Influence of Diameter of FGM Implant on Stress Distribution

Development of new materials such as functionally graded material FGM for dental implant applications have been recently received significant attention due to their abilities to satisfy both biocompatibility and mechanical properties simultaneously. The goal of this research is to evaluate the influence of implant diameter dimension on stress distribution around dental prosthesis. For this purpose, an axisymmetric finite element model of the implant and the jaw bone is constructed. The finite element model of implant, cortical bone and cancellous bone is constructed in Abaqus software. The implant body is made of FGM, which is a mixture of titanium (Ti) and hydroxyapatite (HAP). The implant diameter varied as different values so according to material properties of FGM and implant diameter dimension, stress distribution are investigated. Functionally graded material are used to reduce stress concentration in implant, trabecular and cortical bones and to improve biocompatibility.
