CT 기반의 치과용 CAD/CAM 기술 동향 및 적용 사례

As the quality of life improves, recently esthetic demands for dental treatments have been rapidly increased. New materials and remedies in dentistry have been developed to satisfy these trends. The CAD/CAM technology is an emerging technology to treat them well. The role of the CT system in the dental CAD/CAM systems is to obtain the 3D image of an object containing the complex shape in which a laser or a contact probe cannot reach. In general, the CT-based dental CAD/CAM systems provide dental engineers with the following sequential functions: to acquire the 3D image of an oral cavity, to convert the 3D image into a triangular-net based 3D model, to edit/modify the 3D model, and to manufacture various dental products. This study introduces CAD/CAM technologies applied in the dental fields such as implant surgery simulation, rapid prototype of guide stent and orthodontics and proposes the rapid manufacturing approach to make the zirconia copings.
