1. A method of producing a plate denture characterized by comprising:
preparing a denture base having an artificial-tooth-arrangement recessed portion by stereolithography by a 3D printer using a curable composition for stereolithography including a first polymerization initiator for stereolithography and a second polymerization initiator different from the first polymerization initiator, an unpolymerized portion including the second polymerization initiator being present on a surface of the denture base; and
directly adhering, after arranging an artificial tooth in the artificial-tooth-arrangement recessed portion, the artificial tooth and the denture base to each other without using an adhesive by causing the second polymerization initiator to act to polymerize the unpolymerized portion present on the surface of the denture base.
