The higher failure rate was related not only to periodontal disease, but also to a wide range of biologic and technical problems. Anyone who wants to use the articles in any way must obtain permission from the publishers. Data of interest were retrieved retrospectively, compared, and statistically analyzed using Chi-squared tests. Purpose: 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. Computed tomography showed the bone graft distributing evenly around implants. Preliminary Clinical Application of Complete Workflow of Digitally Designed and Manufactured Sports Mouthguards. By 1995 there was a threefold increase in both the number of patients and the number of implants placed per year. Furthermore, shades in the reddish-grey range of hue were rarely chosen. Each framework was compared with a hybrid composite FPD without any fiber reinforcement (C-FPD). The results have direct implications on socioeconomic and forensic consequences for diagnosis and treatment by a dental clinician. The mean follow-up was 15.9 +/- 2.94 months. Catch up on the latest ICP News! Altogether, 37 patients (20%) were lost to follow-up over 5 years; more patients were noncompliant in the late group (P < .05). The International Journal of Prosthodontics' journal/conference profile on Publons, with 77 reviews by 17 reviewers - working with reviewers, publishers, institutions, and funding agencies to turn peer review into a measurable research output. In the edentulous group, the majority of superstructures in 1990 was fixed prostheses (64%), whereas in 1995 the majority was overdentures (71%). An International Survey among Prosthodontists of the Use of Mandibular Implant‐Supported Dental Prostheses. 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. In all FRC-FPD models, the FRC framework showed stress-bearing capacity for the FPD. Postoperative patient reactions including swelling, discoloration, discomfort, hematomas, and disability were recorded. 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. Data were obtained from patient charts. International Journal of Prosthodontics is a Subscription-based (non-OA) Journal. 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). SCOPE. All patients who received oral implants in 1990* and in 1995 were selected, and their files (95 and 105, respectively) were consulted. 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. These results underscore the importance of panoramic examination of edentulous patients in detecting potential problems before complete denture treatment. The resistance against dislodgment of the denture was low in all three groups. 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. No significant differences were found for type of restoration and distribution in the mouth. 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. 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. Some of the AllCeram crowns were among the very first that were placed. PI and BOP were not directly related to the frequency of failures. The Community Periodontal Index for Treatment Needs (CPITN) was calculated per sextant in a full-mouth assessment. Longer observation periods are necessary before this type of restorative design can be recommended as a general conservative procedure. The main reason for failure was fracture of the ceramic (33.68%). Post hoc analysis revealed that after the storage of 4 weeks no statistically significant reduction occurred. Of these, 35 (25%) were removed after a mean of 11 years in function, which left 75% in place and functioning after 18 years. 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 removal rate for abutments with cast posts and cores was higher than the removal rate of total abutments. The editorial board is composed of a distinguished team of leading international scholars. Finally, acrylic resin tooth veneers were attached on the buccal surface of posterior maxillary teeth to improve the arch discrepancy. During this study period, 14 individuals died, leaving 138 fixed partial dentures to be examined. Twelve clinicians at nine clinics placed 87 crowns in 50 patients. Small restorations in the bonding area did not affect the survival. China Hong-Chang Lai, DDS ...

