Conventional Wisdom and the Surgical Exposure of Impacted Teeth

The aim of thie presentation is to provide evidence against the notion that direct contact between the crown of an impacted tooth and alveolar bone is an impediment to orthodontically assisted eruption of teeth. A closed eruption surgical technique was used to expose the impacted teeth in which a wide soft tissue flap was reflected, but only a small window was opened into the dental follicle of the impacted tooth, leaving a maximum amount of bone covering much of the crown surface. Orthodontic extrusion forces were then applied.

A series of patients affected by impacted teeth is reported, including individuals who were normal healthy patients, with and without resorption of the adjacent incisor roots, as well as individuals suffering from Cleidocranial dysplasia and increased bone density, and individuals with autogenous and synthetic bone grafts. For all teeth, enamel-to-bone contact did not prevent a rapid response to the extrusive forces. This permits the conclusion that radical removal of bone during the exposure of an impacted tooth is unnecessary and potentially may be harmful in terms of the periodontal prognosis of an otherwise successfully treated outcome.
