CAD-CAM is the acronym for computer-aided design and computer-aided manufacturing, it offers high precision and high quality restorations. The whole process involves 3D designing and imaging of the teeth using computer software. Once the restoration is designed by the computer under the direction of a dentist, the information is sent to a sculpting machine which creates the restoration to exact specification. The precision and fit of such crowns are much superior to manually built-up crowns.
