摘　　要：目的:探讨正畸加载时机和持续时间对自体移植牙牙周修复预后的影响。方法:选择12只比格犬,随机分为4组,每组3只,每犬选择4颗第1前磨牙进行自体移植,分别于自体牙移植手术后的第2、4、8、12周进行正畸加载,持续时间分别为1、2、4周,对其第1前磨牙牙周组织进行研究,检测牙根吸收率,分析其牙周组织的恢复情况。结果:实验组正畸加载自体移植牙牙根吸收率明显低于对照组无正畸加载自体移植牙牙根吸收率,差异显著,具统计学意义,不同加载时机与持续时间对自体移植牙牙根吸收率的影响无明显差异,不具统计学意义,但此2个因素存在交互作用。结论:正畸力加载能够有效改善自体移植牙牙根吸收状况和牙周组织,但正畸加载时间和持续时间对自体移植牙吸收率的影响不够明显,自体牙移植4周后进行正畸加载,持续2周对改善自体移植牙牙周组织具有最为明显的效果。Objective：To investigate the orthodontic loading the timing and duration of the prognosis of the autologous transplant periodontal repair. Methods： 12 beagle dogs were randomly divided into four groups （ n = 3 ） , each dog choose four first premolars autologous transplantation , respectively, in the autogenous teeth transplantation 2,4,8 and 12 weeks after the surgery the orthodontic load duration of 4 weeks, their first premolar periodontal tissue research , detection of root resorption rate analysis of periodontal tissue recovery . Results： the experimental group the orthodontic loaded autologous transplantation tooth root absorption rate significantly lower than the control group without orthodontic loaded autologous transplantation tooth root absorption rate, the difference was significant , statistically significant , the different loading timing and duration of autologous transplantation tooth root absorption rate was no significant difference not statistically significant , but two factor interaction . Conclusion： The orthodontic force loading can effectively improve the autologous transplant tooth root absorption status and periodontal tissue, but the orthodontic load time and duration of the impact on theautologous transplantation teeth absorption rate is not obvious enough ,Most obvious effect for two weeks on improving autologous transplantation periodontal tissue to orthodontic loading from extracted teeth 4 weeks after transplantation .
