摘要：
The innovation is an integrated method of implant position planning and drilling guide generation for dental implant. The method is based on patient’s jaw models reconstructed from CT images and combines with his own dynamic occlusion surface. The optimal entry point of the implant can either be determined by patient’s occlusal surface or the moment of inertia of the jawbone in order to obtain a possible position of the implant automatically. The planning process takes into account several crucial lengths, in terms of safety distances, between the skull boundary, the nerve, and the implants, and could be fabricated by rapid prototyping machine. The design of the guide template solves the undercut interference when mount the guide plate on teeth, and also take into consideration mouth opening distance and clinical issues in order to build high precision and accuracy drill guide plate using in dental implant.本發明係一種植牙植體方位規劃暨植牙鑽孔導引板設計之整合方法,利用患者之電腦斷層影像重建出一顎骨影像模型並與患者之個人化動態咬合面結合,根據該動態咬合面可決定植牙植體之較佳進入點,或利用該顎骨影像模型其截面計算出適當之植體進入點與終點,待植體進入點及終點均確定後,可將之移轉至植牙鑽孔導引板之建立作業,並於設計該植牙鑽孔導引板考量干涉、開口度不足等問題,以建立高精確之植牙鑽孔導引板而應用於臨床手術。
