Until recently, adequate bone at the recipient site has been a determinant for tooth autotransplantation. This article presents the transplantation of developing mandibular canines to a suboptimal position because of inadequate bone at the recipient sites. Five years later, after eruption and orthodontic alignment, all criteria for successful healing were fulfilled. In addition, new bone that was not present at the time of surgery was identified at the roots of the transplanted teeth, implying that transplanted developing teeth can stimulate bone to grow along their roots.
