Abstract
PURPOSE:To obtain color data of a state near to a natural tooth different in a color state at respective regions, by dividing an adjacent tooth into a plurality of regions in displaying the color image of said tooth and replacing each of the regions with a teeth color sample. CONSTITUTION:The adjacent tooth of a tooth to be treated is photographed under a definite illumination condition by a color camera 11 to be displayed on the picture of a color CRT 12. Then, the adjacent tooth 17 displayed on the color CRT 12 in a magnified state is divided into regions as shown by broken lines and replaced with a shade guide at every region. The color data thus obtained of the adjacent tooth and a floppy disk 13 having the number selection data of the shade guide stored therein are regenerated on the picture of the color CRT 12 and an artificial tooth is prepared after the regenerated image.
