Water Sorption of Light Cured Resin Cement: The Effect of Ceramic Material and Thickness

Abstract

Ceramic materials have several appealing properties making it highly on demand. As esthetics have become of major importance, ceramic’s fluorescence, natural look, chemical stability and biocompatibility made its usage favorable. The success of ceramic restorations depends on obtaining a strong, durable bond between the resin cement and dentin/enamel. The magnitude of these bonds is directly proportional to an adequate cement polymerization. Polymerization is crucial for achieving optimal physical properties and satisfactory clinical performance of resinous materials.

When cementing laminate veneers with light cured resin cements, it is important to understand that the different ceramic materials and veneer thicknesses may attenuate the light. These veneers are not all equal; they may differ not only in color, opacity and thickness but also in composition and manufacturing technique. Thus, understanding of how different types and thicknesses of ceramic veneers may influence the degree of conversion of light-cured resin-based cements could assist the clinician in choosing the best restorative and luting material in order to provide esthetic and functional results with a safe and durable effect.

The present study showed the effect of ceramic material type and its thickness on the water sorption of the light cured resin cement when three different ceramics were used with twothicknesses.
