| Abstract: | Objective To study and develop a Chinese made coping crown CAD system for clinical application. Methods Preparation teeth data were retrieved by the optical measuring system; VC6.0 and HOOPS were used to develop CAD software for coping crown design; the coping crown was fabricated with themini high-speed NC milling machine. Results A software of a CAD system of the coping crown and the whole process with the CAD/CAM technique for the manufacture of a coping crown were actualized. Conclusion The dental coping crown designed and fabricated by this system was steady and precise. |
