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. Both groups were followed for 5 years with regard to prosthetic treatment, clinical maintenance, and complications. This study investigated the possible relationship between the survival of complete crowns (CCs), 3-unit fixed dental prostheses (3uFDPs), and fixed dental prostheses (FDPs) versus gender and age at initial treatment over a period of 18 to 20 years in an undergraduate clinic. Post hoc analysis revealed that after the storage of 4 weeks no statistically significant reduction occurred. 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. This case suggests that muscle bulk may be related to denture function. Biomechanical stress and microgap analysis of bone-level and tissue-level implant abutment structure according to the five different directions of occlusal loads 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. This study aimed to investigate the occurrence of subpontic tissue enlargement (STE) beneath a mandibular fixed partial denture. In cases of epigingival and subgingival (< 2 mm) preparation margins, MFC was a less traumatic alternative method of gingival retraction. Number of restoration failures and reasons for failure were recorded. 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. 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. For the CPITN, odds ratios were 3.00 to 3.83. INTERNATIONAL. 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 total of 207 implants were placed in 72 patients, and 182 implants had been uncovered. The International journal of prosthodontics | Citations: 3,491 | Official Journal of the International College of Prosthodontists and the International Society for Maxillofacial Rehabilitation. Fewer metal ceramic restorations than acrylic resin veneer-gold restorations were removed. This study suggests that the optimum design of an FRC framework is to labially curve the FRC of the main framework at the region of the pontic. SCOPE. The international journal of prosthodontics.. [International College of Prosthodontist,;] This is a report on Procera AllCeram crowns in a prospective multicenter study. Caries was the most frequent reason for failure, followed by periodontal disease. 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. The success rate for the gold-resin restorations was less favorable: 43% remained unchanged and 33% had been removed. A total of 163 fixed partial dentures were inserted. 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. 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. materials and methods: A three-unit FPD replacing the maxillary right lateral incisor was constructed using FE analysis software (ANSYS 10.0, ANSYS).

Auricular implants showed the highest survival rate (95%), and orbital implants showed the lowest survival rate (53%). 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. 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 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. Localized high stress concentration was observed around the connectors under all loading conditions. EndNote Styles - International Journal of Prosthodontics. 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 study cohort comprised 83 patients with complete dentures fabricated according to a standardized protocol. Valente, Nicola Alberto et al. 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). The minimum number of gap measurements required to produce relevant results for gap analysis was also investigated. Journal of Prosthodontic Research originated as an official journal of Japan Prosthodontic Society. No fractures or chipping of the restorations occurred within the course of the evaluation. The patients found the esthetics to be excellent. ;] 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). Differences in fit between experimental specimens and custom-made ones showed that experimental results might not always be obtained in clinical practice. The mean inflated balloon volume was 0.67 +/- 0.17 mL. Only those crowns placed adjacent to minimally restored vital teeth were included in the study. Only 6.3% of the impressions were unacceptable and categorized as Criteria III. The results suggest that single-tooth replacement using osseointegrated implants provides predictable success. Author Guidelines. 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). Cytotoxicity was determined by counting the number of viable cells by trypan blue exclusion. Two implants were lost as a result of suppuration caused by membrane exposure, while another was lost after loading. ICP Newsletter - September 2020. The Community Periodontal Index for Treatment Needs (CPITN) was calculated per sextant in a full-mouth assessment. 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. Patients were extremely pleased with the results and needed very little medical attention after surgery. The overall success rate of cantilever fixed prostheses was 70% over a period of 18 years. 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. This study obtained information on the long-term efficiency of prosthetic rehabilitation with fixed partial dentures performed by undergraduate students. Some of the AllCeram crowns were among the very first that were placed. Int J Prosthodont 33 (2020), No. The relationship between age versus irreversible complications for the fixed prosthetic restorations was statistically significant for all test groups. The results revealed no significant differences in oral stereognostic ability between patients with diagnosed psychogenic dental prosthesis incompatibility and the control patients. Severe morphologic alterations and pronounced DNA damage were also observed. 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. The aim of the study was to evaluate AllCeram crowns in dental practice over a 5- to 10.5-year period. It was presumed that biomechanical loading in the mandible, along with other factors, might have caused the STE in this particular patient. The results indicate that the most frequently chosen shades were in the mid-range of reddish-brown hue. Major changes in oral implantology treatments were noticed between the 1990* and 1995 periods at ACTA. ICP journal. The present report describes a relatively simple but effective prosthodontic treatment following removal of a moderately well differentiated osteogenic chondrosarcoma in the premaxillary region. This study confirms the favorable results presented in other studies on Brånemark implants to support single-tooth restorations.

