摘要：
In order to improve preciseness and installation convenience, the present invention provides a digital overdenture manufacturing method comprising: a first step of acquiring a three-dimensional work image including surface information of a target arch of a prosthetic patient； a second step of arranging, on the three-dimensional work image, a virtual fixture corresponding to implant information of a fixture from a digital library, and extracting a virtual attachment to be coupled to an inner circumferential fastening groove of the virtual fixture so as to virtually arrange same； a third step of designing a virtual digital overdenture by arranging, inside an assembly groove profile designed on the basis of the surface information of the target arch, a virtual coupling groove having a marginal space configured according to a preset allowance gap from an outer surface profile of a virtual housing cap to which the virtual attachment is to be coupled； a fourth step of manufacturing, in correspondence to the design information of the virtual digital overdenture, a digital overdenture having a coupling groove corresponding to the virtual coupling groove； and a fifth step of correcting, in the marginal space, a position error between an attachment corresponding to the virtual attachment, a housing cap corresponding to the virtual housing cap, and the coupling groove, so as to fix same to each other.La présente invention concerne un procédé de fabrication de prothèse dentaire numérique, visant à améliorer la précision et la facilité d'installation. Le procédé comprend : une première étape consistant à acquérir une image de travail tridimensionnelle comprenant des informations de surface d'une arcade cible d'un patient prothétique ； une deuxième étape consistant à placer, sur l'image de travail tridimensionnelle, un appareil virtuel correspondant à des informations d'implant d'un appareil, provenant d'une bibliothèque numérique, et à extraire un élément d'attache virtuel à acc
