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.

摘要

目的

研究基于锥形束计算机断层扫描(CBCT)和计算机辅助设计/计算机辅助制造(CAD/CAM)技术的手术定位导板在埋伏多生牙拔除术中的应用。

方法

本研究纳入15例上颌前部埋伏多生牙患者。通过CBCT确定手术入路。采用CAD/CAM技术设计并制作唇侧入路或腭侧入路的手术定位导板。在手术定位导板定位下拔除埋伏多生牙。

结果

手术定位导板在手术中贴合良好。埋伏多生牙迅速被定位并暴露,同时避免了相邻重要解剖结构。

结论

手术定位导板有助于准确拔除埋伏多生牙并减少创伤。
