PROBLEM TO BE SOLVED: To provide a production method of a double crown which achieves an easier production and moreover, a high attaching-detaching flexibility with a higher accuracy. SOLUTION: There are arranged a means by which the shape of a dental lost portion is measured to obtain measurement data, a means to obtain data for the formation of a margin line from the measurement data, a means to obtain data for the formation of a division line based on the data for obtaining the margin line, a means by which coupling shape data are added to each of separation measurement data obtained based on the division line to combine the both and a means by which a prosthetic mass is worked based on the separation measurement data to produce a separation prosthesis. |