The less favorable long-term survival of implants in the orbital rim, especially at irradiated sites, requires further study. 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. 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 (94) A total of 35 patients were treated with VRFPDs, including 17 cases in the maxilla and 18 in the mandible. ICP Biennial Meeting. Failures of the fixed prosthetic restorations were defined as irreversible complications (finish line involved or loss of CCs, FDPs, or abutments). 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 main causes for removal included caries, periodontitis, root fracture, and endodontic complications. 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. The editorial board is composed of a distinguished team of leading international scholars. One cantilevered pontic needed adjustment on the incisal edge due to premature contacts after the 3-year recall examination. 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. 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. The International journal of prosthodontics.. [International College of Prosthodontists. Welcome to THE INTERNATIONAL JOURNAL OF PROSTHODONTICS's online manuscript submission and peer-review system Thank you for submitting to IJP! In general, the soft tissue conditions around the restorations were healthy and comparable to those of the patients' natural teeth. All resin composite eluates, except that for Targis, caused a pronounced cytotoxicity during the first 72 hours that gradually decreased after 2 weeks of aging. The use of one cantilever extension unit had not negatively influenced the results for the fixed partial dentures. Southeastern Academy of Prosthodontics, The Swiss Society of Reconstructive Dentistry Turkish Prosthodontics and Implantology Association, The (Istanbul) (no website) International Journal of Prosthodontics is a Subscription-based (non-OA) Journal. Implant treatment was more predictable before loading in the late group of patients, related to the change in the implant surface (P < .05). 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) 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. Whereas the majority of implanted patients was edentulous in 1990* (64%), the majority in 1995 was partially edentulous (60%). All-ceramic restorations offer a predictable and successful restoration with an estimated survival probability of 93.5% over 10 years. The patients' complaints with the restorations included taste disorders, odynophagia, pain sensations, and functional and esthetic dissatisfaction. Application times of longer than 5 seconds showed obstruction of dentinal tubule openings, possibly a result of abrasive powder residue. 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. Anyone who wants to use the articles in any way must obtain permission from the publishers. Finally, acrylic resin tooth veneers were attached on the buccal surface of posterior maxillary teeth to improve the arch discrepancy. ...

Receiver operating characteristic analysis for all study groups revealed that for age, no clear cutoff point exists with acceptable specificity and sensitivity. Over the last decade, oral implantology has become a major treatment modality to aid the restoration of reduced dentitions. The life table analysis demonstrated a cumulative 6-year survival rate of 92% for auricular implants and 87% for piriform/nasal implants. Title Abbreviation: Int J Prosthodont Title(s): The International journal of prosthodontics. The most common clinical findings were gingival bleeding on probing and appearance of supragingival crown margins. The editorial board is composed of a distinguished team of leading international scholars. The purpose of this study was to investigate the distribution of shades selected for metal ceramic crowns provided at a dental teaching hospital. The type of amalgam and the brand of aluminum oxide affected the bond strength of the resin to amalgam alloy. Further, the definition of poor bone quality has changed. Group 2 patients scored comparably or higher than the normal ridge group (group 3). 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. The incorporation of virtual engineering into dentistry and the digitization of information are providing new perspectives and innovative alternatives for dental treatment modalities. Cytotoxicity is gradually decreased as the composite resins age in a biologic-relevant medium. This study evaluated the marginal fit of experimental and custom-made fixed prosthetic restorations through a new 360-degree external examination. Prosthetic work should be preceded by periodontal examination and prophylactic and periodontal treatment if needed. Biologic and technical complications as well as patient satisfaction were recorded.

