Abstract
For now, CAD / CAM technology has been introduced rapidly even in the dental field. Some have advanced to the introduction of prosthetic crown insurance. Particularly in implant implantation, 3D position of implantation is determined on CT data (CAD), surgical guide is designed by digital technology (CAD), and it is made by 3D printer or milling machine (CAM). Such a series of treatments can not be achieved without digital technology. Even in orthodontic field, digital setup will be a tool for making aligners so far, and future production planning of treatment plans and equipment for housing tooth in the alveolar bone based on the CT stereoscopic image will be full-fledged It will be coming and it is predicted that it will change drastically with the spread of intra oral scanner.
This time, I would like to make opportunities to organize and present each feature, advantage disadvantages etc. by comparing the production process of analog setup and digital setup so far.
