Establishment of the database of standard crown
Standard crown database is an important part of CAD packages for a complete denture CAD/CAM system. Standard crown model is the geometrical model base of standard teeth database. In this study, based on the standard model of dental resin, the surface model of crown was created by using reverse engineering technology and denture feature modeling technology. These technologies meet the CAD/CAM system requirements. The process includes data acquisition, data processing and model reconstruction, and then a CAD model was generated. In this paper, the standard crown CAD model of Asians 28 permanent teeth was developed, based on this model E-R model of standard crown database was created, it provides model basis for developing denture CAD/CAM system with China's own intellectual property.
