成年恒河猴作为实验模拟物，研究上颌全截骨术后血管重建、血管重建和骨愈合的相关情况。微血管造影和组织学研究显示短暂性血管缺血极少，骨坏死极少，骨愈合早期。腭大动脉的横断对上颌骨的牙齿和骨骼及其周围软组织的循环没有明显的影响。动物实验和临床研究结果表明，腭黏膜和唇颊牙龈为单期上颌全截骨提供了足够的营养蒂。
Adult rhesus monkeys were used as experimental analogues to investigate vascularization, revascularization, and bone healing associated with total maxillary osteotomy. Microangiographic and histologic studies showed minimal transient vascular ischemia, minimal osteonecrosis, and early osseous union. Transection of the greater palatine arteries had no discernible effect on the circulation to the teeth and bone in the maxilla and its enveloping soft tissues. The results of experiments in animals and clinical studies indicate that palatal mucosa and labial-buccal gingiva provide an adequate nutrient pedicle for single-stage total maxillary osteotomies.
