Explanation: The Vitremer core buildup/restorative system, manufactured by 3M ESPE, is comprised of shaded glass ionomer powders, the glass ionomer liquid, the primer and a finishing gloss. 
Vitremer core buildup/restoration is a two-part, powder/liquid composition.
The powder is a radiopaque, fluoroaluminosilicate glass. The liquid is a light-sensitive, aqueous solution of a modified polyalkenoic acid. 
Vitremer core buildup/restoration provides the major benefits of glass ionomer cements - adhesion to tooth structure, fluoride release and biocompatibility.
