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.
目的
开发具有自主知识产权的牙科CAD/CAM系统。
方法
使用新型三维激光扫描仪对28个标准牙冠进行扫描。以Matlab 5.3作为开发平台，用于处理采集到的数据，也用于定义牙冠表面的特征区域并改变牙冠形态。使用Surfacer 10.5软件开发用于固定修复体的新CAD软件，并使用三轴数控机床制造修复体。
结果
首次建立了具有标准形态的中国牙冠三维图形数据库。开发了咬合调整和形态修改软件。作者也是首次实现了使用CAD-CAM制造牙冠的全过程。
结论
成功结果表明，我们已很好地掌握了CAD-CAM系统的基础理论、数学方法和技术。为未来的发展提供了基础。
