Introduction: Fixed dental prostheses (FDPs) are still preferred owing to theirdurability, esthetics, cost-effectiveness, adequate retention and lack of a surgical procedure.These restorations generally demonstrate longer life and durability in clinical service. Despitethe high survival rates, FDP complications are frequently encountered. Although severalstudies have reported on complications associated with FDPs, there is a lack of a standardand universal reporting system for FDP failures. Objectives: To evaluate FDP failures using aneasy classification scheme relevant to all conventional FDP failures. To assess the prevalenceof FDP failures based on this system. Study Design: Cross-sectional study. Setting: MargallaInstitute of Health Sciences (MIHS), Rawalpindi. Period: From 20th July 2014 to 20th January2015. Materials and Methods: Subjects reporting to the outpatient department with complaintsof failed crowns or bridges were included in the study. FDP failures were classified accordingto Manappallil’s classification. Data was analyzed using SPSS version 24. Descriptive statisticswere calculated. Results: Majority (31.6%) of the FDP failures were classified as Class I failureswhile the second most common FDP failures belonged to Class IV with a prevalence of 30.1%.Majority of the study subjects had been wearing FDPs for a period of 2 – 5 years while a few(2%) reported a history of use of FDP for more than 15 years. Conclusion: Class I failures arethe most prevalent failures in FPDs.

The aim of this study was to evaluate the clinical performance of the composite pressed on metal framework for full-arch implant-supported fixed prosthesis in order to eliminate the drawbacks related to the chipping of porcelain fused to metal or to zirconia restorations. Sixteen patients received 22 implant-supported screw-cement-retained complete-arch restorations, consisting of composite pressed restorations. All patients were follow-up visit up to 2 years on function (range 24 to 30 months, mean 28.3 months). The outcomes were implant and prosthetic survival rates and calculations of wear determination (mm). After two years of function, the wear values were 95.54�6.88 mm on pressed composite restoration. Using composite pressed restorations appears to be a predictable, esthetic and successful treatment option for method of full arch restorations over implants.

Objectives. The aim of this retrospective study was to evaluate the three-year clinical outcome for ceramic-veneered zirconia fixed dental prostheses (FDPs). Methods. All patients who were treated with ceramic-veneered zirconia FDPs, in three private practices in Sweden, during the period June 2003 to April 2007 were included. Case records from 151 patients, treated with a total of 184 zirconia FDPs (692 units), were analysed for clinical data. All complications noted in the charts were registered and compared to definitions for success and survival and statistical analysis was performed using the Kaplan-Meier method and a Cox regression model. Results. In total, 32 FDPs in 31 patients experienced some type of complication (17.4% of FDPs, 20.5% of patients). Core fractures occurred in two (1.1%) FDPs. Two (1.1%) FDPs or 0.6% of units showed adhesive veneer fractures. Cohesive veneer fractures occurred in 10 (5.4%) FDPs (1.6% of units). The three-year cumulative success and survival rates (CSR) were 82.3% and 95.2%, respectively. Conclusions. Ceramic-veneered zirconia is a promising alternative to metal-ceramic FDPs, even in the posterior area. However, the higher survival rate of metal-ceramic FDPs should be noted and both dentists and patients must be aware of the risks of complications.

Our purpose was to evaluate the occurrence of complications and the degree of bone loss in a cohort of patients treated with fixed prostheses supported by immediately loaded dental implants. The primary aim was to compare partial versus full-arch fixed dental prostheses. We then tested the effect of sinus lifting. In the present retrospective cohort study, the patients had their implants restored with fixed dental prostheses supported by dental implants positioned in the posterior maxilla and mandible. When necessary, the maxillary sinuses were grafted with particulate autogenous bone. Patients were then ranked according to the following predictors: length of prosthesis, crown-to-implant ratio, number of crowns to number of implants ratio, and presence of sinus lifting. Outcomes were evaluated for up to 2 years regarding the peri-implant marginal bone loss and implant/prosthesis survival rates. Fifty-eight subjects (209 implants) were rehabilitated with 25 fixed full-arch prostheses and 33 partial fixed dental implant bridges (16 supported by implants placed in grafted sinus). The mean marginal bone loss for implants supporting partial fixed dental prostheses amounted to 0.81 mm, whereas that for implants within the group of full-arch fixed dental prostheses was 1.21 mm; the comparison of the levels in the 2 groups showed a significant difference (P = .0055). A statistically significant difference (P = .0006) was found between the bone loss around maxillary implants (1.53 mm) and the bone loss around mandibular implants (1.10 mm). Two implants and 4 prostheses failed; 2-year survival rates of partial and of full-arch fixed dental prostheses, respectively, were 94.1% and 96%. Bone loss in full-arch prostheses appeared to be higher than in that of partial prosthesis. Implant-supported prostheses in the maxillae exhibited a bone loss higher than that registered in mandibles.
