摘要：

PROBLEM TO BE SOLVED: To provide a rigid plate which has the simulated three-dimensional shape of molar and premolar teeth used in manufacturing dentures, complete dentures in particular, and which makes it possible to simply, precisely, and smoothly perform a difficult operation such as determining the positional relation between the upper jaw and the lower jaw.

SOLUTION: The rigid plate 1 having the simulated three-dimensional shape of the molar and premolar teeth used in manufacturing the dentures, the complete dentures in particular has a size of covering a section corresponding to the right or left molar and premolar teeth of a U-shaped occlusion rim 2 made from paraffin wax placed on a resin base plate 4. On the top surface of the rigid plate 1, an upper shape 1i with the simulated three-dimensional shape composed of a first premolar tooth, a second premolar tooth, a first molar tooth, and a second molar tooth in order from the front is formed protrusively. The upper shape 1i with the simulated three-dimensional shape composed of the molar and premolar teeth projects from the flat surface of the occlusion rim. On the rear surface or the bottom of the rigid plate 1, a fixation means for fixing the same to the occlusion rim is provided.
