    Author: Lü P, Li Y, Wang Y, Zou B, Zhao J, Zhang Z.
    Journal: Zhonghua Kou Qiang Yi Xue Za Zhi; 2002 Sep; 37(5):367-70; discussion 370. PubMed ID: 12425852.
    Abstract:
    OBJECTIVE: To develop a dental CAD/CAM system with the autonomic intellectual property. METHOD: 28 standard teeth crowns were scanned using a newly 3-D laser scanner. As a development platform the Matlab 5.3 were used to process the acquired data, also be used to define the characterized areas on the surfaces of the crowns and to change the crowns form. The software of Surfacer 10.5 to develop a new CAD software for fixed prosthetics, and the 3.5 axis numerical controlled machine to manufacture the prosthetics were used. RESULT: It is the first time, the 3D graphic data bank of Chinese teeth crowns with a standard form was established. A software of the occlusal adjustment and the form modification were developed. It is also the first time, the authors realized the whole process to use the CAD-CAM for the manufacture of a crown. CONCLUSION: The successful result shows, that we have already mastered well the base theory, the mathematics method, the technology of a CAD-CAM system. It provides the basics for the future development.
