This technique report describes a fully digital workflow in which two surgical guides (i.e. one for alveolar bone reduction and the other for implant placement) are magnetically connected to ensure stability during full-arch implant surgery following guided bone reduction. Digital prosthesis design as well as virtual bone reduction and implant planning are developed from the superimposition of facial, intraoral and CBCT scans. With this technique, different surgical guides and interim poly(methylmethacrylate) (PMMA) fixed prosthesis are precisely connected with magnets after being digitally designed and 3D-printed. As a result, such magnetic connection allows for satisfactory stability of the implant surgical guide, as well as of the interim fixed PMMA fixed prosthesis during capture of screw-retained abutments.
本技术报告描述了一种完全数字化的工作流程，其中两个手术导板（即一个用于牙槽骨减少，另一个用于种植体放置）通过磁性连接，以确保在引导骨减少后的全口种植手术中保持稳定。数字义齿设计以及虚拟骨减少和种植体规划是通过面部、口内和 CBCT 扫描的叠加来开发的。使用这种技术，不同的手术导板和临时聚甲基丙烯酸甲酯（PMMA）固定义齿在经过数字化设计和 3D 打印后，通过磁铁精确连接。因此，这种磁性连接允许种植体手术导板以及临时固定 PMMA 固定义齿在固定螺丝保留基台时具有令人满意的稳定性。
