Orthodontic tooth movement inevitably affects adjacent periodontal tissue. The labiobuccal alveolar bone is generally thin, and patients with dental crowding often present alveolar dehiscence and fenestration. These may lead to prolonged treatment time, even gingival atrophy, tooth loosening and other complications in the orthodontic tooth movement. Periodontally accelerated osteogenic orthodontics (PAOO) could accelerate the orthodontic tooth movement and promote the formation of new bone by using corticotomy and bone grafting. This article, starting from the influence of orthodontic treatment on periodontal hard tissue, describes the application of PAOO in orthodontic treatment.牙齿的正畸移动必然伴随邻近牙周组织的改变。牙齿唇颊侧的骨板普遍较薄，且牙列拥挤患者常伴唇颊侧骨开裂或骨开窗。这些情况可能导致牙齿无法在预期时间内移动到理想的位置，甚至在移动过程中发生牙龈萎缩、牙齿松动等并发症。牙周辅助加速成骨正畸（periodontally accelerated osteogenic orthodontics，PAOO）通过切开骨皮质，联合植骨技术，加速牙齿的正畸移动，促进形成新的牙槽骨，可缩短正畸周期并减少并发症发生的可能性。本文从正畸治疗与牙周硬组织的关系出发，介绍PAOO在正畸治疗中的应用。. |
