Temporomandibular Joint Total Joint Replacement TMJ TJR

From Dentistry Made Simple Dentistry Made Simple

A comprehensive overview of Temporomandibular Joint Total Joint Replacement (TMJ TJR), focusing heavily on the history, materials science, surgical techniques, and complications associated with these alloplastic devices. A significant portion of the discussion addresses material failures due to wear, such as with polymethylmethacrylate, silicone rubber, and metal-on-metal articulations, leading to inflammation and osteolysis. The sources extensively explore the development and advantages of custom patient-fitted TMJ TJR devices over stock components, particularly for complex anatomies or failed previous surgeries. Furthermore, the text details the protocols for concomitant TMJ TJR and orthognathic surgery, managing complications like periprosthetic joint infection and chronic pain, and the future promise of tissue engineering/regenerative medicine in creating biological TMJ components.