ICP Newsletter - September 2020. Get this from a library! Results: International Journal of Periodontics & Restorative Dentistry. This study presents a method of using shadow-speckle correlation to reconstruct a 3-dimensional (3D) tooth model. Scanning electron micrographs showed smear layer removal as an immediate effect of air polishing. 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 differences between the three groups were evaluated 6.5 years after treatment. The aim of this clinical retrospective study was to evaluate the clinical quality, estimated survival rate, and failure analysis of different all-ceramic restorations in a long-term analysis of up to 20 years. Publishers own the rights to the articles in their journals. 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 incorporation of virtual engineering into dentistry and the digitization of information are providing new perspectives and innovative alternatives for dental treatment modalities. DNA gel electrophoresis was performed to detect possible genotoxicity and DNA damage. Adaptation problems were ruled out as a possible cause. Endodontic treatment was performed for a low number (2%) of the AllCeram crowns. In the remaining 106 patients (223 implants), 8 implants failed (4 standard and 4 shorter), in type 3 or 4 bone. With respect to the type of superstructures, there was a strong increase in the number of single-tooth replacements (from 4% to 23%). Latest issue: Issue 5/2020. ICP Biennial Meeting. 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. The survival rate of the FPDs was 78%, and the established success rate was 71%. ... Grant Funding, Networking with Global Prosthodontic Leaders and Advocates of Prosthodontics, Free Webinars and more... We Invite You to Join the ICP! Successful sinus membrane water balloon lifting procedures were performed in 26 cases; two procedures were aborted due to sinus membrane perforation. Int J Prosthodont 33 (2020), No. Two implants were lost as a result of suppuration caused by membrane exposure, while another was lost after loading. 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. No fractures or chipping of the restorations occurred within the course of the evaluation. The mean follow-up period was 17.7 years (range: 17.1 to 21.3 years). 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. ICP journal. 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. Int J Prosthodont 2010;23:243-245. The ability to displace gingiva was indirectly measured by the quality of the final impression. Only 6.3% of the impressions were unacceptable and categorized as Criteria III. Patients were offered a supportive maintenance program. MMT decreased by 17% during denture abstention following repeated implant surgery, and returned to 100% during the 12 months with the mandibular IOD. During a mean observation time of 46.57 months, 35 VRFPDs on vital abutment teeth did not exhibit postoperative sensitivity or secondary caries. The outcome is also in agreement with that reported for metal-ceramic crowns. 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;24:356-362. Furthermore we use Google Analytics to create anonymized statistical reports of the usage which creates Cookies too. Odds ratios were 1.00 for both PI and BOP. 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 Journal of Prosthodontics is the official journal of the American College of Prosthodontists.It promotes the advanced study and practice of prosthodontics, implant, esthetic, and reconstructive dentistry. The present report describes a relatively simple but effective prosthodontic treatment following removal of a moderately well differentiated osteogenic chondrosarcoma in the premaxillary region. First, the fossa of mandibular posterior teeth was positioned on the crest of the mandibular edentulous ridge. Implant Treatment with Fixed Prostheses in the Edentulous Maxilla. Provides the worldwide dental community with current, scientifically sound information on patient care, research, and education in prosthodontics and interrelated disciplines. The most common clinical findings were gingival bleeding on probing and appearance of supragingival crown margins. 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). Receiver operating characteristic analysis for all study groups revealed that for age, no clear cutoff point exists with acceptable specificity and sensitivity. Fibers were oriented at a 45-degree angle to the long axis of the test specimens. Official Journal of the International College of Prosthodontists and the International Society for Maxillofacial Rehabilitation. The success rate was determined using Kaplan-Meier survival analysis. The information was imported to and combined in the 3Shape Implant Studio software for guided implant surgery planning. 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. 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. 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. 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. 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. Significantly lower bond strengths were obtained between Panavia and the admixed amalgam alloy. A total of 207 implants were placed in 72 patients, and 182 implants had been uncovered. Author(s): International College of Prosthodontists. This study obtained information on the long-term efficiency of prosthetic rehabilitation with fixed partial dentures performed by undergraduate students. In general, the soft tissue conditions around the restorations were healthy and comparable to those of the patients' natural teeth. The most frequent finding (30.6%) was close approximation of the maxillary sinus to the crest of the ridge. 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. 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. The editorial board is composed of a distinguished team of leading international scholars. Cementation using Variolink showed significantly fewer failures than Optec Cement (P = .0217) and Dual Cement (P = .0099). Get this from a library! The Journal of Prosthodontics promotes the advanced study, science, and practice of prosthodontics, implant, esthetic, and reconstructive dentistry.It is the official journal of the American College of Prosthodontists, the association that represents the dental specialty of prosthodontics. The 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). Two types of implants were used (141 titanium plasma-sprayed and 124 Sand-blasted, large-grit, acid-etched). 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. Materials and methods: Ceramics in Prosthodontics. For the surviving restorations, the improved PI over time was statistically significant (P = .001). 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. Patients were extremely pleased with the results and needed very little medical attention after surgery. Dropouts were recorded for 23 patients with 23 prostheses supported by 42 implants. 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). 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. This paper reports the clinical experience of 47 patients treated for a single-tooth replacement. ACP members must be logged in to access the Journal.. Materials and methods: All-ceramic restorations offer a predictable and successful restoration with an estimated survival probability of 93.5% over 10 years. The results revealed no significant differences in oral stereognostic ability between patients with diagnosed psychogenic dental prosthesis incompatibility and the control patients. The International Journal of Prosthodontics. The success rate for the gold-resin restorations was less favorable: 43% remained unchanged and 33% had been removed. Mats Kronstrom DDS, Odont Dr, PhD; Gunnar E. Carlsson LDS, Odont Dr, PhD; Pages: e622-e626; First Published: 17 March 2017 However, when there were deep subgingival margins and a beveled preparation, the material was less effective than the single cord retraction technique. The 5-year prosthesis cumulative survival rate was 97.1% in the early group and 100.0% in the late group. 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). 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) This study investigated the survival of complete crowns in relation to periodontal variables on a long-term basis. 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. A total of 163 fixed partial dentures were inserted. One implant was lost due to infection. 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. In relation to complete crown survival, caution is needed in patients with a high CPITN at baseline. 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 patient group of < or = 40 years of age had significantly increased, from 7% to 23%. Data provided are for informational purposes only. 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. Bio-Oss was filled under the elevated sinus membrane using a dedicated instrument. The observation period ranged from 1 to 9 years.

