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. 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. Only 6.3% of the impressions were unacceptable and categorized as Criteria III.

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). A total of 1,037 complete crowns made in an undergraduate clinic for 456 patients were evaluated over an 18-year period. The incorporation of virtual engineering into dentistry and the digitization of information are providing new perspectives and innovative alternatives for dental treatment modalities. 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. In all FRC-FPD models, the FRC framework showed stress-bearing capacity for the FPD. Sixty-seven screw-type standard, self-tapping implants and mini-implants were placed. 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. 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. Six of the 8 lost implants required implant replacement after the host sites' healing period. This study investigated the effect of airborne particle abrasion on the exposed dentin surfaces of 40 extracted teeth. No correlation was found between oral stereognostic ability and the SCL-90-R or CES-D values. Clinical examination was performed during patients' regularly scheduled maintenance appointments. Major changes in oral implantology treatments were noticed between the 1990* and 1995 periods at ACTA. 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.

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. Latest issue: Issue 5/2020. One implant was lost due to infection. Further, the definition of poor bone quality has changed. 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. Mucosal hyperplasia and inflammation showed a trend of higher frequency at implants in the early group of patients (P > .05). The patients found the esthetics to be excellent. The crowns were placed between 1989 and 1995. The resistance against dislodgment of the denture was low in all three groups. The information was imported to and combined in the 3Shape Implant Studio software for guided implant surgery planning. One or more of these radiographic observations were found in 51.7% of the examined films. Furthermore, shades in the reddish-grey range of hue were rarely chosen. 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. Adaptation problems were ruled out as a possible cause. Of those that "failed," 28 (68%) were in the maxillae and 13 (32%) were in the mandible. The use of a water balloon to elevate the sinus membrane is a truly minimally invasive technique and is associated with very little discomfort. They were placed on your computer when you launched this website. 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). Implant Treatment with Fixed Prostheses in the Edentulous Maxilla. 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. ICP Newsletter - September 2020. Bleeding was somewhat more often recorded at teeth with AllCeram crowns (39%) than at contralateral teeth (27%). A total of 9 patients (10 implants) was lost to follow-up. Auricular implants showed the highest survival rate (95%), and orbital implants showed the lowest survival rate (53%). Significantly lower bond strengths were obtained between Panavia and the admixed amalgam alloy. MMT decreased by 17% during denture abstention following repeated implant surgery, and returned to 100% during the 12 months with the mandibular IOD. Publishers own the rights to the articles in their journals. 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 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. Author(s): International College of Prosthodontists. However, prescribing such an examination in patients seeking replacement dentures requires a thorough patient history and clinical examination. More mandibular restorations failed than did maxillary units, but the difference was not significant. 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. The type of amalgam and the brand of aluminum oxide affected the bond strength of the resin to amalgam alloy. Journal of Prosthodontic Research originated as an official journal of Japan Prosthodontic Society. This could possibly be attributed to a more bioactive implant surface and shorter healing period before implant surgery in the late group. Osseointegration has influenced the decision-making process in prosthodontic treatments related to extraction. Small restorations in the bonding area did not affect the survival. A 55-year-old Japanese woman received periodontal therapy and cross-arch fixed partial dentures were placed in the maxilla and mandible. 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. A total of 207 implants were placed in 72 patients, and 182 implants had been uncovered. Six crowns (7%) were recorded as failures; five of these crowns (6%) had to be remade. Carious lesions were found on 4% of the abutment teeth. Biomechanical stress and microgap analysis of bone-level and tissue-level implant abutment structure according to the five different directions of occlusal loads 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. Cantilevered IPS e.max Press VRFPDs should be considered a minimally invasive, single-tooth restorative strategy in the anterior or first premolar area. 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. One cantilevered pontic needed adjustment on the incisal edge due to premature contacts after the 3-year recall examination. Purpose: The remaining 2 lost implants were managed by converting the distal unit of the fixed partial prosthesis to a cantilever. 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. Purpose: To establish a complete digital workflow for the design and manufacture of sports mouthguards and to observe preliminary clinical effects. Cytotoxicity was determined by counting the number of viable cells by trypan blue exclusion. The present report describes a relatively simple but effective prosthodontic treatment following removal of a moderately well differentiated osteogenic chondrosarcoma in the premaxillary region. 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). 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. 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. A total of 35 patients were treated with VRFPDs, including 17 cases in the maxilla and 18 in the mandible. The clinical performance of 325 resin-bonded fixed partial dentures (RBFPD) placed between 1984 and 1995 was reviewed. The editorial board is composed of a distinguished team of leading international scholars. A surgical guide was obtained by a 3D printer, and the surgical procedure was done using the Biohorizons Guided Surgery Kit and its protocol. Furthermore we use Google Analytics to create anonymized statistical reports of the usage which creates Cookies too. 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 total implant survival rate was 94.4%. The results have direct implications on socioeconomic and forensic consequences for diagnosis and treatment by a dental clinician. The 5-year overall implant cumulative survival rates were 93.4% and 97.3% for the early and late groups, respectively. 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). 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. The restoration has served the patient for 16 years, seemingly without discomfort, and it has not required any maintenance. Severe morphologic alterations and pronounced DNA damage were also observed. Base metal alloys, silicoating, mesh retention, and immobile abutments were positive factors. Data were obtained from patient charts. The minimum number of gap measurements required to produce relevant results for gap analysis was also investigated. 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. Int J Prosthodont 2011;24:314-319. The most common clinical findings were gingival bleeding on probing and appearance of supragingival crown margins.

