Definitions

  • Materials used for denture bases include acrylic resins, polycarbonate resins, and polysulfonic acid resins, with acrylic resins based on polymethyl methacrylate and polyethyl methacrylate being the most commonly used.
  • the materials used for coating are generally (meth)acrylic monomers, and the materials used for backing materials are mostly mixtures of (meth)acrylic monomers and polymers. It is no exaggeration to say that this is the only practical case.
  • urethanized (meth)acrylic acid ester compounds From the viewpoint of exhibiting particularly high curability and easily obtaining high adhesion durability, urethanized (meth)acrylic acid ester compounds, aromatic compound-based (meth)acrylic acid ester compounds that do not contain urethane bonds, and It preferably contains at least one selected from alicyclic (meth)acrylic acid ester compounds, urethanized (meth)acrylic acid ester compounds, and aromatic compound-based (meth)acrylic acid esters that do not contain urethane bonds At least one selected from compounds is more preferable, and a urethane-modified (meth)acrylic acid ester compound is particularly preferable.
  • the urethanized (meth)acrylic acid ester compound does not contain a polymer structure, there is no concept of weight average molecular weight, so the molecular weight is applied. If the weight-average molecular weight is 1,000 or less, it becomes easier to prevent an increase in viscosity and a decrease in permeability. From the viewpoint of adhesion durability to a molded oral appliance, the weight average molecular weight is more preferably 750 or less, and even more preferably 500 or less. Furthermore, the urethanized (meth)acrylic acid ester compound is preferably a compound that does not contain a polymer structure, such as polyester, polycarbonate, polyurethane, and polyether.
  • a polymer structure such as polyester, polycarbonate, polyurethane, and polyether.
  • the curable composition for stereolithography (A) contains other polyfunctional (meth)acrylic acid ester-based polymerizable monomers
  • the curable composition for stereolithography (A) contains other poly
  • the content of the functional (meth)acrylic acid ester-based polymerizable monomer is preferably 1 to 50% by mass and 5 to 40% by mass in 100% by mass of the curable composition for stereolithography (A). %, more preferably 8 to 35% by mass.
  • the total content of the polyfunctional (meth)acrylic acid ester polymerizable monomer (a-1) in the curable composition for stereolithography (A) is equal to the (meth)acrylic polymerizable monomer (a ) is preferably 10 to 100 parts by mass with respect to 100 parts by mass of the total mass of ), and more preferably 30 to 90 parts by mass from the viewpoint of excellent adhesion durability to the stereolithographically shaped intraoral device. It is more preferably 50 to 80 parts by mass.
  • Monofunctional (meth)acrylic acid ester polymerizable monomers include aromatic ring-containing (meth)acrylic acid ester polymerizable monomers, alicyclic (meth)acrylic acid Ester polymerizable monomers, nitrogen atom-containing cyclic (meth)acrylic acid ester polymerizable monomers, chain (meth)acrylic acid ester polymerizable monomers, cyclic (meth)acrylamide compounds, chain (Meth)acrylamide compounds and the like.
  • the (meth) acrylic acid ester polymerizable monomer containing an aromatic ring the (meth) acrylic, which tends to have a high boiling point and is less likely to feel an odor.
  • Acid ester-based polymerizable monomers, nitrogen atom-containing cyclic (meth)acrylic acid ester-based polymerizable monomers, and cyclic (meth)acrylamide compounds are preferred.
  • a (meth)acrylate polymerizable monomer containing an aromatic ring is more preferred.
  • the curable composition for stereolithography (A) is not particularly limited as long as it contains the (meth)acrylic polymerizable monomer (a) and the photopolymerization initiator (b). It may contain other ingredients.
  • the curable composition for stereolithography (A) can be produced according to a known method.
  • additives can be added to the curable composition for stereolithography (A) for the purpose of adjusting the color tone or adjusting the paste properties.
  • the additives include pigments, dyes, thickeners, polymers, prepolymers (oligomers), and aryl compounds (eg, aryliodonium salts).
  • An additive may be used individually by 1 type, and may use 2 or more types together.
  • step 2B processing such as grinding and polishing is performed as necessary.
  • processing such as grinding and polishing is performed as necessary.
  • machining marks, polishing marks, and the like are formed on the surface of the coating film, and as a result, the coating film has processing marks.
  • a coated denture base or coated denture which is a coated oral appliance, is obtained.
  • the adhesive strength is 5 MPa or more, it can be used in clinical practice, if it is 10 MPa or more, it will be as good as the conventional method, and if it is 15 MPa or more, it will be extremely superior to the conventional method. be.
