Compomers are dental restorative materials that are a composite of composite resins and glass ionomer cements. They are biocompatible and release fluoride, making them effective for restoring anterior teeth. Compomers have aesthetic qualities allowing for color selection, are photopolymerizable for quick curing, and have acid-base properties. However, they have low resistance to direct chewing forces and require a careful mixing technique when first applied. Common brands include Dyract and Hytac.
