Condylar resorption results in significant mandibular retraction and open bite. To date, surgical orthodontic treatment planning for distraction osteogenesis of the shortened ramus mandible, advancement of the mandible and counter-clockwise rotation have been selected, but prognosis and postoperative stability of these treatments are poor, and they are known to cause relapse with further condylar resorption. Although finding the method to avoid relapse has been a challenge for many years, a paradigm shift is considered necessary to solve the problem. In this presentation, I would like to discuss with you the effectiveness of orthodontic-orthognathic management of Class II patients with anterior open bite caused by condylar resorption with basic and clinical data.
Learning Objectives:
After this lecture, attendees will be able to:
Define the morphological and physiological backgrounds of Class II patients with anterior open bite caused by condylar resorption.
Recognize the morphological change in the condyle and upper airway.
Propose the significance of mandibular autorotation in the treatment of Class II patients with anterior open bite caused by condylar resorption.
