This article reports a clinical case of a 10-year-old boy who sustained an avulsion of the maxillary right central incisor. The avulsed tooth was kept in adverse extraoral dry conditions for 26 hours from the moment of trauma until its replantation. Treatment guidelines for avulsed mature permanent teeth with closed apex were only partially followed. However, the clinical and radiographic findings after 10 years revealed acceptable functional outcome, in spite of ankylosis and root resorption of the replanted tooth, which was eventually treated cosmetically.
