WebOct 6, 2024 · Following the introduction of glass ionomer cement (GIC) in 1972, resin modified glass ionomer (RMGI) was developed in 1988 by adding a small amount of resin to glass ionomer. The resin allows for light curing, giving clinicians the ability to fully set the material in-office, thus preventing water absorption that can lead to problems with GICs. 7
