Abstract
Replantation is the reinsertion of a tooth in its socket after its complete avulsion as a result of trauma or accidental extraction. Intentional replantation is intentional removal of a tooth and its reinsertion into the socket after endodontic manipulation and/or obturation of the canal or both. Intentional replantation is used as a last measure to preserve a tooth when there is no alternative treatment except extraction. When posterior teeth are involved, root preservation might not be feasible because of the proximity of the mandibular canal,mental foramen, or maxillary sinus or because of technical difficulties, such as a lack of accessibility or density of the bone structure.
Intentional replantation is rarely resorted to because the indications for this operation are few.
We present two cases of intentional replantation. Mandibular first molar (first case) and second molar (second case) were diagnosed as having chronic apical periodontitis and endodontic treatment was determined to be impractical. Although we believed that extraction was the preferred treatment, intentional replantations were performed as a last resort. The follow-up of both cases radiographically revealed periapical repair.
