Finite element bite force two-body wear analysis of the titanium-based dental biomaterials

Abstract

Background: It has become an increasingly important issue to be able to predict the behavior of biomaterials placed in the human body over the time periods. It is always desirable for the biomaterial to have the ability to show the desired mechanical and esthetic behaviors throughout the determined treatment process. Researchers develop many laboratory and modeling test mechanisms to determine the behavior of biomaterials over time periods. The aim of this study is to perform computer-aided analysis of the mechanical behavior of titanium biomaterial, which is frequently preferred in the human body, under different chewing forces. Materials and Methods: In this study, 20N, 40N, 60N, 80N, and 100N chewing forces were applied to the titanium test specimen prepared in the cylindrical shape. The chewing load analyses obtained after the test were evaluated by comparing with the previous experimental study (mean chewing force as 50N). Results: With the data obtained as a result of this study, it was observed that more plastic deformation occurs when the chewing force increases. It has been predicted that an increased wear area may occur in the test material due to the movement of the chewing mechanism. Conclusion: It can be said that choosing the average chewing force in experimental studies contributes to the occurred of less wear areas on the test material compared to the random chewing forces test procedures.
