する時間が非常に長い欠点がある。Conventional technology Conventional hard dental lenone is a dental metal casting that fits into an abutment tooth from which the affected area of the caries has been removed, and is made of a mixture of methyl methacrylate monomer, methyl methacrylate, and pigment. The mixture is cured by heating in a polymerization kettle or flask for about 30 minutes. The mixture is repeatedly coated and cured to obtain the desired shape and color tone. The Nutz hardness Hk of prepared dentures is approximately 20~
It is 30. As mentioned above, conventional dental hard resins have the disadvantage that their hardness during molding is low and that it takes a very long time to mold dentures.

ある。As the silicon dioxide, it is possible to use a repellent powder surface-treated with γ-methacryloxypropyltrimethoxysilane, amorphous silica (manufactured by Aerosil Co., Ltd.), and the like. The silicon dioxide is used to make the composition into a paste form and to impart hardness and strength to the formed denture.

がよシ強力に行なわガるためと思わする。For example, benzoyl peroxide is used as the organic peroxide. When only the acrylic monomer is processed in a commercially available microwave oven, the surface of the cured resin remains unreacted. Mixing organic peroxides into acrylic monomers completely converts the monomers into resins. This is thought to be due to the exothermic effect of microwaves and the action of active radicals generated by the decomposition of organic peroxides due to the heat, which makes the polymerization curing reaction more powerful.

できる。The composition of the present invention can be sold in a form in which the acrylic yarn, silicon dioxide, organic peroxide, and pigment are contained in one container, or the composition components can be divided into an appropriate number of containers. You can also sell it. It is also possible to create a fidget composition by mixing pigments of a basic number of tones and sell it as a set of compositions that have all the desired tones by mixing them.

は短時間に完了する。In the conventional method using a polymerization pot and flask, the air and water surrounding the acrylic monomer are heated, and the acrylic monomer is heated using the heated air, air, and water. However, curing of the acrylic monomer in a microwave oven is carried out by the heat generated by the acrylic monomer itself and by the action of the organic peroxide, so that curing is completed in a short time.
