A 16-years old female patient was referred to our observation in July 2006, 14 days after an accident, with traumatic intrusive luxation of the right upper central incisor that caused the nasal floor and buccal cortical bone fracture. While the extraoral examination showed the traumatic lesions of the upper lip, the intraoral examination revealed intrusive luxation, pain and high mobility of the tooth, and bleeding of the adjacent oral tissue. The treatment protocol consisted in surgical buccal bone removal, tooth extraction, retrograde root-canal filling, and tooth repositioning in occlusion with a resilient splinting. After 8 weeks the splinting was removed, and clinical and radiological examinations were taken 3, 6, 9, 12, and 24 months after surgery. At the 24 months follow-up the root showed no radiographic signs of inflammation, resorption or ankylosis, and the function of the replanted tooth was fully maintained. Tooth replantation can be considered an effective alternative to dental implant, when the latter is contraindicated in young patient with incomplete skeletal development. The long-term success of the procedure will likely require a multidisciplinary approach.
