摘要： 目的: 评价计算机辅助设计下,3D打印技术应用于自体牙移植术的临床疗效分析。方法: 选取2016年5月~2019年5月31例患者,从年龄、性别、受区情况、供体牙发育情况、移植时间、模型制备时间、牙槽窝制备时间、供牙离体时间、供牙牙根与牙槽窝的平均距离、移植手术评分和移植牙成功率等角度进行分析。结果: 实验组和对照组牙槽窝预备时间为(12.28±3.15) vs (19.86±6.52) min,实验组和对照组供体牙离体时间分别为(3.22±1.21) vs (12.12±4.18) min,实验组和对照组牙根表面与受区牙槽窝的平均距离分别为(0.76±5.44) vs (1.31±0.16) mm。术后8周,实验组96.67%患者移植牙评分可达Ⅰ级和Ⅱ级,对照组为83.87%。术后6个月,实验组移植牙成功率为96.67%,存留率100%;对照组成功率为90.00%,存留率96.78%。结论: 依托计算机辅助设计联合3D打印技术,自体牙移植术可缩短供体牙离体时间、提升供区受区的匹配度,有效提高自体牙移植术的临床成功率。

Abstract: Objective: To evaluate the clinical effect of 3D printing technology in autogenous tooth transplantation. Methods: From May 2016 to May 2019, 31 patients were selected and analyzed from the perspectives of age, gender, receiving area, donor tooth development, transplantation time, model preparation time, alveolar fossa preparation time, donor tooth separation time, average distance between donor root and alveolar fossa, transplantation operation score, and success rate. Results: The preparation time of the experimental group and the control group was (12.28±3.15 vs 19.86±6.52) min, the separation time of the donor teeth in the experimental group and the control group was (3.22±1.21 vs 12.12±4.18) min, and the average distance between the root surface of the experimental group and the control group was (0.76±5.44 vs 1.31±0.16) mm, respectively. At 8 weeks after the operation, 96.67% of the patients in the experimental group achieved grade Ⅰ and grade Ⅱ , while 83.87% in the control group. Six months after the operation, the success rate of the experimental group was 96.67%, and the retention rate was 100%; the success rate of the control group was 90.00%, and the retention rate was 96.78%. Conclusion: Based on CAD and 3D printing technology, autogenous tooth transplantation can shorten the time of donor teeth in vitro, improve the matching degree of donor area and recipient area, and effectively improve the clinical success rate of autogenous tooth transplantation.
