摘　　要：目的:通过对比动态导航引导下颌骨不同部位的种植体植入精度,分析种植部位解剖条件和局部骨质等因素对手术偏差的影响。方法:依照种植位点在牙弓中的位置分为上颌前部、上颌后部、下颌前部、下颌后部4组,分析患者种植体的植入点偏差、角度偏差和末端点偏差。运用SPSS 24.0软件,采用t检验对上下颌拟种植区以及相同牙弓前后部的3个指标进行统计分析。结果:在植入点偏差的指标上,仅上下颌前部之间存在显著性差异(P<0.05);同颌牙弓前后部在末端点偏差和植体角度偏差均有显著统计学差异(P<0.05),上下颌在牙弓后部有显著性差异(P<0.05)。结论:动态导航引导下牙种植术因颌骨不同部位的解剖条件和骨质状况差异种植精度有所不同,总体上,上颌前部的种植精度高于下颌前部,下颌后部的种植精度高于上颌后部,同颌前部种植精度高于后部。Objective: To analyze the influence of different areas on dynamic navigation by comparing the implant placement accuracy. Methods: According to the position of implant site, the patients were divided into four groups: anterior maxillary, posterior maxillary, anterior mandibular, and posterior mandibular. The implantation point deviation, angle deviation, and end point deviation of implants were analyzed. Results: Concerning the implant point deviation, there was significant difference in the anterior parts between upper and lower jaws(P<0.05). Concerning the angle deviation and end point deviation of implants, there were significant differences between anterior and posterior parts(P<0.05), and at the rear of the dental arch between upper and lower jaws(P<0.05). Conclusion: The accuracy of dynamic navigation-guided dental implantation varies according to the anatomical conditions and bone conditions of different parts of the jaw.
