近年来，国内外一些正畸医师采用骨皮质切开术辅助加速正畸牙移动以缩短治疗时间。骨皮质切开后快速牙移动的理论基础与局部加速现象相关。动物实验和临床研究证明该技术可以使正畸治疗时间缩短为传统治疗时间的1／2～1／3，并且牙根吸收减少，牙槽骨量增加，且复发较低，适用于大部分错牙合畸形。尽管骨皮质切开加速牙移动有诸多优点，但尚不能作为临床常规治疗方法，对其长期疗效和安全性还缺乏完善的临床随机对照试验。“,”Accelerating the rate of tooth movement is desirable to patients because it shortens treatment time.Currently,some orthodontists use corticotomy to speed up tooth movements .Corticotomies induce the regional acceleratory phenomena,which provides the biological basis for accelerated tooth movement .Animal research and clinical studies show that orthodontic treatment time with this technique can be reduced to 1/2-1/3 of the time of conventional orthodontic with less root resorption ,increased bone support,and low relapse , which is adapted for most malocclusions.Based on the available literature,performing corticotomies on a rou-tine basis may not be justified ,since random controlled clinical studies are still needed to understand the long term efficacy and safety.
