Single-Component dental composition containing silane coupling agent and acidic group-containing polymerizable monomer

Abstract

The present invention provides a one-component dental adhesive composition which can exhibit excellent adhesion to both materials of a dental ceramics and an organic composite containing an inorganic compound, and is excellent in can-stability. More particularly, the present invention provides a one-component dental adhesive composition comprising 1 to 60 parts by weight of (a) a silane coupling agent, 1.0 to 20.0 parts by weight based on 100 parts by weight of the (a) component of (b) an acidic group-containing polymerizable monomer, and 28 to 99 parts by weight of (c) a volatile organic solvent.
