<P>PROBLEM TO BE SOLVED: To easily manufacture dental prosthesis having excellent quality similar to the natural texture of a tooth, in tooth treatment. <P>SOLUTION: The shapes of the tooth are measured before and during the tooth treatment to prepare three-dimensional design data of the dental prosthesis on the basis of the shape data of the tooth, and the three-dimensional design data is input to a three-dimensional printer to built up the material of the dental prosthesis on the basis of the three-dimensional design data to bake the same. The color of the dental prosthesis is determined on the basis of the color data of the tooth obtained by imaging the tooth before treatment and the three-dimensional design data to prepare three-dimensional printed data. The material of the dental prosthesis is laid on the basis of the three-dimensional printed data by the three-dimensional printer and coated with a colorant selected on the basis of the three-dimensional printed data to be built up while coloring the material of the dental prosthesis. Furthermore, the preliminarily colored material of the dental prosthesis is used as a printing material, and a material to be used in later building-up is lighter in color and higher in transparency. <P>COPYRIGHT: (C)2012,JPO&INPIT |