The International Journal of Prosthodontics is dedicated to exploring and developing this … Sixty-seven screw-type standard, self-tapping implants and mini-implants were placed. Both groups were followed and evaluated clinically and radiographically for 5 years according to similar protocols. 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 55-year-old Japanese woman received periodontal therapy and cross-arch fixed partial dentures were placed in the maxilla and mandible. Dry test specimens and those stored in water for up to 180 weeks were tested with a 3-point loading apparatus. The 14-year cumulative survival rates for all short and standard implants were 97.9% and 97.1%, respectively. The FRC1 framework also best reduced displacement of the framework. EndNote Styles - International Journal of Prosthodontics. Tumedei, Margherita et al. materials and methods: A three-unit FPD replacing the maxillary right lateral incisor was constructed using FE analysis software (ANSYS 10.0, ANSYS). 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. 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 editorial board is composed of a distinguished team of leading international scholars. They were placed on your computer when you launched this website. Journal of Prosthodontic Research originated as an official journal of Japan Prosthodontic Society. Prosthetic work should be preceded by periodontal examination and prophylactic and periodontal treatment if needed. 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 A total of 1,037 complete crowns made in an undergraduate clinic for 456 patients were evaluated over an 18-year period. 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. No patient complained of food impaction. 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). Conclusion: This could possibly be attributed to a more bioactive implant surface and shorter healing period before implant surgery in the late group. 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. 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. Differences in fit between experimental specimens and custom-made ones showed that experimental results might not always be obtained in clinical practice. Cantilevered IPS e.max Press VRFPDs should be considered a minimally invasive, single-tooth restorative strategy in the anterior or first premolar area. This method has encouraging results, is easy to learn, and is associated with low complication rates. The long-term results were good, especially for the metal ceramic restorations: 79% remained unchanged and only 3% had been removed. The precision obtained with the custom-made crowns differed from that of the experimental specimens. Failures occurred significantly more when endodontically treated abutments were used. The stability of the mandibular dentures as well as the retention were better in group 2 than were those in group 1. You will find more information in our, The International Journal of Prosthodontics. The monthly publication features timely, original peer-reviewed articles on the newest techniques, dental materials, and research findings. 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. However, prescribing such an examination in patients seeking replacement dentures requires a thorough patient history and clinical examination. The study population included 106 (35.1%) individuals diagnosed with bruxism. The less favorable long-term survival of implants in the orbital rim, especially at irradiated sites, requires further study. The study cohort comprised 83 patients with complete dentures fabricated according to a standardized protocol. Purpose: 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 prosthesis length ratio and the crown length-bone ratio did not influence the failure rate. 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) The bone loss was of the same magnitude as in other studies on Brånemark implants as support for single crowns. The crowns were placed between 1989 and 1995. The study cohort comprised 83 patients with complete dentures fabricated according to a standardized protocol. For the CPITN, odds ratios were 3.00 to 3.83. Int J Prosthodont 2011;24:345-355. Implant treatment has been performed for more than 45 years, but there is still limited knowledge on how treatment outcomes are changing over time. 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). Carious lesions were found on 4% of the abutment teeth. Page 487-492, doi:10.11607/ijp.6470, PubMed:32956429 Perceptibility and Acceptability of Color Differences of Single-Tooth Implants at the Restoration … Further, the definition of poor bone quality has changed. After 18 years, STE developed in the left posterior region of the mandible. Of the prosthetic restorations, 165 were all-ceramic (68%), 79 were metal-ceramic (31%), and 4 were gold-acrylic (1%). It was presumed that biomechanical loading in the mandible, along with other factors, might have caused the STE in this particular patient. Failures of the fixed prosthetic restorations were defined as irreversible complications (finish line involved or loss of CCs, FDPs, or abutments). 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. These findings indicate that resin-based dental restorative materials release agents cytotoxic and genotoxic to fibroblasts. 