A functional approach to the treatment of temporomandibular joint internal derangement.

The goal of treatment for temporomandibular joint internal derangement has traditionally been the anatomic reduction of the displaced disc. Recent magnetic resonance imaging postoperative studies suggest that successful treatment may require only the mobilization of the adhered disc and release of capsular restraints rather than anatomic reduction. It is hypothesized that this mobilization of fibrosed and inflamed tissues decreases load concentration and allows pain-free function through physiologic adaptation.
