摘　　要：目的观察锥形束CT(CBCT)在上颌前部埋伏牙术前定位诊断中的应用。方法选取2017年8月至2019年2月本院口腔科接收的78例门诊X线检查确定上颌前部有埋伏牙的患者,采用CBCT进行术前定位诊断,确定埋伏牙的具体位置。结果 78例患者中上颌前部埋伏牙牙数为97枚。其中56例(71.79%)患者含一枚埋伏牙,14例(17.95%)患者含2枚埋伏牙,8例(10.26%)患者含3枚埋伏牙。上颌中切牙38枚,上颌侧切牙9枚,上颌尖牙50枚。结论 CBCT三维重建在上颌前部埋伏牙术前定位诊断中能准确显示埋伏牙的位置、形态、萌出方向及与邻牙和周围组织的空间位置关系,具有临床应用价值。Objective To observe the application of cone beam computed tomography (CBCT) in preoperative localization diagnosis of maxillary-anterior embedded dentes.Methods 78 patients with maxillary-anterior embedded dentes confirmed by outpatient X-ray examination in stomatology department of the hospital between August 2017 and February 2019 were selected.CBCT was used for preoperative localization diagnosis to determine the specific location of the impacted teeth.Results There were 97 maxillary-anterior embedded dentes in the 78 patients,including 56 patients (71.79%) with one embedded tooth,14 patients (17.95%) with 2 embedded teeth,and 8 patients (10.26%) with 3 embedded teeth.There were 38 maxillary central incisors,9 maxillary lateral incisors,and 50 maxillary canines.Conclusion The application of three-dimensional reconstruction of CBCT in preoperative localization diagnosis of maxillary-anterior embedded dentes can accurately display the position,shape and eruption direction of the embedded teeth and the spatial position relationship with adjacent teeth and surrounding tissues,with clinical application value.
