Comparison of stress distribution of implant-supported and tooth-supported fixed partial dentures using finite element analysis.

The finite element method (FEM) is nowadays widely used in dental research. While using FEM; it is important to have a three dimensional digital imaging. The purpose of this study is to compare stress distribution of cement-retained implant-supported and tooth-supported fixed partial dentures using finite element analysis in a three dimensional digital imaging.FEM stress analysis is a method widely used in engineering. Recently it has begun to used in dentistry. Static variables are usually mentioned in the literature. In this study, intraoral situation is transferred to the computer by a 1/1 dijital imaging device newly received to our faculty, so we can look at the possibilities of dynamic variables.In this study, we will look at the differences between the chewing forces that 3 and 5 unit tooth and implant supported dental prostheses overcome. The dijital records of treated patients will be taken and then the models of the jaws will be obtained. These models show the intraoral dynamic nature. The models will be exposed to the chewing forces in computer by using finite element analysis method after that the resistance of the models will be compared. Although not enough resources in the literature, finite element analysis is very popular so we considered the necessity of such a study.Key Words : 1. Finite Element Analysis 2. Dental Implant 3.
