Research on digitalized design technology of teeth shape support implant guide based on image guide

摘要

This paper proposed a novel method for dental implant guide, based on computer aided design technique with CT data and dental 3D data. We analyze the patient's 3D dental data, and then plan the implant area and support area interactively. With the help of 2D image, we can accurately calculate the anatomical implants direction and a safe distance. With biomechanical principles as well as aesthetical and functional requirements as precondition, this method can make full use of the remaining teeth to ensure the support's stability. First of all, this method needs import and preprocess the model which needs repairing. Secondly, the implant direction was automatically computed. After that, the implant and support area was designed semi-automatically. Then, we design the dental platform and implant parametrically with the help of CT image registration. Finally, the dental implant guide is generated after Boolean operations. In the end of this paper, a case research explained the whole process of surgical guide. The results validated the correctness and feasibility of this method which has a great significance to enhance the quality and accuracy of implant surgery.
