A simple definition of CAD/CAM dentistry is the use of digital software to design and manufacture dental restorations and prostheses. CAD stands for computer-aided design and CAM stands for computer-aided manufacturing. The technology can be used to create crowns, dentures, inlays, onlays, bridges and veneers among other things. The speed of the CAD/CAM process allows for dental prosthetics to be designed, manufactured and delivered to the patient in quick time, sometimes the same day. The wider system of using computer assisted technologies to produce restorations is known as CEREC (Chairside Economical Restoration of Aesthetic Ceramics).
