Digital denture manufacturing method and manufacturing system, and denture hole guider applied thereto and manufacturing method thereof

A digital denture manufacturing system comprising:

• an imaging apparatus configured to acquire a three-dimensional (3D) 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 shown and an auxiliary scan image for a temporary denture in which a binding region formed to correspond to an abutment fastened to a fixture implanted in a target dental arch is arranged;
• a planning unit configured to acquire, from the auxiliary scan image, a correction surface image on three-dimensional (3D) surface information of an inner surface-side engagement groove of the temporary denture including the binding region, set an inner surface profile according to the 3D surface information of the engagement groove, and set a virtual binding groove corresponding to a position and shape of the 3D surface information of the binding region in the inner surface profile so that a digital denture is designed;
• a manufacturing apparatus configured to manufacture the designed digital denture;
• and
• a digital library storage including profiles according to types of the abutment,
• wherein the planning unit replaces and corrects the 3D surface information of the binding region with a virtual abutment extracted from the digital library and virtually disposed and sets the virtual binding groove corresponding to the virtual abutment so that the digital denture is designed,
• wherein the planning unit virtually arranges the virtual abutment extracted from the digital library corresponding to the abutment to correspond to the 3D surface information of the binding region included in the correction surface image and replaces to correct the 3D surface information of the binding region along an outer periphery region of the virtual abutment, and
• wherein the planning unit virtually arranges a virtual digital denture in which an artificial gum portion and an artificial teeth portion are set on the basis of the 3D work image that is replaced and matched with the correction surface image and designs the digital denture such that the virtual digital denture is matched with the virtual binding groove to correspond to an overlap region between the virtual digital denture and the virtual abutment.
