title: Orthodontic extrusion anchored in osseointegrated implants: a case report.
abstract: Rapid orthodontic extrusion is indicated for cases involving biological space invasion of the periodontal ligament in which the surgical increase of the clinical crown can compromise esthetics or the support of the adjacent teeth. This article presents the case report of a tooth with radicular perforation 1.0 mm below the bone crest. A procedure to restore the biological distances was necessary. Rapid orthodontic extrusion of the affected tooth, with anchorage in the adjacent osseointegrated implants, was selected.