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). The success rate was determined using Kaplan-Meier survival analysis. Mats Kronstrom DDS, Odont Dr, PhD; Gunnar E. Carlsson LDS, Odont Dr, PhD; Pages: e622-e626; First Published: 17 March 2017 First, the fossa of mandibular posterior teeth was positioned on the crest of the mandibular edentulous ridge. In the edentulous group, the majority of superstructures in 1990 was fixed prostheses (64%), whereas in 1995 the majority was overdentures (71%). 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. The observation period ranged from 1 to 9 years. The minimum number of measurements required to produce a sample mean value within +/- 5 microm of the mean, calculated over 360 measurements, taking standard error of the means < or = 4 microm, was 18 for experimental and 90 for custom-made crowns, for both equidistant measurement spacing and randomly selected points. Results: Nine FPDs were lost because of extraction of an abutment tooth, and 1 FPD was removed for esthetic reasons. Page 9-13, doi:10.11607/ijp.5822, PubMed:30677106 Assessment of Hypodontia Treatment of Maxillary Lateral Incisors in Adult Patients After 9 Years of Follow-up: A Retrospective Study Those statements are on file at the editorial office. The 5-year overall implant cumulative survival rates were 93.4% and 97.3% for the early and late groups, respectively. The International Journal of Prosthodontics. Ceramics in Prosthodontics.

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. Altogether, 37 patients (20%) were lost to follow-up over 5 years; more patients were noncompliant in the late group (P < .05). Anyone who wants to read the articles should pay by individual or institution to access the articles. 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 study population was a mixture of periodontally affected and non-periodontally affected patients, which is comparable to the population group in a private practice. Twenty-eight total implants (diameter: 3.8 to 5.0 mm) were placed. Read more. The mean follow-up was 15.9 +/- 2.94 months. The International Journal of Prosthodontics is dedicated to exploring and developing this … This study is the first to use oral stereognosis tests for patients with psychologically diagnosed psychogenic dental prosthesis incompatibility. Evidence-based dentistry 2006: Where are we? Tumedei, Margherita et al. Longer observation periods are necessary before this type of restorative design can be recommended as a general conservative procedure. 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. During the 18 years, 41 (30%) failed. Int J Prosthodont 30 (1), 83 … Results: The ability to displace gingiva was indirectly measured by the quality of the final impression. Odds ratios were 1.00 for both PI and BOP. The 5-year prosthesis cumulative survival rate was 97.1% in the early group and 100.0% in the late group. Patients were offered a supportive maintenance program. Two types of implants were used (141 titanium plasma-sprayed and 124 Sand-blasted, large-grit, acid-etched). Data of interest were retrieved retrospectively, compared, and statistically analyzed using Chi-squared tests. A total of 26 implants were placed. One hundred thirty-seven cantilevered fixed partial dentures made between 1974 and 1990 were clinically and radiographically evaluated. International journal of prosthodontics (DLC) 2008213491 (OCoLC)46458410 Online version: International journal of prosthodontics (OCoLC)767573081: Material Type: Periodical, Internet resource: Document Type: Journal / Magazine / Newspaper, Internet Resource: All Authors / Contributors: International College of Prosthodontists. In contrast to other reports in the literature, retentive abutment preparation did not result in a higher survival rate than unprepared abutments. 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. Cementation using Variolink showed significantly fewer failures than Optec Cement (P = .0217) and Dual Cement (P = .0099). Dresden, 23-26 May 2002.

