title: Conservative preparation guidelines for CAD/CAM restorations.
abstract: The advent of computer-aided design/computer-aided manufacturing (CAD/CAM) technology has enabled clinicians to perform conservative dentistry more predictably. Rapid improvements in technology have spawned several computerized devices that can fabricate ceramic restorations within a matter of minutes. One such system, CEREC CAD/CAM, is designed to be used chairside, eliminating the need for conventional impression taking, temporary restorations, and multiple appointments. Prior to the arrival of CAD/CAM, the most commonly performed indirect restoration was the full-coverage crown with total axial reduction. Using CAD/CAM to scan and design allows dentists to keep preparations within enamel and, as a result, achieve an ideal bonded restoration that is conservative as well as innovative.
