摘　　要：目的:探讨牙根发育完成自体牙移植远期预后及影响因素,为后续临床治疗提供参考。方法:回顾性分析我院2008年1月~2015年1月收治牙根发育完成自体牙移植患者共64例72颗临床资料,于术后随访复查相关临床资料及根尖X线片,根据年龄、性别及接受根管治疗与否分析临床预后相关影响因素,采用Kaplan-Meier法和Log-rank法评估移植牙的5年累积存活率和成功率。结果:72颗自体移植牙随访5年累积存活率和累积成功率分别为83%和65%;<27岁和≥27岁组自体牙移植累积存活率、累积成功率比较差异均无统计学意义(P>0.05);男性和女性亚组自体牙移植累积存活率、累积成功率比较差异均无统计学意义(P>0.05);接受与未接受根管治疗组自体牙移植累积存活率比较差异均无统计学意义(P>0.05);接受根管治疗组自体牙移植累积成功率显著高于未接受根管治疗组(P<0.05)。结论:牙根发育完成自体牙移植临床预后良好,可作为牙齿缺失修复重要候选方案;同时术后完善根管治疗有助于提高患者远期牙移植成功率。Objective:To investigate the long-term prognosis and influencing factors of autologous tooth transplantation after root development.Methods:64 patients and 72 teeth with autologous tooth transplantation after root development were retrospectively chosen from January 2008 to January 2015 and the related clinical data and apical X-ray film were reviewed after operation.The influencing factors of clinical prognosis were analyzed according to age,sex,and root canal therapy experience.The 5-year cumulative survival rate and success rate of transplanted teeth were evaluated by Kaplan-Meier method and Log-Rank method.Results:The 5-year cumulative survival rate and cumulative success rate of 72 teeth with autologous transplanted teeth were respectively 83%and 65%.There was no significant difference in the cumulative survival rate and success rate between patients with age<27 years old and≥27 years old(P>0.05).There was no significant difference in the cumulative survival rate and success rate between patients gender(P>0.05).There was no significant difference in the cumulative survival rate between patients with or without root canal therapy(P>0.05).However,the success rate of patients with root canal therapy were significant higher than patients without root canal therapy(P<0.05).Conclusion:Autogenous tooth transplantation after root development possess good clinical prognosis and can be used as the important candidate for the restoration of missing teeth.Improving root canal therapy after operation is helpful to higher the long-term success rate of tooth transplantation.
