Design and Finite Element Analysis of Patient-Specific Total Temporomandibular Joint Implants

In this manuscript, we discuss our approach to developing novel patient-specific total TMJ prostheses. Our unique patient-fitted designs based on medical images of the patient's TMJ offer accurate anatomical fit, and better fixation to host bone. Special features of the prostheses have potential to offer improved osseo-integration and durability of the devices. The design process is based on surgeon's requirements, feedback, and pre-surgical planning to ensure anatomically accurate and clinically viable device design. We use the validated methodology of FE modeling and analysis to evaluate the device design by investigating stress and strain profiles under functional/normal and para-functional/worst-case TMJ loading scenarios.

Automated summary

This manuscript discusses the development of patient-specific total TMJ prostheses. The design is based on medical images of the patient's TMJ, offering accurate anatomical fit and better fixation to the host bone. The prostheses have special features that potentially improve osseo-integration and durability. The design process takes into account surgeon's requirements, feedback, and pre-surgical planning to ensure accurate and clinically viable device design. The design is evaluated using FE modeling and analysis to investigate stress and strain profiles during TMJ loading scenarios.
