A method to strengthen a nonvital immature maxillary central incisor during long‐term endodontic therapy is described. Calcium hydroxide paste was packed into the root canal space, then removed to a level 3 mm apically to the osseous crest. A layer of IRM cement was placed over the paste to provide a bacteria‐tight seal. The coronal portion of the root canal as well as the pulp chamber were acid‐etched and filled with a composite resin in an attempt to strengthen the tooth. Access to the root canal was maintained by means of a vaseline‐coated plastic post placed centrally in the resin. After polymerization of the resin the post was removed and the space was sealed with zinc oxide and eugenol cement. After completion of the endodontic treatment the space was filled with the composite resin.
