Abstract

This study focuses on the design optimization of temporomandibular joint (TMJ) prostheses, evaluating three model iterations to assess stress distribution, strain behavior, and safety factors. The models were subjected to topology optimization to reduce stress concentrations, enhance structural integrity, and improve overall performance. The third model, which incorporated a reduced volume and modified joint geometry, showed significant improvements with a maximum stress of 143.16 MPa and a safety factor of 3.13, exceeding the required minimum safety factor of 2.0. Additionally, the third model's volume was reduced by 29.2%, resulting in minimized stress-shielding effects. Strain analysis revealed that the third model achieved a more uniform strain distribution with a peak strain of 772.54 μ. These results align with previous research while demonstrating superior performance in terms of safety and stress mitigation. This study highlights the importance of topology optimization in enhancing TMJ prosthetic designs for improved biomechanical performance and patient safety.
