ABSTRACT:
A measured object mounting tool2for producing a three-dimensional shape data comprises a placing part2bat the lower face of a cylindrical part2a, an inclined part2cat a boundary between the side face and the upper face of the cylindrical part2a, and a pillar part2dat the upper face of the cylindrical part2a, where the pillar part2dhas a mounting part2eat the upper face thereof, a three-dimensional coordinate other than the engaging portion3aof a model3is produced by engaging the model of the dental prosthesis with the mounting part2eof the tool2on a placing table1; detecting a position where a received light amount is remarkably decreased to by a laser sensor detect a lower end of the inclined part2c; and thereby calculating an upper end of the engaging portion3a.
