title: Replantation of a displaced incisor in a boy with a cleft lip and alveolus: a case report.
abstract: BACKGROUND
  Tooth replantation after traumatic avulsion or transplantation is a challenge in oral surgery. A special method named auto-alloplastic replantation, in which a titanium post is used after extraoral endodontic treatment, combines several advantages. The treatment is performed in one step with no further endodontic intervention, no wide root canal instrumentation, no recontamination, and reduced endodontic infection. This is the first report on replantation of an ectopic tooth in a patient with a cleft lip and alveolus using this method.
  
  
  METHODS
  This case report presents the treatment of a 13-year-old white boy with a cleft lip and alveolus who had an ectopic incisor in the cleft region. His rehabilitation was performed by a tooth transposition using the auto-alloplastic replantation technique. After preparation of the displaced incisor from the vestibule, extraoral endodontic treatment followed using a titanium post prior to replantation in a newly formed socket. In the follow-up, the tooth is still in place and functioning after 2 years.
  
  
  CONCLUSIONS
  This method can be used to bridge the years while a patient is young and jaw growth is incomplete until bone augmentation and implantation can be performed. The tooth will preserve the remaining alveolar ridge and help the adolescent psychologically.