Mucosal hyperplasia and inflammation showed a trend of higher frequency at implants in the early group of patients (P > .05). Mean marginal bone loss and gingival crevice probing depth associated with either implant length were statistically comparable (P> .05). The California Dental Association quality evaluation system was used for assessment of marginal integrity and esthetics. However, prescribing such an examination in patients seeking replacement dentures requires a thorough patient history and clinical examination. 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). 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. The crowns were placed between 1989 and 1995. Genre/Form: Periodicals: Additional Physical Format: International journal of prosthodontics (DLC)sn 87000947 (OCoLC)15434404: Material Type: Document, Periodical, Internet resource Other Titles: Purpose: To establish a complete digital workflow for the design and manufacture of sports mouthguards and to observe preliminary clinical effects. It is possible to achieve high survival rates of implants in the auricular and piriform/nasal sites through careful presurgical and radiographic planning. Successful sinus membrane water balloon lifting procedures were performed in 26 cases; two procedures were aborted due to sinus membrane perforation. 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. Significantly increased failure rates are associated with bruxism, nonvital teeth, and specific cementation agents. The latest h-index of International Journal of Prosthodontics is 88.The h-index is defined as the maximum value of h such that the given author/journal has published h papers that have each been cited at least h times. 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 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 majority (85%) of the fixed partial dentures were acrylic resin veneer-gold restorations; 15% were metal ceramic restorations. The patient has kept up with his oral hygiene, using conventional methods for the teeth and prosthesis, with periodic flushing with chlorhexidine solution. It was concluded that airborne particle abrasion removes the smear layer, and the amount of dentin removed corresponded to the time of application. 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). 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). 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. 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. He has lived a normal family life and finished his university education. However, when there were deep subgingival margins and a beveled preparation, the material was less effective than the single cord retraction technique. The long-term results were good, especially for the metal ceramic restorations: 79% remained unchanged and only 3% had been removed. For further information, please contact Rachel Yehl at ryehl@prosthodontics.org. 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. Conclusion: The results were similar to those for complete and partial osseointegrated prostheses. The patients in the test group expressed clear dissatisfaction with their dentures. A surgical guide was obtained by a 3D printer, and the surgical procedure was done using the Biohorizons Guided Surgery Kit and its protocol. The main reason for failure was fracture of the ceramic (33.68%). Int J Prosthodont 2010;23:243-245. 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. In the remaining 106 patients (223 implants), 8 implants failed (4 standard and 4 shorter), in type 3 or 4 bone. 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. No significant differences were found for type of restoration and distribution in the mouth. The aim of this study was to quantify the frequency of positive radiographic findings in edentulous arches. Author(s): International College of Prosthodontists. Furthermore we use Google Analytics to create anonymized statistical reports of the usage which creates Cookies too. Baseline bone height was 4.92 +/- 1.24 mm. Technical problems recorded included loss of cementation, fractures in the metal framework, and need for placement of a dowel in an abutment tooth. The remaining 2 lost implants were managed by converting the distal unit of the fixed partial prosthesis to a cantilever. 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). An International Survey among Prosthodontists of the Use of Mandibular Implant‐Supported Dental Prostheses. 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. Control specimens were unreinforced. Carious lesions were found on 4% of the abutment teeth. Latest issue: Issue 6/2020. 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. A total of 28 patients with a single tooth missing in the posterior maxilla underwent a water balloon sinus lift, followed by bone grafting and implant placement. Purpose: 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). Endodontic treatment was performed for a low number (2%) of the AllCeram crowns. 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. 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. The results have direct implications on socioeconomic and forensic consequences for diagnosis and treatment by a dental clinician. With respect to the type of superstructures, there was a strong increase in the number of single-tooth replacements (from 4% to 23%). The monthly publication features timely, original peer-reviewed articles on the newest techniques, dental materials, and research findings. The study population included 106 (35.1%) individuals diagnosed with bruxism. The tensile bond strengths of a resin cement, Panavia Ex, to a spherical and an admixed amalgam were measured after surface treatment with different aluminum oxide abrasive spray procedures. 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 resistance against dislodgment of the denture was low in all three groups. All patients who received oral implants in 1990* and in 1995 were selected, and their files (95 and 105, respectively) were consulted. The aim of this study was to determine the effect of long-term water immersion on the flexural properties of fiber-reinforced composite. 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. A removable partial denture was retained by the attachments and conventional cast retentive circumferential clasps, including a hollow obturator filling the defect. A total of 9 patients (10 implants) was lost to follow-up. These results underscore the importance of panoramic examination of edentulous patients in detecting potential problems before complete denture treatment. During the study period, 35 implants failed to integrate, and the survival rate for all exposed implants was 80%. During a mean observation time of 46.57 months, 35 VRFPDs on vital abutment teeth did not exhibit postoperative sensitivity or secondary caries. Two crowns, chosen from among the 14 previously evaluated, were reanalyzed to determine the minimum number of gap measurements required to produce significant results for gap analysis. This study investigated the effect of airborne particle abrasion on the exposed dentin surfaces of 40 extracted teeth. 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. By 1995 there was a threefold increase in both the number of patients and the number of implants placed per year. The editors of the Journal of Prosthodontics are pleased to present this virtual issue on the latest technological advances in ceramics. 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).

