[Objective] To research the rudimental methods of computer-aided design of full crown prosthesis. [Methods] A gypsum working cast and die of a full crown was scanned with a mechanical scanner, and the surface data were acquired. On the platform of commercial CAD software, the whole process of the computer-aided design of full crown was realized, the standard teeth crown models which were established in former experiments were used to define the basic contour of the prosthesis.[Results] The CAD data of a full crown were achieved, including inner surface as well as outer surface, the data were integrated and precise. [Conclusion] The methods of this research were practical and feasible and could lay the foundations of the development of dental CAD/CAM system.
