During the manufacture of complete denture, the most important step is to design and generate the dental arch curve which adapts to the requirement of patients according to the jaw arch morphology of them. It is important to study the optimization method of the number and position of control point for the dental arch generator. On the basis of motion analysis of the dental arch generator, objective function, multivariate design and constraint function of control point optimization of dental arch generator is determined. Control points number and position of the dental arch generator is optimized. Simulation results verify the feasibility of control point optimization method.
