Orthognathic surgery: combined maxillary and mandibular alveolar osteotomies with variations of surgical modalities.

In two patients undergoing alveolar osteotomies, occlusal and functional relationships were maintained after surgery by prefabricated arch bars. Alveolar osteotomies were performed in two patients. The use of prefabricated maxillary and mandibular arch bars maintained occlusal and functional relationships and eliminated the need for intermaxillary fixation and a long period of immobilization.
