DENTAL RESTORATION PRODUCING SYSTEM FOR PRODUCING DENTAL RESTORATION FROM DENTAL MILL BLANK WITH THROUGH-HOLE, OPERATION SYSTEM OF THE SYSTEM, PROGRAM FOR THE SYSTEM, AND DENTAL MILL BLANK FOR USE IN THE SYSTEM

摘要

A dental restoration producing system of producing a dental restoration from a dental mill blank with one or more through-holes according to one embodiment, when the dental restoration includes no through-hole of the dental restoration, the superposed data generating section generates a superposed data in which at least one through-hole of the dental mill blank is not superposed with the dental restoration, when the dental restoration includes a through-hole of the dental restoration, the superposed data generating section generates a superposed data in which at least one through-hole of the dental mill blank is not superposed with the dental restoration and the through-hole of the dental restoration, or a superposed data in which at least one through-hole of the dental mill blank is included in the through-hole of the dental restoration which is larger than the at least one through-hole of the dental mill blank.

主权项

1. A dental restoration producing system of producing a dental restoration from a dental mill blank with one or more through-holes, comprising;
a data taking-in section taking in a dental mill blank shape data which indicates a shape of a dental mill blank and includes a position data of one or more through-holes, and a dental restoration shape data which indicates a shape of a dental restoration to be produced, a superposed data generating section generating a superposed data in which the dental restoration is superposed in the dental mill blank based on the dental mill blank shape data and the dental restoration shape data, and a control section controlling cutting of the dental mill blank based on the superposed data, wherein, when the dental restoration includes no through-hole of the dental restoration, the superposed data generating section generates a superposed data in which at least one through-hole among the one or more through-holes of the dental mill blank is not superposed with the dental restoration, when the dental restoration includes a through-hole of the dental restoration, the superposed data generating section generates a superposed data in which at least one through-hole among the one or more through-holes of the dental mill blank is not superposed with the dental restoration and the through-hole of the dental restoration, or a superposed data in which at least one through-hole among the one or more through-holes of the dental mill blank is included in the through-hole of the dental restoration which is larger than the at least one through-hole among the one or more through-holes of the dental mill blank, and the control section controls cutting so that cutting is started from the at least one through-hole among the one or more through-holes of the dental mill blank.
