摘　　要：目的:探讨三维打印导板在残冠残根根管治疗中的应用疗效。方法:选取72例残冠残根患者作为研究对象,随机分为两组。导板组三维打印导板重建残冠残根冠方平面,确定参照点;对照组在残冠残根剩余牙体边缘或邻牙边缘找寻参照点,两组均采用Protaper Gold器械预备结合热牙胶垂直加压充填。对两组各项指标及疗效进行分析。结果:导板组患者主尖就位率、恰充率、成功率、充填精确性均优于对照组,且平均治疗时间也短于对照组,差异均具有统计学意义(P<0.05);同时导板组患者前磨牙与磨牙的精确性差异无统计学意义(P>0.05),而对照组患者前磨牙与磨牙的精确性差异有统计学意义(P<0.05)。结论:残冠残根根管治疗中采用三维打印导板恢复冠方参照点,能有效减小根管治疗误差,提高治疗效率和成功率,增加患牙远期留存率。Objective:To evaluate the effect of three-dimensional printed template in root canal therapy of residual crown and root.Methods:A total of 72 patients with residual crown and root were randomly divided into two groups.In the template group,the template was three-dimensional printed to reconstruct the square plane of the residual crown and root,and the reference point was determined.In the control group,the reference point was found on the residual crown and root of the tooth or adjacent tooth edge,and both groups were treated with Protaper Gold instrument preparation combined with hot dental glue vertical compression filling.The main gutta percha point positioning rate,filling rate,success rate and filling accuracy of the template group were better than those of the control group,and the average treatment time was also lower than that of the control group.There were significant differences between the two groups(P<0.05).There was no significant difference in the accuracy between premolars and molars in the guide group(P>0.05),but there was significant difference between premolars and molars in the control group(P<0.05).Conclusion:The use of three-dimensional printed template to restore the reference point of crown prescription in root canal treatment can effectively reduce the error of root canal treatment,improve the efficiency and success rate of treatment,and increase the long-term retention rate of affected teeth.
