Although non-surgical endodontic procedures have high success rates, failures do occur, These can be managed by root canal re-treatment or surgical intervention. Intentional replantation is an accepted endodontic treatment procedure in which a tooth is extracted and treated outside the oral cavity and then inserted into its socket to correct an obvious radiographic or clinical endodontic failure. Intentional replantation is indicated when other endodontic treatments performed to maintain the tooth have failed, or when endodontic periradicular surgery is not feasible. Intentional replantation may be particularly useful in these cases because these difficult to access areas can be maximally treated while the tooth is out of the mouth without damaging the periodontal attachment in adjacent teeth. In conclusion, intentional replantation is a reliable and even predictable procedure, and should be considered more often as a treatment modality in our efforts to maintain the natural dentition.
