摘要
目的：评估口内扫描技术静态引导种植体植入的准确性，并分析引导手术的影响因素：本次回顾性研究共纳入 27 个病例。种植体设计在 3Shape Implant Studio 中完成，然后使用 CAD-CAM 模板进行引导种植手术。术后使用口内扫描仪（3Shape TRIOS）检测种植体位置，并使用已建立的基于 CAD/CAM 的评估方法对种植体偏差进行评估。数据分析使用 SAS 9.4 软件包：结果：入口点和根尖点的平均偏差分别为（1.182±0.609）毫米和（1.658±0.741）毫米。角度偏差为（5.712±3.347）°。种植体象限、种植部位的位置、引导程度、支持类型和种植体大小对方向偏差有影响，而角度偏差主要受引导程度和缺失牙数量的影响：结论：静态引导种植体植入的准确性会受到很多因素的影响。结论：静态引导种植体植入的准确性会受到很多因素的影响，需要进行更多的研究来提高静态引导种植体植入的准确性。
[Accuracy evaluation of static guided implant placement using an intraoral scan method].
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.
