Abstract
Abstract Background: The thermal changes environment is a parameter that affects the dental mechanical and esthetic behavior of materials. Dental materials placed in the human oral environment are inevitably exposed to thermal changes environments during chewing movement and hot or cold fluids. Aim: Therefore, this study aims to analyze the surface behavior of a dental material placed in the human mouth in thermal changes according to the finite element method. Materials and Methods: Cylindrical titanium alloy samples with a diameter of 12 mm were prepared for thermal shock load simulation. Withinthe scope of this study, the samples were divided into two equal groups. While the first group test samples were subjected to thermal shock experiments, the others were determined as the control group. The surface temperature distributions of the samples in the test procedures were analyzed and evaluations were made on the wear behavior of the materials. Results: The temperature distributions showed density on the material surface and it was analyzed that a temperature transfer took place toward the inside of the material. Conclusion: This result is evaluated as behavior that reduces the wear resistance since it directly affects the contact surface in the two-body (direct-contact) wear mechanism.
