摘要
目的探讨3D打印辅助自体牙移植修复牙齿缺失的临床疗效评价。方法选取自2017年9月-2021年8月在西安交通大学附属口腔医院口腔外科门诊行自体牙移植手术病例169例,移植牙176颗,分别从年龄、性别和受牙牙位、受牙患病或缺失情况、供体牙牙位及手术时长、随访情况等方面进行分析。结果共完成牙移植手术169例,移植牙176颗,其中传统牙移植133例,3D打印辅助自体牙移植43例。3D打印辅助牙移植手术的供体牙离体时间比传统牙移植显著缩短(P<0.0001)。术后3个月因牙齿松动无法保留而拔除者(认定为移植失败)共9颗,其中传统牙移植失败7例,3D打印辅助自体牙移植失败2例。传统牙移植手术成功率为77%,存留率为94.7%;3D打印辅助牙移植手术成功率为88%,存留率为95.3%。结论应用3D打印供牙模型完成自体牙移植手术显著缩短供体牙离体时间,减轻对移植牙牙周膜细胞的损伤,可提高牙移植成功率,值得推广。
Objective To evaluate the clinical effect of 3D printing technology in autogenous tooth transplantation for tooth loss.Methods From September 2017 to August 2021,169 patients(176 teeth)were selected and analyzed regarding age,gender,recipient site,positioning of the donor tooth,transplantation time,and long-term follow-up.Results A total of 176 autogenous tooth transplants were completed,consisting of 133 cases of traditional autogenous tooth transplantation and 43 cases of autogenous tooth transplantation with 3D printing technology.The donor tooth separation time for autogenous tooth transplantation with 3D printing technology was significantly less than that for traditional autogenous tooth transplantation(P<0.0001).A total of nine teeth were removed 3 months after the operation due to loosening(autogenous tooth transplantation failure),among which seven failed in traditional tooth transplantation and two failed in autologous tooth transplantation with 3D printing technology.The success rate of traditional tooth transplantation was 77%and the retention rate was 94.7%.The success rate of tooth transplantation with 3D printing technology was 88%,and the retention rate was 95.3%.Conclusion 3D printed tooth donor model can greatly shorten the time of tooth donor,reduce the damage to the periodontal membrane cells of the transplanted teeth,and improve the success rate of tooth transplantation.It is worthy of broad promotion.
