Over the last 10 years or so, there have not ben advances in resin modified glass ionomer cements until now. GC America brought their new FujiCem Evolve to the market and took this category of materials a giant step forward.
I will admit to being a skeptic when it was announced. I wondered how can we improve on something that is really awesome already? What are they going to change in a material that has ben in dentistry for a very long time? Despite my skepticism I am now a raving fan of this product.
I wish I could tell you the science behind what they have improved, but I can’t as the information is proprietary. What I can tell you is what I have experienced clinically that has convinced me to use this now in my practice routinely. First, an incredible gel phase with easy clean up. I hit the restoration for 3 seconds per line angle using a quarter technique and the cement is super easy to pull off. Second, really amazing chemical retention. Glass ionomer cements are designed to be used for restorations with mechanical retention. Having a cement where the physical properties of the cement give it durability and longevity to retain the restoration is an incredible addition, and Evolve has done just that. As with all glass ionomers Evolve is low technique sensitivity and creates great patient comfort post-operatively.
