摘　　要：目的评价数字化导板在即刻自体牙移植术中的初步应用效果。方法收集2022年10月—2023年10月于新疆医科大学第一附属医院口腔外科门诊就诊,且行自体牙移植术的患者54例,随机分为试验组和对照组,每组27例。对照组按照常规自体牙移植手术操作,试验组在对照组基础上应用数字化导板技术,分别记录两组手术时间(包括拔除患牙和供体牙时间、牙槽窝预备时间以及供体牙离体时间)、移植牙牙根愈合情况和临床疗效。结果试验组平均总手术时间、牙槽窝预备时间和供体牙离体时间分别为(23.77±4.32)、(6.54±1.77)和(2.80±0.57)min,均明显少于对照组(P<0.05);试验组颈部距离偏差、根尖部距离偏差、深度偏差和角度偏差小于对照组,差异具有统计学意义(P<0.05);两组牙根愈合情况和临床疗效比较无统计学差异(P>0.05);试验组3D模型牙试植次数明显少于对照组(P<0.05)。结论数字化导板能够有效减少即刻自体牙移植手术时间,精准预备受区牙槽窝并一次成功植入供牙,减少实际位置与术前设计的偏差距离。Objective To evaluate the preliminary application effects of digital guide plate in immediate autogenous tooth transplantation.Methods A total of 54 patients who attended the Department of Dental Surgery Clinic,the First Affiliated Hospital of Xinjiang Medical University for autotransplantation from October 2022 to October 2023 were collected,and randomly divided into the experimental group and the control group,with 27 cases in each group.In the control group,conventional autogenous tooth transplantation was carried out.In the experimental group,digital guide technology was added,and the operation time(including the time of extraction of the affected tooth and the donor tooth,the time of alveolar socket preparation,and the time of donor tooth in vitro),the healing of transplanted roots,and the clinical efficacy of transplanted teeth were recorded in the two groups,respectively.Results The average total surgical time,alveolar socket preparation time and the time of donor tooth in vitro of the test group were(23.77±4.32),(6.54±1.77)and(2.80±0.57)min,respectively,which were significantly less than those of the control group(P<0.05);the cervical distance deviation,apical distance deviation,depth deviation and angular deviation of the test group were smaller than those of the control group,and the difference was statistically significant(P<0.05);there was no statistical difference in root healing and clinical efficacy between the two groups(P>0.05);the number of trial implantation of 3D model teeth in the test group was significantly less than that in the control group(P<0.05).Conclusion The digital guide plate can effectively reduce the time for immediate autogenous tooth transplantation,accurately prepare the socket in the recipient area and successfully implant the donor tooth in a single pass,reducing the distance between the actual position and the preoperative design.
