| Summary: | A resin composition for denture is provided, which does not require operations for weighing, and mixing during the use; is free from involving of air bubbles; and when used for preparation of a denture base, is free from a reduction in physical properties and staining or discoloration with a lapse of time. Further, a completed denture has a high elastic energy value, is superior in impact resistance, and when applied with an impact or a stress as in the case of dropping, is not readily broken. The resin composition for denture base is in a one-paste state and is constructed by (a) a polymerizable monomer and/or oligomer having a modulus of elasticity at polymerization of 0.25 to 3.00 GPa, (b) an organic filler and/or an organic-inorganic composite filler having a modulus of elasticity of 0.25 to 3.00 GPa, and (c) a polymerization initiator made of a heat polymerization type polymerization initiator and/or a photopolymerization type polymerization initiator, and optionally, (d) an inorganic filler. |
