The curable composition for dental use comprises (A) a polymerizable monomer mixture containing a polymerizable monomer having an acidic group in the molecule and (B) a polymerization initiator, wherein in the component (A), (A’) a long-chain polymerizable monomer having a structure with a chain length of 17 atoms or more is contained, and/or in the composition, (D1) a soft resin material is further contained, and Formulae (1) to (5) are satisfied in the case where the amount of the component (A’) is denoted by [a’] (parts by weight) when the amount of the component (A) is taken as 100 (parts by weight), and the amounts of the components (A), (B), and (D1) are denoted by (a), (b), and (d1) (parts by weight), respectively, when the total amount of the component (A) and the component (B) is taken as 100 (parts by weight): 70 ≤ (a) ≤ 99.99 (1); 0.01 ≤ (b) ≤ 30 (2); 1 ≤ [a’]/5+(d1)/1 (3); [a’] ≤ 95 (4); and (d1) ≤ 250 (5).
A dental polymerizable composition which is a two-pack type self-curing resin. It has satisfactory applicability by the brush-on technique or mixing technique, in particular, satisfactory applicability by the brush-on technique. It is reduced in air bubble inclusion and excellent in color tone, polishability, unsusceptibility to discoloration upon curing and after curing, mechanical properties, etc. The composition is usable for many purposes, e.g., the repair of a denture base or artificial tooth, a final tooth crown prosthesis, or a temporary prosthesis which is used until a bridge is completed. The dental polymerizable composition comprises three (meth)acrylic ester polymer powders each having specific particle size characteristics and specific molecular-weight characteristics.
Disclosed is a reaction-setting adhesive composition having an acidic nature, which comprises: a weakly acidic to alkaline composition (I) comprising a polymerizable monomer (a) and a compound (b) represented by the formula (1); and a strongly acidic composition (II) comprising the polymerizable monomer (a). R1-C6H4-NR2CH2COOR3 (1) wherein R1 and R2 independently represent a hydrogen atom or an alkyl group which may have a functional group; and R3 represents a hydrogen atom or a metal atom. It becomes possible to store a composition containing a polymerizable monomer for a long period.
A self-etching primer composition for dental use, which comprises a mixture containing a polymerizable monomer, a reductive inorganic compound containing sulfur, a ketone-series solvent and water and has a storage stability at 65oC of 2 hours or longer, and a kit.
