DENTAL PROSTHESIS;

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.
