Preparation method of a three-dimensional shape data of dental prosthesis using the same object to be measured and attachment

摘要

To provide a measured object mounting tool used for producing a three-dimensional shape data of a part other than an engaging portion of the dental prosthesis by a three-dimensional measuring device. The engaging portion has a projected and/or recessed engaging part and a cross sectional shape having a shape other than the rotary body, and is projected on a jawbone side. The three-dimensional measuring device comprises a rotary table having a Z axis as an axial center, XY table fixed with a putting table, and a measuring part for measuring by one laser sensor. A measured object mounting tool (2) comprises a putting part (2b) at the lower face of a cylindrical part (2a), an inclined part (2c) at a boundary part between the side face and the upper face of the cylindrical part (2a), and a pillar part (2d) at the upper face of the cylindrical part (2a), where the pillar part (2d) has a mounting part (2e) at the upper face thereof. A method of producing three-dimensional shape data of dental prosthesis using that tool is also disclosed.
