The selection of more than one shade for a crown ("mixed shades") was generally restricted to the maxillary anterior teeth. One cantilevered pontic needed adjustment on the incisal edge due to premature contacts after the 3-year recall examination. The study population included 106 (35.1%) individuals diagnosed with bruxism. Included in this study were all patients who received implant-retained prostheses for auricular, nasal, or orbital defects from 1987 to 2001 in the Maxillofacial Clinics at the UCLA and City of Hope Medical Centers. All-ceramic restorations offer a predictable and successful restoration with an estimated survival probability of 93.5% over 10 years. Scanning electron micrographs showed smear layer removal as an immediate effect of air polishing. Post hoc analysis revealed that after the storage of 4 weeks no statistically significant reduction occurred. Editor-in-Chief: George A. Zarb Official journal of the International College of Prosthodontists, International Society for Maxillofacial Rehabilitation, German Society for Prosthodontics and Dental Materials Science, and Italian Academy of Prosthetic Dentistry Volume 26, 2013 Subscription Rates (Includes free Web access to all back issues) Conclusion: Following removal of a rare tumor, a young man was treated with gold crowns on three molars and a metal-ceramic crown on a first premolar, with attachments in the areas facing the defect for esthetic reasons. The stability of the mandibular dentures as well as the retention were better in group 2 than were those in group 1. By 1995 there was a threefold increase in both the number of patients and the number of implants placed per year. ACP members must be logged in to access the Journal.. The estimated survival rate was 97.3% after 5 years, 93.5% at 10 years, and 78.5% at 20 years. The patients in the test group expressed clear dissatisfaction with their dentures. There was no relationship between gender and irreversible complications. Endodontic complications on abutment teeth were more frequent in the mandible than in the maxillae. Bio-Oss was filled under the elevated sinus membrane using a dedicated instrument. Ceramics in Prosthodontics. Patients in the late group presented fewer problems with diction and veneer fractures, and fewer patients had their prostheses temporarily removed for adjustments (P < .05). A number of statistically significant differences was apparent between these 2 periods. EndNote Styles - International Journal of Prosthodontics. The results have direct implications on socioeconomic and forensic consequences for diagnosis and treatment by a dental clinician. The International Journal of Prosthodontics is dedicated to exploring and developing this conceptual shift in the role of today's prosthodontist, clinician, and educator alike. There were 3 implant failures registered, one before loading and one during the first year in function; one implant fractured after 6 years in service, giving a cumulative success rate for implants of 98.3%. The remaining 2 lost implants were managed by converting the distal unit of the fixed partial prosthesis to a cantilever. Both groups were followed and evaluated clinically and radiographically for 5 years according to similar protocols. Failures occurred significantly more when endodontically treated abutments were used. SCOPE.

Provides the worldwide dental community with current, scientifically sound information on patient care, research, and education in prosthodontics and interrelated disciplines. Base metal alloys, silicoating, mesh retention, and immobile abutments were positive factors. Computed tomography showed the bone graft distributing evenly around implants. Author(s): International College of Prosthodontists. More mandibular restorations failed than did maxillary units, but the difference was not significant. This study confirms the favorable results presented in other studies on Brånemark implants to support single-tooth restorations. The resistance against dislodgment of the denture was low in all three groups. Sixty-seven screw-type standard, self-tapping implants and mini-implants were placed. Implant Treatment with Fixed Prostheses in the Edentulous Maxilla. The use of a water balloon to elevate the sinus membrane is a truly minimally invasive technique and is associated with very little discomfort. The less favorable long-term survival of implants in the orbital rim, especially at irradiated sites, requires further study. The life table analysis demonstrated a cumulative 6-year survival rate of 92% for auricular implants and 87% for piriform/nasal implants. Materials and Methods: Fifty-seven patients with 82 FPDs from an original group of 104 patients with 128 FPDs attended an approximate clinical 18-year follow-up examination. Patients receiving artificial crowns and fixed partial dentures at a prosthodontic clinic were examined 18 to 23 years after treatment. Using the SCL-90-R and CES-D, it was possible to make a reliable initial diagnosis of the psychosomatic clinical situation regarding psychogenic prosthesis incompatibility. Multiunit resin-bonded fixed partial dentures had a smaller probability of survival than three-unit resin-bonded fixed partial dentures. The aim of this study was to investigate the optimal design of a fiber-reinforced composite (FRC) framework to obtain the maximum reinforcement for fixed partial dentures (FPDs) under three different loading conditions using three-dimensional finite element (FE) analysis. In contrast to other reports in the literature, retentive abutment preparation did not result in a higher survival rate than unprepared abutments. This case suggests that muscle bulk may be related to denture function. The editorial board is composed of a distinguished team of leading international scholars. The mean observation time was 102 ± 60 months. Group 2 patients scored comparably or higher than the normal ridge group (group 3). Patients were offered a supportive maintenance program. Number of restoration failures and reasons for failure were recorded. A total of 163 fixed partial dentures were inserted. This study aimed to investigate the occurrence of subpontic tissue enlargement (STE) beneath a mandibular fixed partial denture. Patients with a high CPITN at baseline had a 3.8 times greater likelihood of losing a complete crown (and abutment tooth) than patients with a low CPITN.

The International Journal of Prosthodontics is dedicated to exploring and developing this conceptual shift in the role of today's prosthodontist, clinician, and educator alike. The use of digital surface scanners with surgical planning software allows for the combination of the radiographic, prosthetic, surgical, and laboratory fields under a common virtual scenario, permitting complete digital treatment planning. From a list of discharged patients treated from 1975 to 1976 by undergraduate students at a dental school, 101 were recalled for free clinical examinations after 6, 11, and 18 years. There is a trend toward implanting younger patients for partial implant-supported reconstructions using more regenerative procedures and with a more equal distribution in the maxilla and mandible. http://www.quintpub.com/journals/ijp/gp.php?journal_name=IJP&name_abbr=IJP, Clinical long-term evaluation and failure characteristics of 1,335 all-ceramic restorations, Procera AllCeram Crowns Followed for 5 to 10.5 Years: A Prospective Clinical Study, 11-Year Follow-up Study of Resin-Bonded Fixed Partial Dentures, In vitro assessment of cytotoxicity of resin-based dental restorative materials on WEHI 13 Var fibroblasts, Implant-Retained Prostheses for Facial Defects: An Up to 14-Year Follow-up Report on the Survival Rates of Implants at UCLA, Short (8-mm) dental implants in the rehabilitation of partial and complete edentulism: A 3- to 14-year longitudinal study, Prosthetic restoration following removal of chondrosarcoma in the premaxillary region: A case presentation and follow-up for 16 years, Survival of complete crowns and periodontal health: 18-year retrospective study, A Study of Fixed Prosthodontics Performed at a University Clinic 18 Years after Insertion, 18-Year longitudinal study of cantilevered fixed restorations, Subpontic Tissue Enlargement of the Mandible Following Cross-Arch Fixed Partial Denture Reconstruction: An 18-Year Follow-up, Artificial crowns and fixed partial dentures 18 to 23 years after placement, An 18-Year Retrospective Analysis of Treatment Outcomes with Metal-Ceramic Fixed Partial Dentures, The influence of gender and age on fixed prosthetic restoration longevity: An up to 18- to 20-year follow-up in an undergraduate clinic, Effect of 180-Week Water Storage on the Flexural Properties of E-Glass and Silica Fiber Acrylic Resin Composite.
