Abstract
Background & Objectives: The objective of this in-vitro study was to compare and evaluate the fracture resistance of posterior teeth restored with Ceramic inlay and Hybrid composite restoration. Methods: Thirty intact, non-carious, human maxillary premolar teeth that were collected. The thirty teeth were randomly divided into 3 experimental group of 10 teeth each , Group A, Group B and Group C. Group A was consisted of sound/unprepared teeth (control). In Group B mesio-occlusal Class-II cavity was prepared in each tooth and restored with Hybrid composite resin. In Group C mesio-occlusal Class-II inlay cavities were prepared and restored with Ceramic inlays. Thereafter, the specimens all three groups were individually tested in a universal testing machine. All specimens were loaded by compression force until the specimens fractured. The ultimate fracture load was recorded. Data collected by experiments were computerized and analysed using Statistical Package for Social Sciences (SPSS) version 17.0. Statistical analysis was done using Unpaired student’s t test. Results: The results showed that Group C had highest kilo newton (KN) values for fracture resistance compared to Group B . Null hypothesis was rejected as fracture resistance of Group C was significantly higher than Group B . However, Group A and Group B did not differ significantly in fracture resistance from eachother. Between Group C and Group A the average kilonewton (KN) value for fracture resistance for Group C was significantly higher than Group A. Conclusion: From this in-vitro study it can be concluded that adhesively bonded restorations such as composite and ceramic inlays are good and optimal replacement for lost tooth structure.Ceramic inlay is better restorative alternative as compared to direct composite resin as far as the fracture resistance is concerned.
