Definitions
- the present disclosure relates to compositions for dental materials and dental materials.
- a dental material composition such as a composite resin generally contains a dental material composition containing a monomer, a filler, a polymerization initiator, a polymerization inhibitor, a pigment, and the like.
- a radically polymerizable polyfunctional methacrylate composition is sometimes used from the viewpoints of in-vivo safety of the monomer and mechanical strength and abrasion resistance of the cured product.
- Patent Document 1 describes an amine compound (A) having two or more amino groups, an iso(thio)cyanate compound (B) having two or more iso(thio)cyanate groups, and one polymerizable group.
- a (meth)acrylate (D) which is a reaction product of the above-mentioned hydroxy (meth)acrylate compound (C) is described.
- a wide variety of bacteria reside in the oral cavity, and these bacteria form dental plaque starting from sugar, leftover food, etc., and eventually form a biofilm. Biofilm formation can be suppressed by antibacterial agents, antifouling coats, etc.
- antibacterial agents have problems such as biological safety and initial digestion
- antifouling coats have problems such as complicated processing and easy peeling.
- compositions for dental materials containing a monomer and simple silver as an antibacterial component.
- an antibacterial component there is room for improvement in antibacterial properties of dental material compositions containing silver alone.
- sulfur components that cause bad breath exist in the oral cavity, and when a dental material composition containing silver ions is used in the oral cavity, this composition, a dental material containing a cured product of the composition, There is a problem in that the material tends to turn black over time.
- the present disclosure has been made in view of the above, and provides a dental material composition that has excellent antibacterial properties and suppresses discoloration due to sulfur components, and a dental material containing a cured product of this dental material composition. With the goal.
- a composition for dental materials comprising inorganic particles carrying at least one metal component selected from the group consisting of silver and zinc, a (meth)acrylate compound, and a polymerization initiator.
- the inorganic particles contain one or more compounds selected from the group consisting of aluminosilicate and phosphate glass.
- the content of the inorganic particles is 0.01% by mass to 15% by mass with respect to the total amount of the composition for dental materials. .
- the content of the inorganic particles according to any one of ⁇ 1> to ⁇ 3> is 0.01 parts by mass to 40 parts by mass based on 100 parts by mass of the (meth)acrylate compound.
- Composition for dental materials ⁇ 5>
- the composition further contains a filler other than the inorganic particles, and the content of the filler other than the inorganic particles is 50% by mass or less based on the total content of fillers contained in the dental material composition.
- the dental material composition according to any one of ⁇ 1> to ⁇ 4> which does not contain fillers other than the inorganic particles.
- a dental material comprising a cured product of the dental material composition according to any one of ⁇ 1> to ⁇ 7>.
- a dental material composition that has excellent antibacterial properties and suppresses discoloration due to sulfur components, and a dental material containing a cured product of this dental material composition.
- numerical ranges indicated using “ ⁇ ” include the numerical values written before and after " ⁇ " as minimum and maximum values, respectively.
- the upper limit or lower limit described in one numerical range may be replaced with the upper limit or lower limit of another numerical range described step by step.
- the upper limit or lower limit of the numerical range may be replaced with the values shown in the Examples.
- “(meth)acryloyl” means acryloyl or methacryloyl
- “(meth)acrylate” means acrylate or methacrylate.
- the dental material composition refers to a composition in which the dental material composition itself, a cured product of the dental material composition, or a product obtained by further processing the cured product can be used as a dental material. means.
- the amount of each component in a composition if there are multiple substances corresponding to each component in the composition, unless otherwise specified, the amount of each component in the composition is means the total amount.
- the specific inorganic particles may be read as silver-supported zeolite, zinc-supported zeolite, silver-zinc-supported zeolite, silver-supported zirconium compound, zinc-supported zirconium compound, or silver-zinc-supported zirconium compound.
- the dental material composition of the present disclosure comprises inorganic particles (hereinafter also referred to as "specific inorganic particles") on which at least one metal component selected from the group consisting of silver and zinc is supported, and (meth)acrylate It contains a compound and a polymerization initiator.

- the dental material composition of the present disclosure includes at least one of silver-supported inorganic particles, zinc-supported inorganic particles, and silver and zinc-supported inorganic particles as specific inorganic particles. include. This provides excellent antibacterial properties and suppresses discoloration due to sulfur components. More preferably, by using specific inorganic particles, the antibacterial effect can be easily maintained for a long period of time and discoloration such as blackening can be suppressed compared to the case where silver alone is used.
- Metals such as silver alone and zinc exhibit excellent antibacterial properties, but when used in dental materials such as dental composite resins, adhesives, and cement materials, they may cause color changes during product storage or after product use. is remarkable.
- dental materials such as dental composite resins, adhesives, and cement materials
