Management of crown-root fracture tooth by intra-alveolar transplantation with 180-degree rotation and suture fixation.

Teeth with traumatic crown-root fractures extending subgingivally and involving the entire width of the tooth may have problems in endodontic isolation, periodontal maintenance, and restoration. A number of techniques, such as crown lengthening, and orthodontic or surgical extrusion, have been described for treatment of crown-root fractures. However, all of these techniques have limitations in terms of the extended time required for treatment, cost, and esthetic considerations. Intra-alveolar transplantation is an alternative treatment option in the management of complicated crown-root fractures. We describe a case of intra-alveolar transplantation with 180( degrees ) rotation and suture fixation. At 1-year follow-up, the replanted tooth has normal function and no obvious inflammatory root resorption on radiographic examination.
