The present invention provides a resin composition for optical shaping that, with its low viscosity, enables easy stereolithographical fabrication of an object, and that can produce an object having desirable toughness and desirable water resistance, particularly for dental mouthpieces and denture base materials. The present invention relates to a resin composition for optical shaping comprising a urethanized (meth)acrylic compound (A) and a photopolymerization initiator (B), the urethanized (meth)acrylic compound (A) being a (meth)acrylate containing at least one polyol moiety and a urethane bond per molecule, said at least one polyol moiety being selected from the group consisting of a polyester, a polycarbonate, a polyurethane, and a polyether each having a structure derived from a C4 to C18 aliphatic chain diol unit (a) having a branched structure.

To provide a method of producing a plate denture using a stereolithography 3D printer, which is capable of producing a plate denture in a short time with a more simplified production process, the plate denture exhibiting excellent occlusion. [Solving Means] The problem is solved by a method of producing a plate denture, including: adhering an artificial tooth and a denture base photochemically solidified by a stereolithography 3D printer to each other by polymerizing an unpolymerized curable composition for stereolithography present on a surface of the denture base. Further, stronger adhesion between the artificial tooth and the denture base is achieved by mixing, in the curable composition for stereolithography, a polymerization initiator other than a photopolymerization initiator for stereolithography.

A dental prosthesis is provided, manufactured from a one-piece or multi-piece prosthesis blank which is composed of a gum-colored material (14) and a tooth-colored material (14), especially each one being based on plastic material. The tooth-colored material (14) of the blank (10) has a diameter or a width of more than 5 cm and especially a substantially flat cylindrical shape with a diameter/height ratio of more than 2:1, preferably more than 3:1. The gum-colored and tooth-colored materials (14, 12) are bonded together by bonding, polymerization and/or integral production. The boundary (16) between the materials, as viewed in the direction of the dental arch course, is wave-shaped with alternating grooves and ribs (22, 24), and in the region of the anterior arch in the vestibular direction—is of radiant shape.

Provided is a denture base that includes a base portion; a socket that is demarcated by a step portion from a gingival area of the base portion and to which an artificial tooth is to be attached; and interdental papilla areas of the gingival area, which are positioned at both ends of the socket along a tooth row, wherein, in a state in which the socket is facing upward, a basal surface of the socket has a ridge-shaped socket apex portion configured by a surface that is convex overall, a peripheral area of the basal surface is in mutually continuous abutment with the step portion, and the socket apex portion is positioned at substantially the same height as, or higher than, apex portions of the interdental papilla areas that are seen from a labial side in a state in which the artificial tooth is attached to the socket.
