Resin-modified glass ionomer cements. Resin-modified glass ionomer cements were developed to overcome the problems of moisture sensitivity and low initial mechanical strength. They consist of a GIC along with a water-based resin system which allows photopolymerization to occur before the acid–base reaction of the glass ionomer is complete.
