<p>A dental composition useful for an artificial tooth and an artificial tooth with use of the said dental composition by which color stability, coloring resistance and aesthetic merit can be maintained for a long period of time and which have superior characteristics such as bending strength, impact strength, hardness and wear resistance. The dental composition comprises (A) at least one monomer and/or oligomer selected from methacrylates and acrylates, (B) an uncrosslinked polymer selected from homopolymers of methacrylates, acrylates and styrene; copolymers of at least two monomers selected from methacrylates, acrylates and styrene; mixtures of the homopolymers; mixtures of the copolymers; and mixtures of the homopolymer(s) and the copolymer(s), (C) a crosslinked polymer selected from homopolymers of methacrylates, acrylates and styrene; copolymers of at least two monomers selected from methacrylates, acrylates and styrene; mixtures of the homopolymers; mixtures of the copolymers; and mixtures of the homopolymer(s) and the copolymer(s), (D) an organic and inorganic filler complex, and optionally (E) an inorganic filler. The said dental composition is used to make a dough. which is polymerized and molded into an artificial tooth.</p> |
