摘　　要：目的探讨MSCT齿科重组在颌骨埋伏牙诊断和治疗中的临床价值。方法对20例埋伏牙病例进行256层螺旋CT扫描,并通过Dental planning软件进行齿科全景重组后处理,对埋伏牙进行定位诊断。结果 20例患者共27颗埋伏牙均被精确定位,埋伏牙的牙体形态、位置以及与邻牙的关系均清晰显示,并根据Dental planning软件分析最佳手术入路后均顺利拔除埋伏牙。结论 MSCT全景齿科重组是一种高效准确的定位诊断埋伏牙的方法,在埋伏牙拔除的方案制定中有重要的指导价值。Objective To investigate the clinical application of multi-slice CT scanning with dental planning software in diagnosing and treating the impacted teeth. Methods 256-slice spiral CT scanning was performed in 20 cases with im- pacted teeth in jaw bone. By using dental planning software the reconstruction of panoramic structures was conducted, and the exact localization of the impacted teeth in jaw bone was determined. Results A total of 27 impacted teeth were detec- ted in 20 patients. The tooth shape, location and its relationship with the neighboring teeth, including the morphology of tooth crown and root, the direction of impacted teeth eruption and the neighboring anatomy, were clearly displayed in all patients. According to dental planning software analysis, the optimal surgical access was worked ont. Successful extraction of impacted teeth was accomplished in all patients. Conclusion Multi-slice spiral CT scanning with dental planning is an effective and accurate method for precise localization of impacted teeth. It has an important value in guiding the extraction of impacted teeth.
