The use of an anatomic articulator in segmental orthognathic surgery

We have tried to discuss briefly the pertinent theory, mechanics, and clinical use of an anatomic articulator in segmental orthognathic surgery. Many of the concepts and clinical uses of the articulator may be applicable to the full range of orthognathic surgical procedures. Many of the ideas presented here may seem needlessly detailed or irrelevant to the uninitiated. It is this attention to details and thoroughness that ultimately determine how closely our treatment will achieve the "ideal" functional and esthetic goals. We must measure the effectiveness of an anatomic articulator by the three original goals of maxillary segmental surgery: 1. Improvement of the patient's esthetic and facial harmony. 2. Improvement of the centric and functional occlusal relationships. 3. Maintenance of the long-term health and function of the teeth, periodontium, temporomandibular joints, and associated structures. I believe that these three criteria will be more closely achieved by the use of an anatomic articulator in segmental maxillary surgery. If the orthognathic surgeon is to be more than a technician performing prescription surgery, a thorough knowledge of the functional stomatognathic system is essential.
