摘　　要：目的:初步评价计算机动态导航在种植体植入的精准引导。方法:选择17例(25颗植体)患者纳入实验组,在动态导航系统引导下行种植体植入术;同时选取18例(25颗植体)已经在本科室行徒手种植体植入手术的患者作为对照组;分别测量术前规划虚拟种植体的植入点位置和角度及术后实际植入种植体的植入点位置和角度,算出偏差值进行比较。结果:实验组25枚种植体唇(颊)、舌(腭)向、近远中向平均偏差值分别为0.210 mm,0.318 mm,角度平均偏差值为3°,而对照组25枚植体唇(颊)、舌(腭)向、近远中向平均偏差值分别为0.339 mm,1.059 mm,角度平均偏差值为6.12°。实验组植入精准性明显优于对照组(P<0.001)。结论:动态导航系统能够显著的提高种植体植入的精准性,为修复创造最佳位置条件。Objective:To preliminarily evaluate the precision of guidance by computer dynamic navigation in dental implant placement.Methods:Seventeen patients(25 implants)were selected as the experimental group and implanted under the guidance of computer dynamic navigation.Eighteen patients(25 implants)who received freehand dental implant placement were selected as the control group.The entry position and angle of the planned implantation and actual implantation were measured,respectively.The deviation value was calculated for comparison.Results:The average deviation values of lingual(buccal)-tongue(palate)and proximal-distal directions in the experimental group were 0.210 mm and 0.318 mm,respectively,and average deviation of angle was 3°.The average deviation values in the control group were 0.339 mm and 1.059 mm,respectively,and average deviation of angle was 6.12°.The implantation accuracy of experimental group was better than that of control group(P<0.001).Conclusion:The dynamic navigation system can significantly improve the precision of dental implant placement.
