CAD/CAM Technology Challenges in Prosthodontics

Computer-Aided-Design/Computer-Aided-Manufacture or in short CAD/CAM technology is a revolutionary method which was utilized in dentistry in order to achieve more efficient and precise work that not only reduce time but also produce more patient satisfaction on the short and long term. Computer-Aided-Design (CAD) can be done by utilizing a specially designed software and an intraoral scanners or laboratory scanners which can construct a three dimensional image of scanned mouth or impression. Computer-Aided-Manufacture (CAM) on the other hand, can be done by subtractive or additive manufacturing. Subtractive manufacturing is done either by spark erosion or by a milling machine. Additive manufacturing on the other hand is made by layering technique in a step by step vertical buildup of the object or restoration. This review illustrates the indications, advantages, and limitations of CAD/CAM technology in construction of different types of restorations and the possible future of this technology.
