Composition for priming and adhering to tooth structure

(57) The composite and method of dealing with the summary tooth surface and pasting up restoration material on the tooth surface with which it dealt are offered. A liquid composite is applied to at least 1 dental portion, and the surface with which it dealt is formed. This composite contains the volatile organic solvent at least 15 % of the weight and effective amount of lights initiator for one or more polymerization nature acrylate compounds at least 50% of the weight. At least 1 portion of this polymerization nature compound is a polyfunctional polymerization nature compound which has at least three アクリ rate 残 machines. This polymerization nature compound is 可溶 substantially to this solvent. This composite conforms to forming the polymer material which suits pasting dentine by the joint intensity of at least 12 MPa (s). Next, restoration material is pasted up on the surface with which it dealt by the joint intensity of at least 12 MPa (s). This polymer material has the surrender intensity of at least 50 MPa (s), an elastic coefficient of at least 1, 000 MPa (s), the elastic strain energy of at least 0.4 MPa (s), and/or at least 90% of initial 辺縁 completeness after dental etching.
