Abstract This is a case report of posterior displacement of the right articular disc. This dislocation was identified by using our functional analyzing system and the lateral section of double contrast CT. The treatment for this case was as follows: The patient was instructed to close and bite firmly on the occlusal splint which provided a single posterior contact on the affected side, and pivoted the condyle downward-backward around the pivoting point. After complete recapture, all first premolars were extracted and multi-bracket direct bonding was performed for orthodontic occlusal reconstruction. In the retention period, the disc-recaptured vertical dimension was maintained by the extrusion of the posterior teeth, and the symptoms of the patient's TMJ completely disappeared.
