The hybrid navigation technique involves the merging of the Dynamic navigation (DN) system (Navident, Claronav, Canada) and static navigation technique (3Shape, Copenhagen, Denmark). Combining the advantages of both techniques, devising a protocol of hybrid navigation will be advantageous to eliminate the difficulties faced by operators in using either methods separately. Three patients requiring dental implants were included in this study. This requires the cone beam computed tomography (CBCT) (Digital Imaging and Communications in Medicine (DICOM) data) and intra-oral scan (Standard Tessellation Language (STL) format) data for the accurate planning of the implant positions in both the static and dynamic approaches. The steps carried out were repeated for each of the patients, the accuracy of the implant placement was verified postoperatively by merging the CBCT data pre and post through the Evalunav software (NaviDent, Claronav). The accuracy of the implants placed were assessed based on the mesio-distal, bucco-lingual, apical deviations in distance and in angulation. The semi-robotic DN and static guide combination as a hybrid technique is an interesting method to improve the accuracy of flapless implant surgeries and can be used in cases where the anatomical landmarks are determinant factors for the implant placement.
混合导航技术涉及动态导航（DN）系统（加拿大Claronav公司的Navident）与静态导航技术（丹麦哥本哈根3Shape公司的产品）的融合。结合两种技术的优点，设计一种混合导航方案将有利于消除操作人员单独使用任何一种方法时所面临的困难。本研究纳入了三名需要种植牙的患者。这需要锥形束计算机断层扫描（CBCT）（医学数字成像和通信（DICOM）数据）和口腔内扫描（标准细分语言（STL）格式）数据，以便在静态和动态方法中准确规划种植体位置。对每位患者都重复进行所执行的步骤，术后通过Evalunav软件（加拿大Claronav公司的NaviDent）合并术前和术后的CBCT数据来验证种植体植入的准确性。根据近远中、颊舌向、根尖方向的距离偏差和角度偏差来评估种植体植入的准确性。半机器人DN与静态导板相结合作为一种混合技术，是提高无瓣种植手术准确性的一种有趣方法，可用于解剖标志是种植体植入决定因素的病例。
