Abstract: Stress transformation from fixed partial denture to dental implant and distribution to surrounding bones is an essential factor in long term survival rate of prosthesis. The main objective of this study was to analyze the effect of a newly developed material (Trinia) and the conventional Zirconia implant-supported fixed partial dentures on stress transformation and distribution in the surrounding bone of dental implants. For this purpose, 3D finite element models of implant supported fixed bridge with surrounding bone were developed and simulated for both Trinia and Zirconia materials subjected to static loading. The results showed that the occlusal load transformed through Trinia and distributed to supporting bone was greater in premolar and molar regions compared to zirconia. This study demonstrates that using different material for fabrication of implant supported bridges directly affects the stress distribution in the peripheral bone which can enhance the knowledge in clinics to improve longevity of prosthesis.
