[Ceramic canal pins]

In restorative dentistry, any technique that employs retentive endoradicular pins can be associated with a simple technique that includes ceramization of the metallic surface of the pin, producing great adhesion to a composite resin by interposition of a silane coupling agent. The strong bond obtained using this technique between pin and filling material surrounding it prevents a dangerous concentration of mechanical forces around the pin itself and reduces the probability of breaks and consequent failure of the restoration.
