摘要目的:探讨64排螺旋CT三维重建技术对颌骨内埋伏阻生牙的定位及临床应用价值。方法:对33例临床疑似埋伏阻生牙患者行64排螺旋CT容积扫描,利用GE AW4.4工作站对数据进行多平面重组(MPR)、容积再现技术(VRT)重组图像。结果:33例阻生牙患者中,切牙8颗,侧切牙5颗,尖牙11颗,第三磨牙5颗,多生牙9颗。结论:64排螺旋CT三维重建能准确显示颌骨内埋伏阻生牙及多生牙的数量、位置、形态及萌出方向,为临床提供可靠的指导信息。 Objective To discuss the value of three-dimensional（3D） reconstruction technique of 64-slice spiral CT in the diagnosis of impacted teeth within the jaw bone.Methods Thirty-three suspected cases of impacted teeth were examined by 64 -slice CT volume scan.The acquired data were processed by multi -planar reconstruction（MPR）,volume rendering technique（VRT） using GEAW4.4 workstation.Results Impacted teeth consisted of 8 central incisors,5 lateral incisors,11 canine teeth,5 cranters and 9 accessory teeth were detected from all the 33 patients.Conclusion The 3D reconstruction technique of 64-slice spiral CT could display the details of impacted teeth,including the shape,location and eruption orientation.It can provide valuable information for diagnosis.