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 number of statistically significant differences was apparent between these 2 periods. The degree of satisfaction was indicated with a visual analog scale. Severe morphologic alterations and pronounced DNA damage were also observed. The aim of the study was to evaluate AllCeram crowns in dental practice over a 5- to 10.5-year period. Dresden, 23-26 May 2002. This is a report on Procera AllCeram crowns in a prospective multicenter study. The purpose of this study was to investigate the distribution of shades selected for metal ceramic crowns provided at a dental teaching hospital. The marginal integrity was considered excellent or acceptable for 92% of the crowns. Control specimens were unreinforced. The clinical performance of 325 resin-bonded fixed partial dentures (RBFPD) placed between 1984 and 1995 was reviewed. Patients receiving artificial crowns and fixed partial dentures at a prosthodontic clinic were examined 18 to 23 years after treatment. Southeastern Academy of Prosthodontics, The Swiss Society of Reconstructive Dentistry Turkish Prosthodontics and Implantology Association, The (Istanbul) (no website) Read more. 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. Nonvital teeth showed a significantly higher risk of failure (P < .0001). A total of 9 patients (10 implants) was lost to follow-up. 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).

Continuous, woven, silanized E-glass fibers and woven silica fibers were used to reinforce heat-cured and autopolymerized denture base polymers. Ultimate transverse strength and flexural modulus of unreinforced and fiber-reinforced composite test specimens decreased during water storage (P < 0.001, analysis of variance). Morphologic changes attributable to cytotoxicity were observed by May-Grunwald-Giemsa cytologic staining and microscopic examination. 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. The results suggest that single-tooth replacement using osseointegrated implants provides predictable success. Editor-in-Chief: George A. Zarb Official journal of the International College of Prosthodontists, International Society for Maxillofacial Rehabilitation, German Society for Prosthodontics and Dental Materials Science, and Italian Academy of Prosthetic Dentistry Volume 26, 2013 Subscription Rates (Includes free Web access to all back issues) ;] Only those crowns placed adjacent to minimally restored vital teeth were included in the study. 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. Conclusion: Prosthetic treatment and maintenance of implant-supported fixed prostheses improved significantly between the groups. 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. This study evaluated the marginal fit of experimental and custom-made fixed prosthetic restorations through a new 360-degree external examination. Mucosal hyperplasia and inflammation showed a trend of higher frequency at implants in the early group of patients (P > .05). 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). 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. Purpose: To establish a complete digital workflow for the design and manufacture of sports mouthguards and to observe preliminary clinical effects. 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. Implant site preparation employed a pilot drill and osteotomy followed by water balloon elevation. The maxillary posterior teeth were then placed palatally to maximize occlusal contacts with the opposing mandibular teeth. 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. The International journal of prosthodontics | Citations: 3,491 | Official Journal of the International College of Prosthodontists and the International Society for Maxillofacial Rehabilitation. A total of 8 crowns was remade following prosthetic complications; otherwise, the frequency of adverse events was low. Anyone who wants to read the articles should pay by individual or institution to access the articles. It is possible to achieve high survival rates of implants in the auricular and piriform/nasal sites through careful presurgical and radiographic planning. 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. A removable partial denture was retained by the attachments and conventional cast retentive circumferential clasps, including a hollow obturator filling the defect. In cases of epigingival and subgingival (< 2 mm) preparation margins, MFC was a less traumatic alternative method of gingival retraction. One major use of ISO 4 is to abbreviate the names of scientific journals. The 5-year overall implant cumulative survival rates were 93.4% and 97.3% for the early and late groups, respectively. Significantly increased failure rates are associated with bruxism, nonvital teeth, and specific cementation agents. Auricular implants showed the highest survival rate (95%), and orbital implants showed the lowest survival rate (53%). Localized high stress concentration was observed around the connectors under all loading conditions. 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 California Dental Association quality evaluation system was used for assessment of marginal integrity and esthetics. This study is the first to use oral stereognosis tests for patients with psychologically diagnosed psychogenic dental prosthesis incompatibility. Although carefully collected, accuracy cannot be guaranteed. Both groups were followed for 5 years with regard to prosthetic treatment, clinical maintenance, and complications. To read the Full Author Guidelines, click here.. 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). The highest stress reduction ratio under all loading conditions was obtained using the FRC1 model. 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. Over the last decade, oral implantology has become a major treatment modality to aid the restoration of reduced dentitions. Ninety-five failures 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.

