摘要： A measured object mounting tool 2 for producing a three-dimensional shape data comprises a placing part 2b at the lower face of a cylindrical part 2a, an inclined part 2c at a boundary 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 three-dimensional coordinate other than the engaging portion 3a of a model 3 is produced by engaging the model of the dental prosthesis with the mounting part 2e of the tool 2 on a placing table 1; detecting a position where a received light amount is remarkably decreased to by a laser sensor detect a lower end of the inclined part 2c; and thereby calculating an upper end of the engaging portion 3a.

摘要： Designing of a coping for proper working is made possible. Based on three-dimensional data on a model of an abutment tooth to which a dental prosthesis is applied stored in RAM (Random Access Memory) and on three-dimensional position information about a margin line of the model stored in another RAM, on a face containing a reference axis of the model, three-dimensional position information about a side face of a coping is determined so that a specified angle is formed between a margin line and a surface of the model and three-dimensional position information about the side face of the coping on each of a plurality of different faces containing the reference axis over an entire circumference in a direction surrounding the reference axis is detected by a coping processing section.

摘要： A fabrication aiding apparatus capable of easily and properly setting a margin line is provided. The apparatus includes a RAM (Random Access Memory) to store three-dimensional shape data on a model of an abutment tooth to which a dental prosthesis is applied, an accepting section to accept the input of specification of an angle formed between a line defining a contact point and a reference axis on a face containing the reference axis in the model, a contact point detecting section to detect, based on the three-dimensional shape data, three-dimensional position information about a contact with the line forming a specified angle with the reference axis on the face containing the reference axis in the model, and a margin determining section to determine, based on coordinates of a contact point, three-dimensional position information of a margin line in the model.
