Abstract: Through 3-dimension (3D) Computed Tomography (CT) images, a virtual stomatological implantation orientation Computer-Assisted Design (CAD) navigation system is proposed in this study. The system reconstructs the 3D images and the multi-plane image of the teeth with the combination of spiral X-CT, computer graph and image and 3D visualization. The height, width, shape of the (alveolar bone) of jaw bone, the accurate position of lost teeth and mentum aperture, the density of ossicles, the orientation of submaxillary, the position and shape about the bottom of nasal cavity and antrum maxillary can be got.The maxillary evaluation in terms of radiography before the tooth implantation and the guidance about the clinic localization of false tooth can be provided in the system, in which the doctor can not only greatly reduce the risk of implantation operation but also improve the stability and security of tooth implantation.
