Intentional replantation. A viable alternative for selected cases.

When conventional endodontic treatment or retreatment is not possible, the operator may choose to intentionally extract and replant the involved tooth. Intentional replantation consists of extracting the tooth, finding and correcting the defect, and replanting the tooth in its socket. This article discusses the indications, contraindications, and recommended techniques for intentional replantation. Several successful case reports are described in which intentional replantation was used as a last resort.
