This is a case report of a lateral displacement of the left articular disc. The patient was a 24 year old man who complained of left TMJ pain, clicking and limitation in opening his mouth. An examination showed that the mandible was shifted to the right. A double contrast CT disclosed a lateral sideways disc displacement on the frontal and lateral section of the TMJ. This case was diagnosed as a malocclusion with lateral displacement of the left articular disc. Arthroscopic suturing for disc recapture was selected as the treatment, because the patient's TMJ symptoms had not resolved with splint therapy. After surgery, the symptoms of the patient's TMJ completely disappeared and the mandible was repositioned 2mm to the left. Consequently, orthodontic occlusal reconstruction was performed with multi-bracket direct bonding at the disc-recaptured mandibular position.
