Osteoarthritis of the temporomandibular joint causes marked retrusion of the mandible and open bite. To date, several surgical orthodontic treatment modalities have been performed, but prognosis and postoperative stability are poor, because of relapse and condylar resorption. Mandibular autorotation concept (MAC) surgery performed at our hospital is a broad term to describe the series of orthognathic surgery utilizing an intentional mandibular autorotation. In this presentation, I would like to share with you the backgrounds and effectiveness of the MAC surgery with the basic and clinical data.

Learning Objectives:

  • Explain the backgrounds of orthognathic treatment of mandibular retrusion and open bite due to condylar changes.
  • Recognize the rationales to propose the orthognathic treatment using mandibular autorotation concept (MAC) surgery.
  • Evaluate the reproducibility and stability of orthognathic treatment using MAC surgery.