One implant was lost due to infection. They were placed on your computer when you launched this website. Although carefully collected, accuracy cannot be guaranteed. This paper reports the clinical experience of 47 patients treated for a single-tooth replacement. The editorial board is composed of a distinguished team of leading international scholars. 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 study cohort comprised 83 patients with complete dentures fabricated according to a standardized protocol. International Journal of Periodontics & Restorative Dentistry. The precision obtained with the custom-made crowns differed from that of the experimental specimens. Periodontal variables were measured, including Plaque Index (PI), bleeding on probing (BOP), probing pocket depth (PPD), and attachment level. 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. Get this from a library! 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. Purpose: The differences between the three groups were evaluated 6.5 years after treatment. 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. The selection of more than one shade for a crown ("mixed shades") was generally restricted to the maxillary anterior teeth. The estimated survival rate was 97.3% after 5 years, 93.5% at 10 years, and 78.5% at 20 years. The results were compared with an established retraction system using one retraction cord. Multiunit resin-bonded fixed partial dentures had a smaller probability of survival than three-unit resin-bonded fixed partial dentures. This method has encouraging results, is easy to learn, and is associated with low complication rates. More mandibular restorations failed than did maxillary units, but the difference was not significant. There was a clear statistically significant association between age and irreversible complications. Six crowns (7%) were recorded as failures; five of these crowns (6%) had to be remade. This study aimed to examine the influence of osseointegrated implants on decision making for prosthodontic treatments. The clinical performance of 325 resin-bonded fixed partial dentures (RBFPD) placed between 1984 and 1995 was reviewed. Two hundred sixty-nine abutment teeth were evaluated. In all FRC-FPD models, the FRC framework showed stress-bearing capacity for the FPD. Also, in 1995 more maxillae were implanted than in 1990* (44% vs 26%). The total implant survival rate was 94.4%. Each framework was compared with a hybrid composite FPD without any fiber reinforcement (C-FPD). 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). To read the Full Author Guidelines, click here.. There was a 2.3-times greater risk of failure associated with existing parafunction (bruxism, P = .0045). Esthetic match, porcelain surface, marginal discoloration, and integrity were evaluated following modified California Dental Association/Ryge criteria. 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. Endodontic complications on abutment teeth were more frequent in the mandible than in the maxillae. Nonvital teeth showed a significantly higher risk of failure (P < .0001). Cantilevered IPS e.max Press VRFPDs should be considered a minimally invasive, single-tooth restorative strategy in the anterior or first premolar area. 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). Data provided are for informational purposes only. Sixty-seven screw-type standard, self-tapping implants and mini-implants were placed. Latest issue: Issue 5/2020. The information was imported to and combined in the 3Shape Implant Studio software for guided implant surgery planning. Of the prosthetic restorations, 165 were all-ceramic (68%), 79 were metal-ceramic (31%), and 4 were gold-acrylic (1%). This study investigated the survival of complete crowns in relation to periodontal variables on a long-term basis. Ultimate transverse strength and flexural modulus of unreinforced and fiber-reinforced composite test specimens decreased during water storage (P < 0.001, analysis of variance). Scanning electron micrographs showed smear layer removal as an immediate effect of air polishing. 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). Dropouts were recorded for 23 patients with 23 prostheses supported by 42 implants. 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. 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. Using plaster models 4 times the normal tooth size showed that the accuracy of the reconstructed model was estimated at roughly 30 microm, which potentially could be used in direct intraoral applications. Results: Implant treatment has been performed for more than 45 years, but there is still limited knowledge on how treatment outcomes are changing over time. Fibers were oriented at a 45-degree angle to the long axis of the test specimens. 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. The higher failure rate was related not only to periodontal disease, but also to a wide range of biologic and technical problems. 