Orthodontic-aided extraction of impacted third molar to improve the periodontal status of the neighboring tooth.

Objectives: In the present clinical report, we describe the management and the long-term (3-year) outcome of a periodontally compromised lower second molar healed by orthodontic-aided extraction of the neighboring impacted third molar. Methods: A healthy 21-year-old woman referred signs and symptoms of pericoronitis of impacted tooth 48 and periodontal injury on the distal aspect of tooth 47. The wisdom tooth was surgically exposed, and an orthodontic appliance was anchored to the neighboring teeth to stimulate eruption. After 5 months, third molar could be easily extracted. Results: Three years after extraction, clinical and radiographic controls revealed a complete healing of the periodontal defect. Conclusions: Orthodontic-aided extraction of impacted third molars may improve the periodontal status of the neighboring tooth. This protocol is not free from drawbacks and limitations and should be applied only when third-molar extraction is associated with a concrete risk of postoperative complications.
