中文摘要：

加速牙齿移动是近年来正畸医生关注的焦点之一。其中牙周辅助加速成骨正畸治疗（periodontally accelerated osteogenic orthodontics,PAOO）技术被证实可有效加速牙齿移动。该技术以局部加速现象为理论基础发展而来,术式在其发展的几年间也几经改良。目前认为PAOO技术可以加速牙齿移动,缩短疗程,减少牙根吸收,增加牙槽骨量,可获得差异性牙齿移动,同时增强术后稳定性。本文阐述PAOO技术的发展历史及加速牙齿移动机制,介绍其目前临床研究和临床应用的现况,可让读者对PAOO技术有较全面的了解和认识。

英文摘要：

Recently,accelerating orthodontic tooth movement has been one of focus for orthodontist. Previous study have found that periodontally accelerated osteogenic orthodontics（ PAOO） can effectively accelerate orthodontic treatment. Based on the regional acceleratory phenomenon（ RAP）,this technology has been improved in the past few years. PAOO has several advantages,including acceleration of tooth movement,reduction of treatment time,less root resorption,enhancement of alveolar thickness,differential tooth movement and more post-orthodontic stability. This paper provided an overview of the history and mechanism of PAOO. Current clinical studies and clinical application were also introduced to let the readers have more comprehensive understanding of PAOO.
