Resin cements are the most versatile and widely used cements for non-metallic restorations, resin-bonded fixed partial dentures, ceramic crowns that can be etched, and porcelain veneers, as well as ceramic and resin composite inlays and onlays.
Resin cements with a dentin bonding agent have provided a threefold increase in crown retention on teeth with short clinical crowns compared to using zinc phosphate cement. Resin cements used today are composed of resin matrix of bis-GMA or urethane dimethacrylate and filler of fine inorganic particles to ensure thin film thickness. They are available as powder/liquid, encapsulated, or paste/paste systems and are classified into three types based on the method of polymerization as chemical-cured, light-cured and dual-cured. It has many advantages like; Superior compressive and tensile strengths with low solubility, available in wide range of shades and translucencies, micromechanical bonding to prepared enamel, dentin, alloys and ceramic surfaces.
