目的:评价锥体束CT(CBCT)在埋伏牙诊断及治疗中的临床应用价值。方法:选择常规全颌曲面断层片和X线牙片不能准确定位的埋伏阻生牙28例,术前对所有患者进行CBCT扫描获得高分辨率影像,并使用专用软件进行准确定位。结果:28颗埋伏阻生牙均被精确定位,采用最佳手术入路后,均顺利拔除或成功牵引至正确位置。结论:CBCT是判断埋伏阻生牙准确位置的有效方法,在埋伏阻生牙诊断及治疗中有重要的临床应用价值。
Objective: To evaluate the clinical value of cone beam computed tomography (CBCT) in the diagnosis and treatment of impacted teeth. Methods: Totally 28 cases of impacted nasal impacted teeth with conventional maxillary curved surfaces and X-ray dental implants were selected. All patients underwent CBCT scan before surgery to obtain high-resolution images. The software was used to accurately locate them. Results: Twenty-eight ambush impacted teeth were accurately positioned. After optimal surgical approach, they were successfully removed or successfully towed to the correct position. Conclusion: CBCT is an effective method to determine the accurate location of impacted impacted teeth. It has important clinical value in the diagnosis and treatment of impacted impacted teeth.
