Tooth loss treatment in the anterior region: autotransplantation of premolars and cryopreservation.

Avulsed and lost anterior teeth are common in young people. Using autotransplantation, it is possible to move problems in dental arches to regions where they are more easy to solve orthodontically. Transplantation of premolars with three-quarter root formation or full root formation with wide-open apical foramina provides the best prognosis for long-term survival. This article describes the use of autotransplantation and orthodontic treatment, together with cryopreservation, in connection with complicated trauma in the anterior region of an 8-year-old girl.
