Replacing resorbed maxillary central incisors with mandibular premolars. 1990

Institute of Dentistry, University of Oulu, Finland.

A case report is presented on autotransplantation of a lower premolar into the upper central incisor area. A traumatized upper central incisor lost because of external root resorption was replaced by a premolar transplant taken from a crowded mandibular arch. The transplant showed excellent adaptation and the periapical inflammation noticed a few years after the operation was treated successfully with apicectomy.
