<prompt> Vitremer is ___Metal modified GICResin modified GICOrganically modified compositePolyacid modified composite  <response>: The Vitremer core builduprestorative system, manufactured by 3M ESPE, is comprised of shaded glass ionomer powders, the glass ionomer liquid, the primer and a finishing gloss. Vitremer core builduprestoration is a two-part, powderliquid composition.The powder is a radiopaque, fluoroaluminosilicate glass. The liquid is a light-sensitive, aqueous solution of a modified polyalkenoic acid. Vitremer core builduprestoration provides the major benefits of glass ionomer cements - adhesion to tooth structure, fluoride release and biocompatibility.Reference-
