Background: Fixed partial dentures (FPDs) fabricated from zirconium dioxide (ZrO2) have gained popularity due to their esthetic appeal and mechanical properties. Connector design plays a crucial role in the flexural strength of such prostheses. Materials and Methods: In this in vitro study, three different connector designs – conventional, modified, and adhesive – were assessed for their impact on the flexural strength of ZrO2 FPDs. Thirty samples were fabricated for each connector design using standardized protocols. Flexural strength was evaluated using a universal testing machine, and the results were statistically analyzed. Results: The mean flexural strengths for the conventional, modified, and adhesive connector designs were 300 MPa, 320 MPa, and 340 MPa, respectively. Statistical analysis revealed a significant difference (P < 0.05) between the adhesive connector design and the other two designs. Conclusion: The adhesive connector design demonstrated superior flexural strength compared to the conventional and modified designs. This suggests its potential for enhancing the longevity and durability of ZrO2 FPDs. Further clinical studies are warranted to validate these findings.
