Resin pins: a novel composite resin concept for treatment of posterior teeth--technical presentation.
With the evolution of bonding systems, various techniques have been proposed to reduce polymerization shrinkage and postoperative sensitivity in posterior direct resin restorations. It has been noted that the result could be improved using various layers, due to the contractions that occur proportionally to the quantity of material and the intensity of the curing light during polymerization. This article reviews the use of small, prepolymerized composite resin pearls or inserts compressed against the surface of the tooth wall to reduce the volume to be polymerized. The use of resin pins enables superior bonding to the dental structure, incrementing the marginal adaptation and reducing postoperative sensitivity.