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. 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. A number of statistically significant differences was apparent between these 2 periods. 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. The bone loss was of the same magnitude as in other studies on Brånemark implants as support for single crowns. Ninety-five failures were recorded. Implant site preparation employed a pilot drill and osteotomy followed by water balloon elevation. Postoperative patient reactions including swelling, discoloration, discomfort, hematomas, and disability were recorded. The highest stress reduction ratio under all loading conditions was obtained using the FRC1 model. No patient complained of food impaction. The restoration has served the patient for 16 years, seemingly without discomfort, and it has not required any maintenance. MMT decreased by 17% during denture abstention following repeated implant surgery, and returned to 100% during the 12 months with the mandibular IOD. One major use of ISO 4 is to abbreviate the names of scientific journals. This report explains how relatively uncomplicated prosthodontic measures can enormously affect quality of life.

Page 487-492, doi:10.11607/ijp.6470, PubMed:32956429 Perceptibility and Acceptability of Color Differences of Single-Tooth Implants at the Restoration … 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. The reproduction of the preparation finish line and an absence of bubbles or voids (Criteria I through III) were assesed. The most frequent finding (30.6%) was close approximation of the maxillary sinus to the crest of the ridge. Thus, psychogenic prosthesis incompatibility can be classified more explicitly as a psychosomatic disorder. 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 degree of satisfaction was indicated with a visual analog scale. The association between gender versus irreversible complications for the CCs (P = .481), 3uFDPs (P= .814), and FDPs (P = .410) groups was not statistically significant. 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. A dental history questionnaire was used to evaluate whether the patients had adapted to their dentures 6 months after incorporation. Provides the worldwide dental community with current, scientifically sound information on patient care, research, and education in prosthodontics and interrelated disciplines. This could possibly be attributed to a more bioactive implant surface and shorter healing period before implant surgery in the late group. 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. A total of 1,037 complete crowns made in an undergraduate clinic for 456 patients were evaluated over an 18-year period. 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.

The results of this study suggest that the ultimate transverse strength of the fiber-reinforced composite made from E-glass fibers is reduced by approximately 27% compared to the dry fiber-reinforced composite. 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. The survival rate of the FPDs was 78%, and the established success rate was 71%. Clinical examination was performed during patients' regularly scheduled maintenance appointments. 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. Base metal alloys, silicoating, mesh retention, and immobile abutments were positive factors. Nearly twice as many impressions were rated Criteria III when using the Magic FoamCord (MFC) system compared to impressions done with the single cord retraction technique. Six of the 8 lost implants required implant replacement after the host sites' healing period. 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). The stability of the mandibular dentures as well as the retention were better in group 2 than were those in group 1. EndNote Styles - International Journal of Prosthodontics. A 55-year-old Japanese woman received periodontal therapy and cross-arch fixed partial dentures were placed in the maxilla and mandible. Bio-Oss was filled under the elevated sinus membrane using a dedicated instrument. 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. Of these, 35 (25%) were removed after a mean of 11 years in function, which left 75% in place and functioning after 18 years. The primary indications of the 264 patients treated were trauma and aplasia. There was no relationship between gender and irreversible complications. Continuous, woven, silanized E-glass fibers and woven silica fibers were used to reinforce heat-cured and autopolymerized denture base polymers. This study presents a method of using shadow-speckle correlation to reconstruct a 3-dimensional (3D) tooth model. The mean observation time was 102 ± 60 months. Bleeding was somewhat more often recorded at teeth with AllCeram crowns (39%) than at contralateral teeth (27%). 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. Of those that "failed," 28 (68%) were in the maxillae and 13 (32%) were in the mandible. 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).

