In combined orthodontic-orthognathic treatment, the maxillary palatine suture is closed in most patients with insufficient maxillary width, and bony expansion of the maxilla cannot be achieved by dental expansion or rapid palatal expansion (RPE) which causes buccal inclination of the maxillary posterior teeth leading to unstable results. Therefore, segmental LeFort Ⅰ osteotomy and surgically assisted RPE are often used in clinical practice. In recent years, with the application of implant anchorage technology, implant anchorage assisted RPE has been gradually applied in orthognathic treatment. This article reviewed the indications, contraindications, complications, efficacy and long-term stability in different treatment approaches including segmental LeFort Ⅰ osteotomy, surgically assisted RPE and implant-supported maxillary skeletal expansion.
在正畸-正颌联合治疗中，大多数上颌宽度不足的患者会闭合上颌腭中缝，通过牙齿扩弓或快速腭中缝扩展（RPE）无法实现上颌骨的骨性扩展，这会导致上颌后牙颊倾，从而产生不稳定的结果。因此，临床实践中常采用节段性LeFortⅠ型截骨术和外科辅助RPE。近年来，随着种植支抗技术的应用，种植支抗辅助RPE已逐渐应用于正颌治疗。本文综述了节段性LeFortⅠ型截骨术、外科辅助RPE和种植体支持的上颌骨骨骼扩展等不同治疗方法的适应证、禁忌证、并发症、疗效及长期稳定性。
