Apport des techniques d’autogreffes dentaires à l’orthodontie

[Autotransplantation of a maxillary incisor and orthodontic care: a case study]

INTRODUCTION

Severely impacted teeth with atypical root anatomy do not respond well to orthodontic traction after surgical exposure. Consequently, they are often removed, but replacing them with dental prostheses can prove difficult in patients who are still growing. Thus, autotransplantation seems to be the only way to preserve a natural tooth and the alveolar bone.

MATERIALS AND METHODS

An upper central incisor impacted in the region of the nasal cavities with an open apex was diagnosed in an 8.5-year-old female patient. The tooth displayed a curved root pressed against the maxillary cortical bone preventing orthodontic traction treatment. Through this clinical case involving autotransplantation of a maxillary incisor report and a review of the literature, this article explores the indications and exposes the different stages of this orthodontic-surgical protocol.

RESULTS

In this case, autotransplantation enabled restoration of maxillary arch continuity. After two years of orthodontic treatment, the bone reconstruction of the extraction site was very satisfactory.

DISCUSSION

The benefits of this technique and the precautions to be taken are discussed as well as the various protocols. The increasing success rate of this surgical procedure makes it possible to consider it as a protocol for the future.
