Intentional tooth replantation is a last-resort procedure, recommended only when all other techniques, short of tooth ext raction, have been exhausted or are impractical. Although most endodontic textbooks describe the procedure, and many reports of intentional replantation have appeared in the dental literature, none have reported use of the technique to retain a removable partial denture abutment tooth. This article presents such a case and the rationale for the decision to intentionally replant. Eighteen-month follow-up clinical and radiographic results are presented.
