Process for preparing dental prosthesis

摘要

A measuring center stores three-dimensional coordinate information of an intra-oral shape measured by impression taking as a digital signal. The measuring center sends the obtained measured data to a design center using communication apparatus. The design center reproduces the intra-oral shape on a graphic display device based on the received measuring data as a three-dimensional graphic, designs a shape of a dental prosthesis and stores it as a digital signal. The processing center transmits the received design data to a milling processor as a processing command and subjects a block material to milling processing to prepare a dental prosthesis.
