To study the clinical effect of double miniscrews for extraction of horizontally impacted wisdom tooth adjacent to the inferior alveolar nerve canal. Eight horizontally impacted wisdom teeth requiring extraction because of orthodontic treatment were proven to be adjacent to the inferior alveolar nerve canal by means of cone-beam CT scan. The treatment began with double miniscrews traction under the help of cantilever beam. After 6~9 months, they left the canal and then were extracted. After extraction, no patient developed lip numbness. Application of double miniscrews traction is an efficient and reliable method for extraction of horizontally impacted wisdom tooth that is adjacent to the inferior alveolar nerve canal.
