This document summarizes the history and development of CAD/CAM technology in dentistry. It discusses early systems from the 1950s and key developments in the 1970s and 1980s. It then outlines the CAD/CAM process, including digital impression taking, design of restorations, milling, and cementing the final restoration. The document reviews materials used including ceramics, resins, and metals. It also discusses advantages like eliminating errors and the need for temporaries or second visits. Finally, it provides a brief overview of common contemporary CAD/CAM systems and their applications in dentistry.

are changing across the board, and
the dental industry is no exception. The
catalyst for change in this industry have been
the digital platforms that have been
developed, working in concert with the
economic situation we find ourselves in
today”

1985 Dr. Moermann- CEREC® system (inlay)
1980s Dr. Andersson- Procera® system
(titanium copings and composite veneered
restorations)
This system later developed as a processing center
networked with satellite digitizers around the world for
the fabrication of all-ceramic frameworks. [2]

called digitizers and scanners, to obtain
digital data that represents morphology of
target tooth.
