Document Type and Number:
Japanese Patent JP2811725
Kind Code:
B2
Abstract:
PURPOSE:To facilitate execution of lining back side by using soft resin by a method wherein, after a photopolymerization type laminated resin sheet formed by bringing a photopolymerization type resin sheet into surface adhesion with a soft resin sheet is molded on a model to form a false tooth bed, the false tooth bed is irradiated with light, artificial teeth are arranged on the false tooth bed by using photopolymerization type resin to form a gum. CONSTITUTION:After a photopolymerization type laminated resin sheet 2 formed by bringing a photopolymerization type resin sheet 21 into surface adhesion with a soft resin sheet 22 is molded on a model 1 to form a false tooth bed, an artificial teeth 4 are arranged on the false tooth bed, produced by irradiating the false tooth bed with light, by means of photopolymerization type resin 5 to form a gum. A resin plate is formed with the photopolymerization type resin sheet 21, the soft resin sheet 22, and an adhesion layer, located between the photopolymerization type resin sheet 21 and the soft resin sheet 22 and bringing the two sheets into surface adhesion with each other through the medium of the adhesion layer. Photopolymerization type resin is a composition in which a photo sensitizer having maximum absorption at a wavelength of 380-700nm is added to a methacrylate or acrylate type monomer. This composition enables to make a false tooth, the mucous membrane surface of which is lined back side with soft resin, easily and in a short time.
