Abstract:
A dental composition comprising:(A) at least one monomer and/or oligomer selected from the group consisting of methacrylates and acrylates,(B) an uncrosslinked polymer selected from the group consisting of homopolymers of methacrylates, acrylates and styrene; copolymer of at least two monomers selected from the group consisting of methacrylates, acrylates and styrene; mixture of the homopolymers; mixture of the copolymers; and mixture of the homopolymer(s) and the copolymer(s),(C) a crosslinked polymer selected from the group consisting of homopolymers of methacrylates, acrylates and styrene; copolymer of at least two monomers selected from the group consisting of methacrylates, acrylates and styrene; mixture of the homopolymers; mixture of the copolymers; and mixture of the homopolymer(s) and the copolymer(s), and(D) an organic and inorganic filler complex produced by a process comprising admixing powdered inorganic filler with a methacrylate or acrylate monomer, polymerizing said monomer and then pulverizing the resultant product.
