The first computer-aided design and computer-aided manufacturing (CAD-CAM) machine was created in the 1960s for building parts of an automobile. In dentistry, CAD-CAM milling has been in use since 20 years. Still, CAD-CAM’s limitations seem to be keeping the technology from becoming status quo in the general dentist’s office.
CAD covers 2D drawings, 3D models of parts, assemblies and even gigantic projects. Fit and function testing is possible once we have the CAD data of whatever is being designed. A CAD model can also be considered as a virtual prototype. There are many manufacturing processes and there are many machines for each type of manufacturing process (CAM). Computers have been integrated into those machines and they are called CNC (Computer Numerically Controlled) machines. Most of these work by subtracting the material from a raw block. For example, CNC turning centers and machining centers (Milling + Drilling with Automatic Tool Changers). These CNC machines require certain computer codes for operating. These are called CAM codes or programs.
