OBJECTIVES: To assess the accuracy of implant placement in models and satisfaction in dynamic navigation assisted postgraduate dental students training. METHODS: Postgraduate dental students who had at least one year of dental clinical practice with no experience in dental implant surgeries were included. Students were instructed to make treatment plans in the dynamic navigation system. Each student placed two maxillary right incisors, using freehand approach at first and then under dynamic navigation. The implant position was compared with treatment plan. Factors influencing the accuracy of implants placed under dynamic navigation were analyzed. Student acceptance towards the training and use of dynamic navigation was recorded using a questionnaire. RESULTS: A total of 21 students placed 42 implants. For freehand implant placement, the median entry point deviation, apex point deviation, and implant axis deviation was 3.79 mm, 4.32 mm, and 10.08°. For dynamic guided implant placement, the median entry point deviation, apex point deviation, and implant axis deviation was 1.29 mm, 1.25 mm, and 4.89° (p < 0.001). The accuracy of dynamic guided implant was not influenced by student gender or familiarity with computer games. All students were satisfied with the training. CONCLUSIONS: Dynamic navigation system assisted students in improving the accuracy of implant placement and was well accepted by students.
目的：评估模型中种植体放置的准确性和动态导航辅助研究生牙科学员培训的满意度。
方法：纳入至少有一年牙科临床实践经验但无牙科种植手术经验的研究生牙科学员。学生被指导在动态导航系统中制定治疗计划。每位学生首先采用徒手方法，然后在动态导航下放置两颗上颌右切牙。将种植体位置与治疗计划进行比较。分析影响动态导航下种植体准确性的因素。使用问卷记录学生对培训和动态导航使用的接受程度。
结果：共有 21 名学生放置了 42 颗种植体。对于徒手种植体放置，中位入口点偏差、顶点偏差和种植体轴偏差分别为 3.79mm、4.32mm 和 10.08°。对于动态引导种植体放置，中位入口点偏差、顶点偏差和种植体轴偏差分别为 1.29mm、1.25mm 和 4.89°（p<0.001）。学生的性别或对电脑游戏的熟悉程度并不影响动态引导种植体的准确性。所有学生均对培训感到满意。
结论：动态导航系统有助于学生提高种植体放置的准确性，并得到学生的认可。
