Summary

This study is a registry that will collect information from about 200 people who receive a total jaw joint (TMJ) replacement. Researchers will track their health, jaw function, and any complications for up to 5 years after surgery. The goal is to learn more about how these replacements work in real-world settings and to understand why some people choose not to have the surgery.
