Adult Rhesus monkeys were used as experimental models to investigate revascularization and bone healing in different single‐stage anterior, posterior and total maxillary osteotomy techniques. Microangiographic and histologic studies demonstrated that intraosseous and intrapulpal circulation to the mobilized maxillary segments were maintained by the experimental flap designs which maintained intact soft tissue; the fragments healed by osseous union within six weeks without immobilization of the mandible. The treatment of many severe dental‐facial deformities is difficult and challenging. Functional and stable occlusions with facial balance and harmony have been attained in many adult patients by maxillary osteotomy techniques. The Rhesus monkey serves as an excellent experimental model to develop new biologically sound maxillary surgical orthodontic techniques.