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. It was concluded that airborne particle abrasion removes the smear layer, and the amount of dentin removed corresponded to the time of application. There was no difference in removal frequency between fixed partial dentures with moderate cantilever extensions and those with end-supported extensions. 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. 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). This report explains how relatively uncomplicated prosthodontic measures can enormously affect quality of life. The patient has kept up with his oral hygiene, using conventional methods for the teeth and prosthesis, with periodic flushing with chlorhexidine solution. Those statements are on file at the editorial office. Mean marginal bone loss and gingival crevice probing depth associated with either implant length were statistically comparable (P> .05). This study confirms the favorable results presented in other studies on Brånemark implants to support single-tooth restorations. Major changes in oral implantology treatments were noticed between the 1990* and 1995 periods at ACTA. No correlation was found between oral stereognostic ability and the SCL-90-R or CES-D values. Group 2 patients scored comparably or higher than the normal ridge group (group 3). There was no relationship between gender and irreversible complications. 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 selection of more than one shade for a crown ("mixed shades") was generally restricted to the maxillary anterior teeth. Furthermore we use Google Analytics to create anonymized statistical reports of the usage which creates Cookies too. Number of restoration failures and reasons for failure were recorded. 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. The patients in the test group expressed clear dissatisfaction with their dentures. 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. 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. Osseointegration has influenced the decision-making process in prosthodontic treatments related to extraction. 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. Clinical examination was performed during patients' regularly scheduled maintenance appointments. 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. Evidence-based dentistry 2006: Where are we? 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. 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). Thus, psychogenic prosthesis incompatibility can be classified more explicitly as a psychosomatic disorder. The results were similar to those for complete and partial osseointegrated prostheses. The remaining 2 lost implants were managed by converting the distal unit of the fixed partial prosthesis to a cantilever. 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 aim of this study was to determine the effect of long-term water immersion on the flexural properties of fiber-reinforced composite. One or more of these radiographic observations were found in 51.7% of the examined films. More mandibular restorations failed than did maxillary units, but the difference was not significant. Baseline bone height was 4.92 +/- 1.24 mm. Endodontic complications on abutment teeth were more frequent in the mandible than in the maxillae. The problem-free use of the appliance can be at least partly explained by the patient taking oral hygiene measures seriously from the beginning. Biologic and technical complications as well as patient satisfaction were recorded. Int J Prosthodont 2011;24:314-319. 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. There was a clear statistically significant association between age and irreversible complications. The reproduction of the preparation finish line and an absence of bubbles or voids (Criteria I through III) were assesed. The results indicate that the most frequently chosen shades were in the mid-range of reddish-brown hue. 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. 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. Periodontal variables were measured, including Plaque Index (PI), bleeding on probing (BOP), probing pocket depth (PPD), and attachment level. The results indicate a good prognosis for Procera AllCeram crowns also for posterior teeth. Median duration was 84 +/- 3.6 months. 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. During the 18 years, 41 (30%) failed. The estimated survival rate was 97.3% after 5 years, 93.5% at 10 years, and 78.5% at 20 years. The majority (85%) of the fixed partial dentures were acrylic resin veneer-gold restorations; 15% were metal ceramic restorations. 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. Author Guidelines. Bleeding was somewhat more often recorded at teeth with AllCeram crowns (39%) than at contralateral teeth (27%). The majority of the reduction occurred during 4 weeks of storage in water and remained approximately at that level for 180 weeks. The patients' complaints with the restorations included taste disorders, odynophagia, pain sensations, and functional and esthetic dissatisfaction. Latest issue: Issue 6/2020. Caries was the most frequent reason for failure, followed by periodontal disease. 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. 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).
