中文摘要
目的 探讨基于锥形束CT（CBCT）和计算机辅助设计/制造（CAD/CAM）技术的手术定位导板在埋伏多生牙拔除中的应用。方法 选择上颌前区埋伏多生牙患者15例,通过CBCT确定手术入路方式,CAD/CAM技术设计制作唇侧入路手术导板或腭侧入路手术定位导板,并应用到手术中定位拔除埋伏多生牙。结果 手术定位导板在术中均贴附良好,可迅速定位并暴露多生牙,同时避让邻近重要解剖结构。结论 手术定位导板在埋伏多生牙拔除中可以精确定位及减少手术创伤。
英文摘要
ObjectiveTo 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 super-numerary teeth.MethodsThis 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 fabri-cated by CAD/CAM technique. Impacted supernumerary teeth were extracted under the location of surgical locating guides.ResultsSurgical 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.ConclusionSurgical locating guides benefit the accurate detection and reduction of trauma in extraction of impacted supernumerary teeth.
