Abstract：
BACKGROUND: The operation accuracy and efficiency of dynamic navigated endodontic surgery were evaluated through in vitro experiments. This study provides a reference for future clinical application of dynamic navigation systems in endodontic surgery.
METHODS: 3D-printed maxillary anterior teeth were used in the preparation of models for endodontic surgery. Endodontic surgery was performed with and without dynamic navigation by an operator who was proficient in dynamic navigation technology but had no experience in endodontic surgery. Optical scanning data were applied to evaluate the length and angle deviations of root-end resection. And the operation time was recorded. T tests were used to analyze the effect of dynamic navigation technology on the accuracy and duration of endodontic surgery.
RESULTS: With dynamic navigation, the root-end resection length deviation was 0.46 ± 0.06 mm, the angle deviation was 2.45 ± 0.96°, and the operation time was 187 ± 22.97 s. Without dynamic navigation, the root-end resection length deviation was 1.20 ± 0.92 mm, the angle deviation was 16.20 ± 9.59°, and the operation time was 247 ± 61.47 s. Less deviation was achieved and less operation time was spent with than without dynamic navigation (P < 0.01).
CONCLUSIONS: The application of a dynamic navigation system in endodontic surgery can improve the accuracy and efficiency significantly for operators without surgical experience and reduce the operation time.

摘要：
背景：通过体外实验评估了动态导航牙髓手术的操作准确性和效率。本研究为动态导航系统在牙髓外科的临床应用提供了参考。
方法：使用3D打印的上颌前牙制备牙髓手术模型。牙髓手术是由精通动态导航技术但没有牙髓手术经验的操作员在有或没有动态导航的情况下进行的。应用光学扫描数据评估根端切除的长度和角度偏差。并记录手术时间。采用T检验分析动态导航技术对牙髓手术准确性和手术时间的影响。
结果：使用动态导航，根端切除长度偏差为0.46±0.06mm，角度偏差为2.45±0.96°,手术时间为187±22.97s。没有动态导航，根端切除长度偏差为1.20±0.92mm，角度偏差为16.20±9.59°,手术时间为247±61.47s。与不使用动态导航相比，获得的偏差更少，花费的手术时间更少（P<0.01）。
结论：在牙髓手术中应用动态导航系统可显著提高无手术经验的手术者的准确性和效率，缩短手术时间。
