Effect of Antagonist Material Geometry on Titanium Biomaterials Two-Body Wear Behavior; Finite Element Analysis Study

Abstract

In recent years, the Finite Element Analysis method has been preferred due to its many advantages such as mathematical modeling, short time, and more experimental parameters. This study aimed at finite element analysis of two body wear behavior titanium-based biomaterial under chewing test procedures. Pure titanium test material was subjected to a 6 mm cylinder and 6 mm length square geometry antagonist abrasive material, 50 N bite force, 2 Hz chewing frequency, 0.7 mm lower jaw movement, finite element analysis chewing process. As a result of this study, force distributions occurred in the wear area of the test material in the chewing test mechanisms performed with both antagonist abrasive materials. However, the chewing bite load distribution from the cylindrical antagonist material showed a more homogeneous behavior compared to the square antagonist material. Additionally, stress concentrations were observed in certain regions of the square antagonist abrasive material. This may cause the test material to suffer from excessive wear and volume loss and damage may occur due to different deformation mechanisms.
