Implant Site Development by Orthodontic Extrusion and Buccal Root Torque at a Site Showing Severe Gingival Recession with Periodontitis: A Case Report.

This case report describes alveolar ridge augmentation around a hopeless maxillary canine with severe buccal gingival recession and periodontitis using orthodontic extrusion and a 90-degree buccal root torque in preparation for implant placement. After the orthodontic therapy, the palatal surface of the canine root reached the top of the alveolar bone, parallel to the occlusal plane, with newly formed bone and keratinized mucosa. An implant was successfully placed without combined bone augmentation. This technique may be a useful, minimally invasive approach for implant site development where hopeless teeth with severe buccal recession remain in the esthetic areas.
