Abstract: [Problem]
To provide a dental adhesive composition realizing excellent durable adhesive strength with respect to various dental restorative materials for cutting and machining such as glass ceramics containing lithium disilicate, a dental resin for cutting and machining, and a dental resin for cutting and machining made of a glass fiber reinforced resin in particular and with respect to a tooth substance, and having excellent storage stability simultaneously.
[Solution]
The dental adhesive composition of the present invention comprises a matrix containing (A1) silane coupling material represented by structural formula of [Chemical formula 1], (B) polymerizable monomer having an acidic group and (C) polymerizable monomer having no acidic group, and wherein the (C) polymerizable monomer having no acidic group contains (C1) polymerizable monomer having no acidic group and having one or more hydroxyl groups, the (A1) silane coupling material represented by structural formula of [Chemical formula 1] and the (C1) polymerizable monomer having no acidic group and having one or more hydroxyl groups coexist in at least one matrix, and the dental adhesive composition satisfies at least one of following formulas (1) and (2). 0.005≤Total amount of silane coupling material compounding amount index in matrix ((S1×W1)/M1)≤0.070   [Formula (1)] 0.001≤Total amount of silane coupling material compounding amount index in composition ((S2×W2)/M2)≤0.015   [Formula (2)]
