1. A method for manufacturing a plate denture including a denture base and an artificial tooth placed on the denture base, the method comprising:
preparing three-dimensional data for an artificial tooth impression that is an impression for the artificial tooth to be placed on the denture base, and three-dimensional data for the plate denture;
preparing a denture mold including a bottom wall, a side wall extending upward from the bottom wall, a forming space which is surrounded by the bottom wall and the side wall and into which a denture base material is to be poured, a retained portion disposed on the side wall and to be directly or indirectly attached to a cutting apparatus, a cutting target region located in the bottom wall and to be cut by the cutting apparatus so as to define a groove for the artificial tooth, and a plurality of vent holes defined in the bottom wall, passing through the bottom wall in an up-down direction, and in communication with the forming space;
cutting the denture mold including directly or indirectly attaching the denture mold to the cutting apparatus through the retained portion, and cutting the groove in the cutting target region in accordance with the three-dimensional data for the artificial tooth impression;
placing the grooved denture mold on a holder so as to close the plurality of vent holes, the holder being higher in gas permeability than the denture mold;
placing the artificial tooth in the groove;
curing the denture base material including pouring the denture base material into the forming space, with the artificial tooth placed in the groove, and curing the denture base material so as to fabricate a one-piece product including the denture mold, the artificial tooth, and a cured product of the denture base material that are integral with each other; and
machining the one-piece product including directly or indirectly attaching the one-piece product to the cutting apparatus through the retained portion, and machining the cured product in accordance with the three-dimensional data for the plate denture.