Int J Prosthodont 2011;24:356-362. Patients receiving artificial crowns and fixed partial dentures at a prosthodontic clinic were examined 18 to 23 years after treatment. Small restorations in the bonding area did not affect the survival. Including the rebonded restorations, the survival rate calculated using the Kaplan-Meier method was 76% after 5 years and 60% after 10 years. Generally, those abutment teeth that had been removed during the observation period had received previous endodontic treatment before restorations had been placed. 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. 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. The estimated survival rate was 78% at year 18. In relation to complete crown survival, caution is needed in patients with a high CPITN at baseline. On the other hand, it was observed that the prevalence of patients with more bone loss at at least 1 implant (> 2 mm) was higher in the late group (P < .05). 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). Materials and methods: One or more of these radiographic observations were found in 51.7% of the examined films. 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. Furthermore, shades in the reddish-grey range of hue were rarely chosen. The outcome is also in agreement with that reported for metal-ceramic crowns. 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. 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. Conclusion: Prosthetic treatment and maintenance of implant-supported fixed prostheses improved significantly between the groups. These findings indicate that resin-based dental restorative materials release agents cytotoxic and genotoxic to fibroblasts. The problem-free use of the appliance can be at least partly explained by the patient taking oral hygiene measures seriously from the beginning. Int J Prosthodont 2011;24:314-319. 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. The results indicate a good prognosis for Procera AllCeram crowns also for posterior teeth. 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. This method addresses functional considerations with the inner aspect of teeth and esthetic considerations with acrylic resin tooth veneers. Official Journal of the International College of Prosthodontists and the International Society for Maxillofacial Rehabilitation. Osseointegration has influenced the decision-making process in prosthodontic treatments related to extraction. Conclusion: 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. In contrast, the survival rate for orbital implants showed a steady downward trend and reached 59% at 66 months. Statistical analysis (Spearman Rank Order) showed a significant difference between all groups (P < .05) but not within groups (P > .05). 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. 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 prosthesis length ratio and the crown length-bone ratio did not influence the failure rate. 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). Computed tomography showed the bone graft distributing evenly around implants. The removal rate for abutments with cast posts and cores was higher than the removal rate of total abutments. Significantly lower bond strengths were obtained between Panavia and the admixed amalgam alloy. Preliminary Clinical Application of Complete Workflow of Digitally Designed and Manufactured Sports Mouthguards. You will find more information in our, The International Journal of Prosthodontics. DNA gel electrophoresis was performed to detect possible genotoxicity and DNA damage. Morphologic changes attributable to cytotoxicity were observed by May-Grunwald-Giemsa cytologic staining and microscopic examination. Both groups were followed and evaluated clinically and radiographically for 5 years according to similar protocols. Furthermore we use Google Analytics to create anonymized statistical reports of the usage which creates Cookies too. Int J Prosthodont 2011;24:345-355. 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. Median duration was 84 +/- 3.6 months. After 18 years, STE developed in the left posterior region of the mandible. The mean follow-up period was 17.7 years (range: 17.1 to 21.3 years). The patient group of < or = 40 years of age had significantly increased, from 7% to 23%. 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. There was no difference in removal frequency between fixed partial dentures with moderate cantilever extensions and those with end-supported extensions. During this study period, 14 individuals died, leaving 138 fixed partial dentures to be examined. Twelve patients diagnosed with psychogenic prosthesis incompatibility (11 women, 1 man) using the SCL-90-R and CES-D scales in a previous study and a group of 24 randomly selected control subjects (14 women, 10 men) underwent an oral stereognosis test with 10 neutral-tasting plastic test specimens with a maximum edge length of 8 mm in 2 test cycles. Failures occurred significantly more when endodontically treated abutments were used. Implant Treatment with Fixed Prostheses in the Edentulous Maxilla. The 14-year cumulative survival rates for all short and standard implants were 97.9% and 97.1%, respectively. 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.
