While dental amalgam is still the most widely used cavity filling material for the direct restoration of defects in posterior teeth, the retention of amalgam filling is due entirely to macromechanical containment in the undercut cavity. The same holds true for the silicate filling materials, which have for many decades been used for anterior restoration. These two classes of restoratives are therefore outside the scope of this chapter. Of interest as adhesion-active filling materials under the present heading are the glass ionomer cements, including their metal-reinforced varieties (cermets), and the composite resins.
