Autotransplantation of an Inverted Maxillary Premolar

This case report describes the treatment of an inversely impacted maxillary first premolar in a 12.6-year-old girl by autotransplantaion and comprehensive orthodontic treatment. Four months after surgery, brackets were placed, and orthodontic force was applied. After orthodontic treatment, the transplanted premolar showed favorable stability and occlusion with a little short root length. This case demonstrates a successful treatment modality for an inversely impacted premolar with prolonged retention of a primary molar.
