[Application of double miniscrews for extraction of horizontally impacted wisdom tooth with high risk of injury to inferior alveolar nerve].

PURPOSE: To study the clinical effect of double miniscrews for extraction of horizontally impacted wisdom tooth adjacent to the inferior alveolar nerve canal.

METHODS

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.

RESULTS

After extraction, no patient developed lip numbness.

CONCLUSIONS

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.
