摘　　要：目的探讨年轻恒牙外伤性脱位再植成功率及其影响因素。方法选取2018年6月至2020年6月于本院治疗的76例(86颗牙)年轻恒牙外伤性脱位患者作为研究对象,对脱位的恒牙进行常规处理、植入并复位固定。比较植入成功与失败患者性别、离体时间、保存方法、根尖孔情况及牙周、牙槽损伤情况,采用Logistic回归模型分析影响患者再植成功率的影响因素。结果86颗脱位牙再植成功率为74.42%,有效率为16.28%,失败率为9.30%。离体时间≤1 h的成功率高于离体时间>1 h,脱位牙用湿保存方法的成功率显著高于用干方法保存,根尖孔状态为开放的成功率明显高于闭合状态,牙周、牙槽有损伤的成功率显著低于无损伤,差异有统计学意义(P<0.05);再植牙成功与未成功患者性别比较差异无统计学意义。Logistic回归分析结果显示,离体时间>1 h和干保存方法为影响再植成功率的危险因素(P<0.05)。结论脱位牙离体时间≤1 h、湿保存方法、根尖孔为开放状态、牙周与牙槽无损伤,有利于提高年轻恒牙外伤性脱位再植的成功率。Objective To explore the success rate and influencing factors of traumatic dislocation replantation in young permanent teeth.Methods A total of 76 patients(86 teeth)with traumatic dislocation of young permanent teeth treated in the hospital from June 2018 and June 2020 were enrolled as the research subjects,the dislocated permanent teeth were given routine treatment,implantation and reduction fixation.The gender,in vitro time,preservation methods,apical foramen,periodontal and alveolar injury in patients with implantation success and failure were compared,the influencing factors of replantation success rate were analyzed by Logistic regression model.Results In the 86 dislocated permanent teeth,success rate of replantation was 74.41%,the effective rate was 16.27%,and the failure rate was 9.30%.The success rate of in vitro time≤1 h was higher than that of in vitro time>1 h,the success rate of wet preservation method for dislocation teeth was significantly higher than that of dry preservation method,the success rate of open apical foramen state was significantly higher than that of closed state,the success rate of periodontal and alveolar damage was significantly lower than that of no damage,and the differences were statistically significant(P<0.05);there was no significant difference in gender between successful and unsuccessful replantation patients.The results of Logistic regression model analysis showed that in vitro time>1 h and dry preservation were risk factors affecting success rate of replantation(P<0.05).Conclusion In vitro time≤1 h,wet preservation,open apical foramen,periodontal and alveolar non-injury are beneficial to increase the success rate of traumatic dislocation replantation in young permanent teeth.
