PROCÉDÉ DE FABRICATION DE PROTHÈSE DENTAIRE NUMÉRIQUE ET SYSTÈME DE FABRICATION, ET GUIDE D'ORIFICE DE PROTHÈSE DENTAIRE APPLIQUÉ À CELUI-CI ET SON PROCÉDÉ DE FABRICATION
In order to improve manufacturing convenience and precision, the present invention provides a digital denture manufacturing method comprising: a first step of acquiring a three-dimensional work image, on which occlusion information between a target dental arch and an opposing dental arch and implant information of a fixture implanted in the target dental arch are displayed, and preparing a temporary denture in which a binding region formed to correspond to a binding portion profile of an abutment fastened to the fixture is arrayed and arranged； a second step of acquiring an auxiliary scan image for the temporary denture； a third step of acquiring, from the auxiliary scan image, a correction surface image on three-dimensional surface information of an inner surface-side engagement groove of the temporary denture including the binding region； and a fourth step of designing and manufacturing a digital denture having a virtual binding groove corresponding to the position and the shape of the three-dimensional surface information of the binding region, in an inner surface profile set according to the three-dimensional surface information of the engagement groove.
