Here we describe replantation and transplantation as a treatment conducted in a 16-year-old patient following a bicycle accident. An avulsed left central incisor in maxilla was replanted after extra-oral root canal treatment, and the lost right central incisor of the maxilla was replaced by a left lateral incisor of the mandible in the region of the fracture fissure. Follow-up examination at 34 months showed validity of treatment, although slight evidence of replacement resorption in the transplanted and replanted teeth was revealed.
