Orthodontic treatment of an open bite case with congenitally missing teeth using premolar autotransplantation

In cases of congenitally missing teeth, it is useful to combine autotransplantation and orthodontic space closure. We treated a 12-year-old girl who showed a slight anterior open bite with congenitally missing teeth and impaction of the maxillary canine. The molar relationships were Angle Class II. We attempted traction of the maxillary canine after surgical exposure. However, we could not move it and suspected it to be ankylosed. A mandibular premolar was transplanted into the maxillary anterior region. After active treatment, a porcelain fused to metal crown was placed to restore aesthetic appearance labially. Occlusion remained stable during 4 years and 9 months of follow-up. At 8 years and 6 months post-transplantation, the donor tooth remains both clinically and radiographically healthy.
