Abstract

A dental implant is considered as the best treatment when dealing with the loss of teeth. It gives beautiful results and can last longer than most of other treatments. Osseo-integration period is a critical period for implant stability. The material used for dental implants is one of the most important factors affecting the stability so using Functionally Gradient Material (FGM) can help improve the stability. In this study, several models for dental implants were analyzed by ANSYS 15.0 APDL. The FGM was considered in three models. The same materials, Ti-HA, were used in all of them but with different geometrical parameters. The natural frequency and mode shapes were extracted for all models and then the harmonic analysis was performed to study the frequency responses for the different models. It was noticed that all the extracted results for FGM vary between the two basic materials, and it is affected by the concentration of each. It is firmly believed that FGM is the future of dental implants due to its ability to design a specific material property for more stability.
