Abstract

[Object] 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.

Claims (9)

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.

2. The method of producing a plate denture according to claim 1 , wherein

the artificial tooth and the denture base are adhered to each other in a fitted state.

3. The method of producing a plate denture according to claim 1 , wherein

the second polymerization initiator is a radical polymerization initiator.

4. The method of producing a plate denture according to claim 1 , wherein

the second polymerization initiator is a photopolymerization initiator having an excitation wavelength different from that of the first polymerization initiator.
