Aim: The aim of this study is to evaluate the flexural strength of zirconia using three different connector designs under vertical and oblique loads. Setting and Design: Invitro - analytical study. Materials and Methods: For simulating zirconia fixed partial prosthesis, a specimen with three octagonal cylinders connected with each other was designed. Each face of the octagon was 3.75 mm ± 0.1 mm, and the total width was 9 mm ± 0.1 mm with a standard connector area of 10 mm2 at cross-section. Three different connector designs, i.e., round, oval, and triangular were milled. Universal testing machine was used to test flexural strength with vertical and oblique forces. Statistical Analysis Used: Intergroup comparison of flexural strength was made using Descriptive statistics (1) one-way ANOVA, Bonferroni's post hoc test (2) Kruskal–Wallis test. The confidence interval was set at 95%, P < 0.05 was considered statistically significant for both the tests. Results: The highest flexural strength was observed in the triangle connector with vertical forces and lowest with oblique forces. Conclusions: Triangle connector design proved to be better than round and oval connectors on the application of vertical loads. Round connector design proved to be better than triangle and oval connector on application of oblique loads.
