14、icotomy-assisted orthodontic treatment (CAOT) 47精选ppt课件发展过程1893年Bryan 提出骨皮质切开加速牙齿移动这一概念。1959年Kole等首先应用了骨皮质首先应用了骨皮质切开术结合根尖下截骨术，证实能够有效加快正畸牙齿的移动。2001年Wilcko等提出了牙周加速成骨正畸(periodontally accelerated osteogenic orthodontics, PAOO ) 的新理念，主要通过切开正畸牙牙根周围颊侧骨皮质至骨髓质深度，并在切开骨表面放置可吸收人工骨材料以增加骨量。48精选ppt课件理论基础骨块移动理论（bon

15、e block theory）：颌骨骨皮质切开加速正畸牙齿移动的理论基础早期在手术中于牙齿近远中颊舌侧骨板进行骨皮质切开，保留骨松质的连续性，通过根尖下截骨术连接骨皮质切口以形成完整牙骨块， 他认为去除骨皮质阻力后，牙齿与周围骨块形成整体在正畸力作用下加速移动，即为骨块移动理论。49精选ppt课件理论基础局部骨加速现象（regional acceleratory phenomenond RAP ）被认为是骨皮质切开术加速牙齿移动的根本原因，而不是骨块移动理论。50精选ppt课件理论基础局部骨加速现象（regional acceleratory phenomenond RAP ）为术后局部骨质产
