Dental CAD-CAM systems have advantages that cannot be matched with respect to the strength of materials and precision of the restorations. Dental materials used here are manufactured using standardized manufacturing procedures under strict quality control. These materials are generally better in quality, strength, and durability than those used to make dental restorations in the traditional casting process. Furthermore, due to the computer-controlled milling process, the materials are not subjected to human error that can lead to problems. Therefore, dental restorations fabricated from CAD-CAM systems possess optimum strength (all-ceramic materials have a flexural strength > 500 MPa). In terms of restorations precision, because of the accuracy of the scanner, software, and milling machine in a CAD-CAM system, the fit of the dental restorations is quite predictable.
