Bilateral ankylosis of the jaw treated with total alloplastic replacement using the TMJ concepts system in a patient with ankylosing spondylitis.

Minimal documentation exists regarding bilateral temporomandibular joint (TMJ) involvement in ankylosing spondylitis (AS) and surgical management of this specific manifestation. Use of TMJ concepts prostheses in AS patients has not been previously described. This case demonstrates that TMJ replacement with prosthetic joints in AS is technically possible and appropriate.
