A model of the product is fabricated by the CAD based on these inputs. This data set is different for each type of CAD/CAM application. The data obtained from scanning is then transferred to CAD. Various surface digitization techniques like Laser Scanning, Ultrasound, Magnetic Resonance Imaging, Computed Tomography, Contact Profilometry is employed CAD This is done by a ruby ball and then the three-dimensional data is obtained. In this method, the master cast is read mechanically. They collect three-dimensional data using a process called “triangulation.” Mechanical Scanners And then it transforms them into digital data sets. It measures three-dimensional jaw and tooth structures. CAM Computerized Surface Digitization Using ScannersĪ scanner in dentistry is essentially a data collection device.Computerized Surface Digitization Using Scanners.2 – Design of Tooth using CAD/CAM Software Architecture of CAD/CAM System in DentistryĬAD/CAM system is usually made of three main components: He demonstrated his system at the French Dental Association’s International Congress in November 1985 and from then on, this system has grown leaps and bounds.įig. He delivered the first dental CAD/CAM restoration in 1983. The optical impression of the abutment tooth was taken and then it was produced using a numerically controlled Milling machine. He was making crowns based on an optical impression. Duret was the first dentist to develop a dental CAD/CAM device. Werner Mormon of Switzerland, Dr.Dianne Rekow of the United States, and Matts Andersson of Sweden. The most important names in dental CAD/CAM development are Dr. This technology was initially used in the aircraft and automotive industries during the 1960s. 1 – Introduction to CAD/CAM Technology in DentistryĬAD/CAM was used for the first time in dentistry after a decade of its invention. CAD is used in the design and construction of veneers, implant abutments, crowns, inlays, onlays, fixed partial dentures, full-mouth reconstruction, and orthodontics while CAM is used in the manufacturing of the designed unit.įig. In dentistry, it is a system that is used to improve the design and fabrication of dental restorations. Is AutoCAD useful for Engineers? What is CAD/CAM Technology in DentistryĬAD/CAM is the short form of Computer Aided Designing and Computer Aided Manufacturing.
