15、出骨皮质切开加速牙齿移动这一概念。l1959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。l2001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。加快正畸牙齿移动的方法49理论基础理论基础l骨块移动理论（bone 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

16、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。加快正畸牙齿移动的方法50理论基础理论基础l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。加快正畸牙齿移动的方法51理论基础理论基础l局部骨加速现象（regional acceleratory phenomenond RAP）为术后局部骨质产生的暂时性脱矿与再矿化l表现为:在骨组织创伤后术创附近的牙槽骨进入短暂可逆的骨质减少状态，骨吸收

17、及溶骨现象随即出现;在这一分解代谢的过程中骨密度虽然降低，但牙槽骨骨量并没有减少;正畸力施加使得牙根周围骨基质及骨胶原软组织基质随之移动;在随后的再矿化过程中新骨沉积，类骨质基质再矿化，重新包绕牙根周围。加快正畸牙齿移动的方法52l骨皮质切开术后一段时间可以加快正畸牙齿移动的速度，而该过程是基于引发现象后牙槽骨吸收和重建过程（RAP）.加快正畸牙齿移动的方法53临床应用临床应用l解除拥挤l矫正上前牙唇倾，加速前牙内收，改善前突面型l骨性 三类错合畸形下前牙舌倾的去代偿l个别牙齿的错合畸形也有很好的疗效，压低伸长磨，牵引埋伏牙，根骨黏粘牙齿l解除后牙反牙合加快正畸牙齿移动的方法54 Lower
