| 摘 要： | 目的探讨多层螺旋CT（MSCT）三维重建在上颌埋伏牙定位中的应用价值。方法对85例埋伏牙患者进行轴位螺旋CT扫描,最大密度投影（MIP）、多层面重建（MPR）及齿科后处理软件获得埋伏牙多方位图像及曲面断层影像。结果在85例患者中均清晰显示埋伏牙,牙齿的形态、结构及与邻牙、神经管的解剖关系。结论 MSCT三维重建技术可以很好的显示牙齿结构,能立体、直观的显示埋伏牙及其与周围结构的关系,在埋伏牙的定位及治疗中有重要的临床意义。

| Abstract: | Objective To explore the role and clinical application of multiple spiral CT（MSCT） three-dimensional reconstruction in the location of pseudoanodontia.Methods 85 cases with pseudoanodontia were scanned by axial spiral CT.Multiple-directional images and surface tomography were obtained with maximum intensity projection（MIP）,multiplanar reconstruction（MPR） and post-processing software.Results Embedded teeth were clearly showed in all 85 cases.Structure,shape of the pseudoanodontia and anatomy with adjacent teeth and submaxilla nerviduct were also clear.Conclusion MSCT post-processing techniques can show good teeth structure,three-dimensional and visual display of teeth and its relationship with surrounding structures.It is important to locate and treat pseudoanodontia. |
