Simplify Your Office's Luting Process With GC

All cements are different, from glass ionomers to resins. Remembering how to use each of them, especially cements that are new to your practice, can be confusing at times. While these products always include instructions for use, and usually technique cards, keeping track of all these items can be a hassle. Luckily, the digital age has simplified instructional use, making it easier to learn how to use these new products and incorporate them into your daily procedures.

GC Luting Guide is an excellent app available for free on the Google Play Store and Apple App Store, which showcases all of GC America’s cements with their indications and step by step use.
