牙周辅助加速成骨正畸治疗技术

Periodontally accelerated osteogenic orthodontics

治疗周期长是影响成人是否接受正畸及术后并发症发生的重要因素之一。加速正畸牙移动,缩短治疗时长,是患者及临床医师共同的要求。目前,在正畸治疗中可辅助使用外科手术、局部或全身用药、低能量激光等方法减小牙齿移动阻力从而加快牙齿移动速度,其中以局部加速修复现象为理论基础的牙周辅助加速成骨正畸治疗(PAOO)因具备将治疗时间缩短为传统正畸疗程的2/3、减少牙根吸收、增加牙槽骨骨量、术后美学效果更加可控及术后稳定性更好等卓越优势受到了广泛关注。本文就PAOO的发展历史、生物学基础、临床应用及治疗效果等作一综述。

Long duration is one of the most important factors which keep adults from orthodontic treatment. How to accelerate orthodontic tooth movement and shorten the treatment time is a common goal for both patients and clinicians. At present, it is viable to reduce the residence of tooth movement through medications, low-level energy laser therapy, pulsed electromagnetic fields, and osteogenic techniques. Based on the theory of regional acceleration phenomenon, periodontally accelerated osteogenie orthodontics （PAOO） have outstanding advantages over conventional orthodontics, including the reduction of treatment duration, less root absorption, augmentation of alveolar bone, more predictive esthetic effects and more post-orthodontic stability. This article reviews the history, biological mechanisms, clinical application and treatment outcomes of PAOO.
