[Application of surgical locating guides on impacted supernumerary teeth extraction].

OBJECTIVE

To study the application of surgical locating guides based on cone beam computed tomography (CBCT) and computer-aided design/computer-aided manufacturing (CAD/CAM) technique on extraction of impacted supernumerary teeth.

METHODS

This study included 15 patients with impacted supernumerary teeth in anterior maxillary. Surgical approach was determined by CBCT. Surgical locating guides of labial approach or palatal approach were designed and fabricated by CAD/CAM technique. Impacted supernumerary teeth were extracted under the location of surgical locating guides.

RESULTS

Surgical locating guides were well attached in the operation. The impacted supernumerary teeth were located and exposed rapidly, and the adjacent important anatomical structures were avoided.

CONCLUSIONS

Surgical locating guides benefit the accurate detection and reduction of trauma in extraction of impacted supernumerary teeth.
