Current clinical concepts for adhesive cementation of tooth-colored posterior restorations.

The adhesive luting of tooth-colored posterior restorations has long been considered an unreliable clinical procedure. The physical and clinical properties of former base lining materials, the absence of an effective peripheral biological seal during provisionalization, and the use of less than optimal adhesive systems and luting cements have prevented the achievement of satisfactory clinical results. This article describes effective procedures for adhesive cementation based on the application of distinctive layers and the use of densely filled, viscous luting materials.
