title: Retrospective long-term evaluation of autotransplantation of premolars to the central incisor region.
abstract: OBJECTIVE
  This retrospective case-series study aimed to examine the long-term outcomes of autogenously transplanted premolars.
  
  
  METHODS
  Twelve patients in whom donor premolars were used to replace maxillary central incisors lost by trauma were clinically and radiologically monitored. Standardized clinical and radiographic records were systematically obtained during the follow-up period of 14 years, to determine the influence of specific clinical criteria on the overall success rate of transplantation.
  
  
  RESULTS
  The success rate of premolar autotransplantation in the maxillary central incisor area was 80% after 14 years follow-up. The highest success rate occurred in those teeth transplanted with two-thirds of full root development. Complete pulp obliteration was positively related to autotransplant viability, followed by root formation in the bony crypt.
  
  
  CONCLUSIONS
  Autotransplantation of donor teeth, at the stage of ½ to ¾ of their expected root length, can provide a successful treatment solution for over 14 years.
