Dental adhesive composition.

摘要

Disclosed are dental adhesive compositions consisting essentially of (a) at least one urethane prepolymer containing one or more isocyanate groups, or a blend of the urethane prepolymer and an inert diluent; (b) at least one radical-polymerizable unsaturated monomer; (c) a photopolymerization initiator; and, if desired, (d) a polymerizable phosphoric ester compound having a specific structure. These dental adhesive compositions can be used to bond a restorative material to dentin without requiring any troublesome pretreatment with an etching agent such as phosphoric acid, and can exhibit bonding power sufficient for practical purposes.
