Joint replacement surgery involves the replacement of part or all of the TMJ. This procedure is reserved for severe cases where other options have been unable to restore function. Techniques involve using alloplastic (synthetic) materials. Current technological advances provide patient-specific, custom-made joint parts. Find out more information at TMJ Concepts. The procedure is done in the hospital under general anesthesia and a hospital stay is usually required. Find out how we plan these cases with virtual surgical planning.
