摘　　要：目的:利用口内光学扫描技术评价导板种植精度并探讨其影响因素。方法:选择符合纳入标准的牙列缺损患者27例,进行回顾性研究。利用3Shape Implant Studio软件设计种植方案并生成相应的数字化导板,临床进行引导种植手术。使用3Shape TRIOS口内扫描仪获取术后牙列数字化模型,在Geomagic软件中逆向构建植体位置,结合术前方案中设计位点,评价种植体偏移情况。采用SAS 9.4软件包进行数据分析。结果:以光学扫描方法得到数字化导板精度为植入点偏差(1.182±0.609)mm,根尖点偏差(1.658±0.741)mm,角度偏差(5.712±3.347)°。种植导板的距离偏移可能受工作象限、缺牙位点、引导程度、黏膜辅助支持、种植体尺寸等临床因素影响,而角度偏移主要受引导程度和缺牙数量影响。结论:数字化导板的临床效果受到诸多因素影响,提高数字化导板种植精度需要更多研究数据支持。PURPOSE:To evaluate the accuracy of static guided implant placement with intraoral scanning technology and to analyze the influencing factors of guided surgery.METHODS:Totally 27 cases were included in this retrospective study.The implant designs were made in 3Shape Implant Studio and then guided implant surgeries were performed with CAD-CAM templates.Postoperative implant positions were detected with an intraoral scanner(3Shape TRIOS)and deviation of implantation was evaluated using established CAD/CAM based evaluation method.SAS 9.4 software package was used for data analysis.RESULTS:The mean deviation of entrance point and apical point was(1.182±0.609)mm and(1.658±0.741)mm,respectively.Angular deviation was(5.712±3.347)°.Implant quadrant,location of the implant site,guidance degree,supporting type and implant size influenced direction deviation,while angular deviation was mainly affected by guidance degree and number of missing teeth.CONCLUSIONS:Accuracy of static guided implant placement can be influenced by many factors.More research is needed to improve the accuracy of static guided implantation.
