Description

technical field

[0001] The invention relates to a three-dimensional dental prosthesis external grinding and repairing simulation test machine, which belongs to the external grinding and repairing device for prosthetics in the field of dental prosthesis. Background technique

[0002] Since the application of CAD / CAM technology in the field of prosthodontics in the 1970s, the computer-aided design and manufacturing technology of dentures has developed rapidly. At present, more than 10 related products have been sold in the market abroad. In recent years, some domestic scholars have begun to pay attention to CAD / CAM technology for oral restoration. Researchers such as Lu Peijun of Peking University Stomatological Hospital have initially developed my country's first independent intellectual property rights for oral restorations (crowns, bridges, inlays, etc.) Computer-aided design and manufacturing experiment system [1-2]. Tianjin University and the School of Stomatology of Tian...
