A 24-year follow-up on the surgical correction stability of Class II skeletal malocclusion associated with anterior open bite and temporomandibular joint pain

Abstract

This case report presents a 24-year follow-up of a previously treated Class II malocclusion with an anterior open bite and temporomandibular joint pain. Mandibular advancement with counterclockwise rotation and nonrigid fixation was employed to avoid bimaxillary surgery, given the favorable positioning of the maxilla. Postoperative outcomes revealed significant improvements in occlusion, esthetics, and temporomandibular joint function. Twenty-four years later, the patient still had a stable occlusion, excellent esthetics, and periodontal health. There was no recurrence of temporomandibular disorder symptoms, which demonstrates the treatment’s long-term success.
