Reinforced glass-ionomer cements--a review of properties and clinical use.
In recent years, two new metal-reinforced Glass-ionomers have been introduced.  The aim has been to develop a cement which can be used successfully as a replacement for amalgam.  This paper reviews the published literature on the mechanical properties and clinical use of both the cermet and so-called 'Miracle Mix' cements. The published results do not suggest an improvement in strength or adhesion to tooth material; wear resistance is improved, however. One problem encountered in reviewing this literature is the wide variation in test methodology and hence results.  In clinical use, the metal-reinforced cement has been successful in Class I and II restorations, particularly using the tunnel technique, and has potential for use in a number of other applications.
