Application of surgical locating guides on impacted supernumerary teeth extraction / 华西口腔医学杂志

ABSTRACT

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.