Cementation using Variolink showed significantly fewer failures than Optec Cement (P = .0217) and Dual Cement (P = .0099). Int J Prosthodont 2011;24:345-355. The observation period ranged from 1 to 9 years. This study obtained information on the long-term efficiency of prosthetic rehabilitation with fixed partial dentures performed by undergraduate students. Int J Prosthodont 2010;23:243-245. This method addresses functional considerations with the inner aspect of teeth and esthetic considerations with acrylic resin tooth veneers. The aim of this study was to determine the effect of long-term water immersion on the flexural properties of fiber-reinforced composite. The California Dental Association quality evaluation system was used for assessment of marginal integrity and esthetics. A number of statistically significant differences was apparent between these 2 periods. 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. Caries was the most frequent reason for failure, followed by periodontal disease. Of the prosthetic restorations, 165 were all-ceramic (68%), 79 were metal-ceramic (31%), and 4 were gold-acrylic (1%). Control specimens were unreinforced. 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). He has lived a normal family life and finished his university education. Continuous, woven, silanized E-glass fibers and woven silica fibers were used to reinforce heat-cured and autopolymerized denture base polymers. Ninety-five failures were recorded. The degree of satisfaction was indicated with a visual analog scale. Journey's End: Dr John W. McLean 1925-2009. For the CPITN, odds ratios were 3.00 to 3.83. 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. 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." Patients were offered a supportive maintenance program. In cases of epigingival and subgingival (< 2 mm) preparation margins, MFC was a less traumatic alternative method of gingival retraction. 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. 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 results indicate that the most frequently chosen shades were in the mid-range of reddish-brown hue. 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. Results: The maxillary posterior teeth were then placed palatally to maximize occlusal contacts with the opposing mandibular teeth. This method has encouraging results, is easy to learn, and is associated with low complication rates. Nonvital teeth showed a significantly higher risk of failure (P < .0001). 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. Each framework was compared with a hybrid composite FPD without any fiber reinforcement (C-FPD). 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. 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. 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). The reproduction of the preparation finish line and an absence of bubbles or voids (Criteria I through III) were assesed. 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.

Page 487-492, doi:10.11607/ijp.6470, PubMed:32956429 Perceptibility and Acceptability of Color Differences of Single-Tooth Implants at the Restoration … Bio-Oss was filled under the elevated sinus membrane using a dedicated instrument. This study evaluated the marginal fit of experimental and custom-made fixed prosthetic restorations through a new 360-degree external examination. The mean observation time was 102 ± 60 months. 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. Results: Nine FPDs were lost because of extraction of an abutment tooth, and 1 FPD was removed for esthetic reasons. The study cohort comprised 83 patients with complete dentures fabricated according to a standardized protocol. Official Journal of the International College of Prosthodontists and the International Society for Maxillofacial Rehabilitation. 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. 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. 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. Thus, psychogenic prosthesis incompatibility can be classified more explicitly as a psychosomatic disorder. 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. Periodontal variables were measured, including Plaque Index (PI), bleeding on probing (BOP), probing pocket depth (PPD), and attachment level. Those statements are on file at the editorial office. Of these, 35 (25%) were removed after a mean of 11 years in function, which left 75% in place and functioning after 18 years. 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. Differences in fit between experimental specimens and custom-made ones showed that experimental results might not always be obtained in clinical practice. 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). First, the fossa of mandibular posterior teeth was positioned on the crest of the mandibular edentulous ridge. Title Abbreviation: Int J Prosthodont Title(s): The International journal of prosthodontics. For further information, please contact Rachel Yehl at ryehl@prosthodontics.org. Conclusion: The study cohort comprised 83 patients with complete dentures fabricated according to a standardized protocol. Welcome to THE INTERNATIONAL JOURNAL OF PROSTHODONTICS's online manuscript submission and peer-review system Thank you for submitting to IJP! ACP members must be logged in to access the Journal.. Altogether, 37 patients (20%) were lost to follow-up over 5 years; more patients were noncompliant in the late group (P < .05). 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. 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). 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. Endodontic treatment was performed for a low number (2%) of the AllCeram crowns. 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. Int J Prosthodont 30 (1), 83 … The International journal of prosthodontics.. [International College of Prosthodontists. Although carefully collected, accuracy cannot be guaranteed. Dropouts were recorded for 23 patients with 23 prostheses supported by 42 implants. (Dorothy Kidd 2002). The editors of the Journal of Prosthodontics are pleased to present this virtual issue on the latest technological advances in ceramics. 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. Dresden, 23-26 May 2002. 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. 