Orthodontic treatment for the patients with TMJ internal derangement with clicking

Clinical Report of Cases with Angle Class II, division 2 malocclusions

Abstract

Orthodontic treatments were applied in five cases of TMJ internal derangement. Two cases of TMJ internal derangement with clicking, treated by orthodontic treatment are presented. Case 1 was a 14-year-old male who had a clicking sound in left TMJ, and who primarily received repositioning splint therapy. However prosthetic reconstruction of the occlusion was difficult because of severe crowding of the teeth. Case 2 was a 15-year-old female with rotation of the upper central incisors which seemed to induce disturbance of the TMJ anterior movement. Thus orthodontic treatments by the multibracket system were performed. After the treatment, the patientshad no TMJ symptoms, and any recurrence has not been noted at either the 10-month and 20-month follow -up. Selective orthodontic management of malocclusion in partients with internal derangement is therefore recommended as an appropriate treatment in non-surgical therapy for TMJ derangements.
