CA 2506945

The dental adhesive composition of the present invention comprises a polyfunctional polymerizable monomer which is an ester compound of a polyhydric alcohol of 3 to 6 carbon atoms and plural (meth)acrylic acids and has 1 to 2 hydroxyl groups, a monofunctional (meth)acrylate having no hydroxyl group in its molecule, a polymerizable monomer containing an acid group in its molecule, an organoboron compound as a curing agent and a filler. According to the present invention, a dental adhesive composition remarkably enhanced in the curing rate with rarely affecting adhesion properties of the composition, working time and flexibility of a cured product is provided.

Une composition dentaire adhésive est caractérisée en ce qu'elle comprend: un monomère polymérisable multifonctions qui est un ester possédant une structure constituée d'un groupe fonctionnel de polyalcool et deux ou plusieurs groupes hydroxy; un (méth)acrylate contenant aucun groupe hydroxy dans la molécule; un monomère polymérisable contenant un groupe acide dans la molécule; un composé de bore organique utilisé comme agent de durcissement M; et une charge. La composition dentaire adhésive peut se polymériser à une vitesse extrêmement élevée sans avoir pratiquement aucune influence sur les performances de liaison et la durée de fonctionnement de la composition et sur la flexibilité de la composition après sa polymérisation.
