The Method of Analyzing the Reliability of Tooth Surface Contact Strength Based on Finite Element Method and Weibull Distribution

Abstract:

In this paper, a method of analyzing the reliability of tooth surface contact strength was presented and several kinds of errors of tooth shape were taken into consideration. In the method, experimental design method and Finite Element Method (FEM) were used to get the samples of tooth surface contact stress, and then Weibull distribution was used to fit these samples. On the basis of both stress and strength obeying to Weibull distribution, the reliability of tooth surface contact strength was calculated. The result of the calculation example indicates that the method is correct and effective.
