Impact Wear Stress Distribution and Total Deformation on Dental Material under Chewing Cycles

Abstract

Background: The finite element solution estimates have been improving in recent years in biomedical applications. This method provides many advantages to researchers such as specimen force distribution, total deformation, and strain energy. The data obtained after the experimental methods can be examined for the finite element solutions. Aim: Thus, this study aims to a finite element study of total deformation and strain energy on dental material under chewing impact force simulation after experimental study; prediction of maximum and minimum stress distribution. Materials and Methods: In this study, impact wear stress distribution and total deformation analyses were performed on test samples with different geometries. A cylindrical specimen with a diameter of 12 mm and a square geometry specimen with a size of 8 mm was designed for chewing test procedures. The chewing force was applied to the samples over a while and the effect of this force on the wear surface of the sample was investigated through chewing test procedures. Results: In this study obtained data, the chewing force showed a more homogeneous distribution in the cylindrical sample than in the square sample. Conclusion: In addition, it was observed that the concentration of strength mechanism was present at the time of the maximum chewing force of the sample with square geometry.
