[The study of a computer aided artificial teeth arrangement of complete denture].
OBJECTIVE
To develop a system of computer aided complete denture design (CACDD).


METHODS
After 3 dimensional measurement, data process and making model of a edentulous model, artificial teeth and the maxillomandibular bite plate, on the position of centric relation, the artificial teeth were arranged according to the principle and demand of the complete denture's teeth arrangement. The relation of teeth and occlusion were adjusted by Affine and Projection transformation.


RESULTS
(1) The maxillomandibular visual base on the position of centric relation were made, its mathematics model is B-Spline curve surface of the double third power. (2) The artificial teeth arrangement and 3 dimensional show of the complete denture were achieved.


CONCLUSIONS
This system can provide a feasible tool for a computer aided complete denture design and teaching.