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 higher failure rate was related not only to periodontal disease, but also to a wide range of biologic and technical problems. Implant site preparation employed a pilot drill and osteotomy followed by water balloon elevation. Tumedei, Margherita et al. 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. SCOPE. 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. Twenty-eight total implants (diameter: 3.8 to 5.0 mm) were placed. This study confirms the favorable results presented in other studies on Brånemark implants to support single-tooth restorations. In the edentulous group, the majority of superstructures in 1990 was fixed prostheses (64%), whereas in 1995 the majority was overdentures (71%). 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. This study aimed to investigate the occurrence of subpontic tissue enlargement (STE) beneath a mandibular fixed partial denture. Int J Prosthodont 2011;24:356-362. The differences between the three groups were evaluated 6.5 years after treatment. The aim of the study was to evaluate AllCeram crowns in dental practice over a 5- to 10.5-year period. INTERNATIONAL. The outcome is also in agreement with that reported for metal-ceramic crowns. Number of restoration failures and reasons for failure were recorded. Over the last decade, oral implantology has become a major treatment modality to aid the restoration of reduced dentitions. The precision obtained with the custom-made crowns differed from that of the experimental specimens. Conclusion: Prosthetic treatment and maintenance of implant-supported fixed prostheses improved significantly between the groups. Mean marginal bone loss and gingival crevice probing depth associated with either implant length were statistically comparable (P> .05). There was a 2.3-times greater risk of failure associated with existing parafunction (bruxism, P = .0045). In contrast to other reports in the literature, retentive abutment preparation did not result in a higher survival rate than unprepared abutments. The removal rate for abutments with cast posts and cores was higher than the removal rate of total abutments. The 5-year prosthesis cumulative survival rate was 97.1% in the early group and 100.0% in the late group.

Other Titles: Both groups were followed and evaluated clinically and radiographically for 5 years according to similar protocols. The use of one cantilever extension unit had not negatively influenced the results for the fixed partial dentures. 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). Prosthetic work should be preceded by periodontal examination and prophylactic and periodontal treatment if needed. All-ceramic restorations offer a predictable and successful restoration with an estimated survival probability of 93.5% over 10 years. Some of the AllCeram crowns were among the very first that were placed. 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. The stability of the mandibular dentures as well as the retention were better in group 2 than were those in group 1. 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. Valente, Nicola Alberto et al. Morphologic changes attributable to cytotoxicity were observed by May-Grunwald-Giemsa cytologic staining and microscopic examination. A total of 8 crowns was remade following prosthetic complications; otherwise, the frequency of adverse events was low. The aim of this study was to quantify the frequency of positive radiographic findings in edentulous arches. The International Journal of Prosthodontics is dedicated to exploring and developing this … During the study period, 35 implants failed to integrate, and the survival rate for all exposed implants was 80%. Preliminary Clinical Application of Complete Workflow of Digitally Designed and Manufactured Sports Mouthguards. During the 18 years, 41 (30%) failed. The FRC1 framework also best reduced displacement of the framework. Implant treatment has been performed for more than 45 years, but there is still limited knowledge on how treatment outcomes are changing over time. This paper reports the clinical experience of 47 patients treated for a single-tooth replacement. Esthetic match, porcelain surface, marginal discoloration, and integrity were evaluated following modified California Dental Association/Ryge criteria. No significant differences were found for type of restoration and distribution in the mouth. Data provided are for informational purposes only. The overall success rate of cantilever fixed prostheses was 70% over a period of 18 years. Whereas the majority of implanted patients was edentulous in 1990* (64%), the majority in 1995 was partially edentulous (60%). Twelve clinicians at nine clinics placed 87 crowns in 50 patients. 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. 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. 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. Technical problems recorded included loss of cementation, fractures in the metal framework, and need for placement of a dowel in an abutment tooth. An International Survey among Prosthodontists of the Use of Mandibular Implant‐Supported Dental Prostheses. DNA gel electrophoresis was performed to detect possible genotoxicity and DNA damage. Longer observation periods are necessary before this type of restorative design can be recommended as a general conservative procedure. The purpose of this study was to investigate the distribution of shades selected for metal ceramic crowns provided at a dental teaching hospital. Multiunit resin-bonded fixed partial dentures had a smaller probability of survival than three-unit resin-bonded fixed partial dentures. In relation to complete crown survival, caution is needed in patients with a high CPITN at baseline. Only those crowns placed adjacent to minimally restored vital teeth were included in the study. The editorial board is composed of a distinguished team of leading international scholars. The success rate for the gold-resin restorations was less favorable: 43% remained unchanged and 33% had been removed. EndNote Styles - International Journal of Prosthodontics. The life table analysis demonstrated a cumulative 6-year survival rate of 92% for auricular implants and 87% for piriform/nasal implants. 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. 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. The main reason for failure was fracture of the ceramic (33.68%). 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.

