  • Title: Esthetics with glass-ionomer cements and the "sandwich" technique.
    Author: Mount GJ.
    Journal: Quintessence Int; 1990 Feb; 21(2):93-101. PubMed ID: 2197665.
    Abstract:
    The Type II restorative esthetic glass-ionomer cement has not been generally regarded as a useful esthetic restorative. However, as long as its relatively slow-setting chemistry is understood and accepted and provision is made to maintain the water balance for the first 24 hours, it can be just as useful as composite resin. Taking into account the fluoride release, its tissue compatibility, and the chemical union with underlying tooth structure that is available, it is suggested that it has a valuable place in restorative routines. Manufacturers have been encouraged recently to try to produce a fast-setting cement that can be polished at the insertion appointment. A varnish to seal newly placed restorations is supplied by most manufacturers, but these are not completely waterproof. A low-viscosity, single-component, light-activated resin bonding agent has been shown to work satisfactorily as a sealant, and, with its use, it is possible to develop adequate translucency and optimal physical properties in the oral cavity.
