title: Autotransplantation of a maxillary third molar to replace a maxillary premolar with vertical root fracture.
abstract: OBJECTIVE
  To report the successful autotransplantation of a fully developed third molar that required nonsurgical and surgical interventions for tooth adaptation.
  
  
  CONCLUSIONS
  This case report describes the autotransplantation of a third molar with complete root development after the loss of a fractured premolar in a 47-year-old male. To allow better adaptation of the donor tooth, the buccal roots of the third molar were removed using a diamond bur and the canal entrances were filled. Recall examination 6 years after completion of root-canal treatment showed normal periodontal healing with absence of infection, ankylosis or progressive resorption. The transplantation of a third molar is seen as a promising method to replace a lost permanent tooth, and to restore aesthetics and function.
  
  
  CONCLUSIONS
  *Autotransplantation is a viable option for the treatment of a missing tooth or for replacement of traumatized tooth when there is a donor tooth available. *Fully developed third molars are potentially reliable candidates in the absence of other suitable donor teeth.
