摘　　要：目的:探讨中药骨碎补在减阻牵张快速牙齿移动过程中的作用机制。方法:实验对象为8只杂种犬,将口内4个后牙区随机分为常规方法侧、减阻牵张侧、常规方法加注射骨碎补侧及减阻牵张加注射骨碎补侧。实施相应措施后,在加力2周、停止加力1和4周时进行移动牙移动距离的测量,拍摄X线片。结果:①加力2周,常规侧、减阻牵张侧、常规加注射骨碎补侧和减阻牵张加注射骨碎补侧第一前磨牙向远中分别移动了0.81、3.71、1.38和3.67mm;常规法侧第一前磨牙平均移动距离与常规法加注射骨碎补侧比较差异有显著性(P<0.05);减阻牵张侧第一前磨牙平均移动距离与减阻牵张加注射骨碎补侧比较差异无显著性(P>0.05);②X片显示未见移动牙牙根明显吸收及骨质缺损;③减阻牵张加注射骨碎补侧移动牙的稳固早于减阻牵张侧。结论:常规方法加注射骨碎补可加快牙齿移动速度,减阻牵张后注射骨碎补不能进一步加速牙齿移动速度,但可以促进移动牙的稳固。Objective To investigate the effect of Gusuibu on the rapid tooth movement in dogs treated by resistance reduction and distraction osteogenesis.Methods A total of 8 local hybrid dogs were selected in this study.The second pre-molar extracted in both sides,four posterior regions in each dog were assigned as regular tooth movement（A）,rapid tooth movement（B）,regular tooth movement combined with Gusuibu injection（C）,rapid tooth movement combined with Gusuibu injection（D）.The distance of tooth movement,pulp test and radiography examination were performed for each side on the 2nd,3rd,6th week.Results The average distances of tooth movement on each side were 0.81（A）,3.71（B）,1.38（C）,and 3.67（D）mm,respectively.The distance of tooth movement in side C was significantly bigger than that in side A（P〈0.05）,and there was no significant difference between sides B and D.By means of X-ray examination,no significant apical root resorption was detected in each side.The stability of moving tooth in side D occurred early than side B.Conclusion During the regular tooth movement,Gusuibu could increase the speed of tooth movement.However,during rapid tooth movement,Gusuibu could not increase the speed of tooth movement,but increase the stability of moving teeth.
