A Clinical Evaluation of Onlay and Inlay in the Posterior Ceramic Restorations: An Original Study.

Introduction: The extensively damaged teeth can be treated with the inlay and onlay. The ceramic inlays and onlays can be prescribed for the esthetic needs of the patient. Hence in our study, we aim to evaluate clinically the outcomes of the ceramic inlays and onlays for the posterior teeth. Materials and Methods: We piloted a retrospective analytical study from the departmental records. We included 70 patients who had a total of 160 ceramic inlays and onlays prepared between the years 2010-2020. The survival and the failure rates were noted and compared using the "Kruskal-Wallis H statistics and the Chi-square tests" deliberating P < 0.05 as significant. Results: The mean survival was 6.1 ± 1.8 years. The success rate was 92.21% and the failure was 7.6%. Significant variation was seen with the survival rate between the vital and nonvital teeth and between the molars and premolars. Conclusions: The ceramic inlays and onlays were performed successfully in the posterior teeth with a high survival rate and very low failure. [ABSTRACT FROM AUTHOR]