These findings indicate that resin-based dental restorative materials release agents cytotoxic and genotoxic to fibroblasts. 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. 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. Ceramics in Prosthodontics. ICP Biennial Meeting. Including the rebonded restorations, the survival rate calculated using the Kaplan-Meier method was 76% after 5 years and 60% after 10 years. Statistical analysis (Spearman Rank Order) showed a significant difference between all groups (P < .05) but not within groups (P > .05). This study is the first to use oral stereognosis tests for patients with psychologically diagnosed psychogenic dental prosthesis incompatibility. 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. 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. A dental history questionnaire was used to evaluate whether the patients had adapted to their dentures 6 months after incorporation. The results indicate a good prognosis for Procera AllCeram crowns also for posterior teeth. This case suggests that muscle bulk may be related to denture function.

Purpose: ICP journal. 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. EndNote Styles - International Journal of Prosthodontics. 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. However, when there were deep subgingival margins and a beveled preparation, the material was less effective than the single cord retraction technique. 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. This study presents a method of using shadow-speckle correlation to reconstruct a 3-dimensional (3D) tooth model. Ultimate transverse strength and flexural modulus of unreinforced and fiber-reinforced composite test specimens decreased during water storage (P < 0.001, analysis of variance). Int J Prosthodont 33 (2020), No. No fractures or chipping of the restorations occurred within the course of the evaluation. 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. 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. Author Guidelines. 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. Group 2 patients scored comparably or higher than the normal ridge group (group 3). The ability to displace gingiva was indirectly measured by the quality of the final impression. The International journal of prosthodontics | Citations: 3,491 | Official Journal of the International College of Prosthodontists and the International Society for Maxillofacial Rehabilitation. The mean follow-up was 15.9 +/- 2.94 months. The highest stress reduction ratio under all loading conditions was obtained using the FRC1 model. The estimated survival rate was 78% at year 18. In contrast, the survival rate for orbital implants showed a steady downward trend and reached 59% at 66 months. The prosthesis length ratio and the crown length-bone ratio did not influence the failure rate. The association between gender versus irreversible complications for the CCs (P = .481), 3uFDPs (P= .814), and FDPs (P = .410) groups was not statistically significant. 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. The marginal integrity was considered excellent or acceptable for 92% of the crowns. These results underscore the importance of panoramic examination of edentulous patients in detecting potential problems before complete denture treatment. The survival rate of the FPDs was 78%, and the established success rate was 71%. Patients were extremely pleased with the results and needed very little medical attention after surgery. Provides the worldwide dental community with current, scientifically sound information on patient care, research, and education in prosthodontics and interrelated disciplines. 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 selection of more than one shade for a crown ("mixed shades") was generally restricted to the maxillary anterior teeth. 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. Dry test specimens and those stored in water for up to 180 weeks were tested with a 3-point loading apparatus. No patient complained of food impaction. This study investigated the survival of complete crowns in relation to periodontal variables on a long-term basis. Biologic and technical complications as well as patient satisfaction 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. 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. There was no relationship between gender and irreversible complications. 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. Genre/Form: Periodicals: Additional Physical Format: International journal of prosthodontics (DLC)sn 87000947 (OCoLC)15434404: Material Type: Document, Periodical, Internet resource The monthly publication features timely, original peer-reviewed articles on the newest techniques, dental materials, and research findings. Materials and methods: All patients who received oral implants in 1990* and in 1995 were selected, and their files (95 and 105, respectively) were consulted. One major use of ISO 4 is to abbreviate the names of scientific journals. The patients' complaints with the restorations included taste disorders, odynophagia, pain sensations, and functional and esthetic dissatisfaction. PI and BOP were not directly related to the frequency of failures. 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). 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. 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. Patients receiving artificial crowns and fixed partial dentures at a prosthodontic clinic were examined 18 to 23 years after treatment. The study population included 106 (35.1%) individuals diagnosed with bruxism. 