摘要/Abstract

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。

Abstract: 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.
