Autotransplantation of premolars. A retrospective study.

The purpose of this clinical follow-up study was to evaluate the success rate of autotransplantation of human premolars. In the period between 1982 and 1994, 46 premolars in 31 patients were transplanted. A long-term success rate of 97.5% with a mean follow-up period of 3.5 years was achieved. It seems to be justified, therefore, in selected cases, to consider the possibility of autotransplantation as a good alternative to orthodontic or prosthetic treatment, including implant insertion, when closing a gap in the dental arch.
