动态实时导航与数字化导板导航牙种植精确度的比较

Research on the accuracy of dynamic real⁃time navigation and digital guide navigation implanting techniques

目的比较采用动态实时导航与数字化导板导航牙种植术植入种植体的精确度,为临床实施精准牙种植提供参考。方法选择2018年4月到2019年12月梧州市红十字会医院口腔科收治的46例(70颗牙)牙缺失患者,随机分两组(每组35颗牙)分别行动态实时导航和数字化导板导航牙种植术,比较两组种植体术前设计位置和术后实际种植位置的颈部、尖部、深度和角度偏差。运用SPSS 21.0软件对数据进行统计学分析。结果两组患者种植手术均顺利进行并完成种植体的成功植入。动态实时导航组种植体尖部、深度和角度的偏差均小于数字化导板导航组的偏差,差异具有统计学意义(P<0.05),动态实时导航组和数字化导板导航组在颈部中心点的偏差无统计学意义(P>0.05)。结论动态实时导航与数字化导板导航种植手术均有较好的临床效果,前者的精度高于后者。

Objective To compare the accuracies of implants with dynamic real⁃time navigation versus digital guide navigation to provide a reference for clinical precision dental implants.Methods Forty⁃six cases(seventy teeth)with missing teeth admitted to the Department of Stomatology,Wuzhou Red Cross Hospital from April 2018 to Decem⁃ber 2019 were randomly divided into two groups(thirty⁃five teeth in each group)for dynamic real⁃time navigation and digital guide navigation implantation techniques.To compare the entry point,apex point,depth and angle deviation of the preoperative and postoperative position of implants in the two groups.SPSS 21.0 software was used for statistical analysis.Results Dental implants were successfully placed in both groups.The deviations of apex point,depth and an⁃gle in the dynamic real⁃time navigation group were all smaller than those in the digital guide navigation group,and the differences were statistically significant(P<0.05).There was no statistically significant deviation in the entry point be⁃tween the two groups(P>0.05).Conclusion In this study,both techniques had good clinical effects.The accuracy of dynamic real⁃time navigation was higher than that of digital guidance。
