The smile design (CAD-CAM) is the application of computer technology for the design and manufacture of dentures. The computer controlled dental treatments are also used for diagnosis and implant surgery, making minimally invasive. Using software, the dentist can plan and create dental splints as with better materials. Furthermore, the design of the CAD-CAM smile helps reduce production costs, reduce manufacturing time crowns, veneers or bridges and the number of office visits. The CAD-CAM system consists of three phases: data digitization or scanning of the part to restore computer graphics of the structure of the prosthesis (CAD) and manufacturing by a robot of the same (CAM). In the field of surgery, the technology allows for better planning, simulating the operation and provide the results of the intervention before testing.
