A technique to reinforce weakened roots with post canals

Abstract A method to strengthen the weakened coronal portion of roots with post canals is described. The apical portion of the root canal is prepared using a Dormer twist drill to fit a matching Wiptam wire post. After removal of the Wiptam wire, the root canal of the weakened coronal portion of the root is prepared and acid-etched. The Wiptam wire, lubricated with petroleum jelly, is repositioned into the root canal, and after painting the coronal root den tin with bonding agent, radiopaque composite resin is syringed around the wire into the coronal defect. Following polymerization of the composite material, the wire is removed, leaving a reinforced root with a patent post canal. Preparation of the root face is completed for restoration with a post crown.
