【発明の詳細な説明】 ［産業上の利用分野］ 本発明は、ポリサルポン床義歯の補修材に関する。[Detailed description of the invention] [Industrial application field] The present invention relates to a repair material for polysarpon dentures.

Instant polymerization resin is a resin that is a mixture of a liquid component consisting of methyl methacrylate and amine and methyl methacrylate polymer powder containing peroxide, and can be repaired by filling the resin into the repair area and curing it. be done.

雑な工程が必要であった。However, polysulfone dentures crack due to contact with methyl methacrylate. Therefore, when conventional instant polymerization resins are used as they are, strength and aesthetics deteriorate. Further, fine cracks also occur when using acrylic repair materials other than those mentioned above, which are commercially available as repair materials for polysulfone dentures. Therefore, prior to repair, a complicated process of applying a pretreatment agent to the surface of the polysarpon denture base, drying it, and then filling the repaired area with a repair material was necessary.

ルホン義歯床の補修材に関する。That is, the present invention provides a polysulfone denture comprising a methyl methacrylate polymer shell containing 20 to 40% by weight of a methyl methacrylate polymer having a molecular weight of too much to 150,000, and a methyl methacrylate polymer containing peroxide. Regarding floor repair materials.

化する。また、補修材の接着強度も低下する。If the molecular weight of the methyl methacrylate polymer is less than 10,000, the adhesive strength of the repair material is insufficient and it cannot be put to practical use. If it exceeds 150,000, the viscosity of the methyl methacrylate solution becomes extremely high, making it difficult to use. becomes worse. Furthermore, the adhesive strength of the repair material also decreases.

補修材の接着強度も低下する。If the methyl methacrylate polymer concentration is less than 20% by weight, cracks will occur in the areas where the repair material is applied. When it exceeds 40% by weight, the viscosity of the methyl methacrylate solution becomes extremely high, resulting in poor operability. Also,
The adhesive strength of the repair material also decreases.

られなかった。Example 1 A methyl methacrylate polymer produced by emulsion polymerization was added to a methyl methacrylate solution containing 25% by weight of a methyl methacrylate polymer with an average molecular weight of 105,000, to which a small amount of N,N-dimethyl-p-toluidine was added. A repair material was prepared by mixing the powder with 1% by weight of benzoyl peroxide added. The repair material was applied and fixed to a thickness of 2 loam between the mating end faces of two polysulfone sheets having a length of 50 mm, a width of 4 mm, and a thickness of 4 mm. This test piece was tested using an Instron universal testing machine at a distance between chucks of 50 mm and a tensile speed of 10 mm/min. As a result, the adhesive strength was 320 kg/cffl. Furthermore, no cracks were observed in the polysulfone around the area where the repair material was applied.

The test was carried out in the same manner as in Example 1, except that a methyl methacrylate solution containing 35% by weight of 50,000 methyl methacrylate polymer was used. As a result, the adhesive strength was 310 kg/cal. In addition, this repair material was applied to an actual polysulfone denture base with a diameter of 3 mm.
When it was filled into holes with a depth of 21 mm, no cracks were generated in the surrounding polysulfone denture base, and an extremely good cured product was obtained.
