Evaluation of arthrographically assisted splint therapy in treatment of TMJ disk displacement.

Eighty-two patients with audible clicking were evaluated and treated with splints made by using arthrographic assistance. In the course of this study, it became apparent that the later the opening click, the earlier the closing click. It was not always possible to auscultate or palpate either an opening or a closing click in many patients with arthrographic findings of disk displacement with reduction. Since the opening click was the only audible sound in some patients, clinical judgment alone cannot be used to replace the displaced disk at an optimal mandibular position. The elimination of the opening click does not always signify recapture of the disk. Maxillomandibular and incisal relationships limit the amount of protrusion possible to recapture the displaced disk.