1 (23.12.2019) Page 99-104, doi:10.11607/ijp.6348, PubMed:31860919 Preliminary Clinical Application of Complete Workflow of Digitally Designed and … 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. Fibers were oriented at a 45-degree angle to the long axis of the test specimens. It is possible to achieve high survival rates of implants in the auricular and piriform/nasal sites through careful presurgical and radiographic planning. In general, the soft tissue conditions around the restorations were healthy and comparable to those of the patients' natural teeth. A total of 163 fixed partial dentures were inserted. A total of 26 implants were placed. The less favorable long-term survival of implants in the orbital rim, especially at irradiated sites, requires further study. 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 patient has kept up with his oral hygiene, using conventional methods for the teeth and prosthesis, with periodic flushing with chlorhexidine solution. It was presumed that biomechanical loading in the mandible, along with other factors, might have caused the STE in this particular patient. 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. The mean follow-up period was 17.7 years (range: 17.1 to 21.3 years). The Community Periodontal Index for Treatment Needs (CPITN) was calculated per sextant in a full-mouth assessment. The editorial board is composed of a distinguished team of leading international scholars. The results were compared with an established retraction system using one retraction cord. materials and methods: A three-unit FPD replacing the maxillary right lateral incisor was constructed using FE analysis software (ANSYS 10.0, ANSYS). 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. After 18 years, STE developed in the left posterior region of the mandible. This report explains how relatively uncomplicated prosthodontic measures can enormously affect quality of life. Get this from a library! During this study period, 14 individuals died, leaving 138 fixed partial dentures to be examined. There was no difference in removal frequency between fixed partial dentures with moderate cantilever extensions and those with end-supported extensions. ... Grant Funding, Networking with Global Prosthodontic Leaders and Advocates of Prosthodontics, Free Webinars and more... We Invite You to Join the ICP! 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. Failures of the fixed prosthetic restorations were defined as irreversible complications (finish line involved or loss of CCs, FDPs, or abutments). The mean inflated balloon volume was 0.67 +/- 0.17 mL. Successful sinus membrane water balloon lifting procedures were performed in 26 cases; two procedures were aborted due to sinus membrane perforation. 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). Implant treatment was more predictable before loading in the late group of patients, related to the change in the implant surface (P < .05). Materials and methods: Two hundred sixty-nine abutment teeth were evaluated. International Journal of Periodontics & Restorative Dentistry. 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. 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. 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). 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. 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. There was a clear statistically significant association between age and irreversible complications. Both groups were followed for 5 years with regard to prosthetic treatment, clinical maintenance, and complications. Data of interest were retrieved retrospectively, compared, and statistically analyzed using Chi-squared tests. The 14-year cumulative survival rates for all short and standard implants were 97.9% and 97.1%, respectively. 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. By 1995 there was a threefold increase in both the number of patients and the number of implants placed per year. Anyone who wants to read the articles should pay by individual or institution to access the articles. 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. Significantly increased failure rates are associated with bruxism, nonvital teeth, and specific cementation agents. 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 patient group of < or = 40 years of age had significantly increased, from 7% to 23%. ;] Postoperative patient reactions including swelling, discoloration, discomfort, hematomas, and disability were recorded. Also, in 1995 more maxillae were implanted than in 1990* (44% vs 26%). 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. 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. Median duration was 84 +/- 3.6 months.

One hundred thirty-seven cantilevered fixed partial dentures made between 1974 and 1990 were clinically and radiographically evaluated. Baseline bone height was 4.92 +/- 1.24 mm. The results suggest that single-tooth replacement using osseointegrated implants provides predictable success. 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). This study aimed to examine the influence of osseointegrated implants on decision making for prosthodontic treatments. The success rate was determined using Kaplan-Meier survival analysis. 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. Get this from a library! The primary indications of the 264 patients treated were trauma and aplasia. 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).
