Dental restorations fabricated using the dental precision casting system are applied to daily dental practice. This will contribute to maintain and control patients' oral functions. These dental laboratory activities to fabricate dental restorations have changed from the former wax-up method performed by hand to use of the CAD/CAM machinery processing system. This will promote the simplicity of the fabricating process and improve the laboratory environment. The use of this technology will expand the dental CAD/CAM system and contribute to the advancement of dental medicine.
