基于螺旋CT影像的计算机辅助定位阻生牙的临床应用研究

Clinical application of computer assisted technology based spiral CT scan for locating impacted tooth

目的探讨计算机辅助技术定位埋伏阻生牙的临床应用价值。方法利用螺旋CT对35例颌骨埋伏阻生牙患者进行颌骨扫描,将DICOM数据输入Simplant软件,通过对颌骨数据后处理定位埋伏阻生牙。结果通过Sim-plant软件的处理,埋伏阻生牙的三维形态、生长方向、颊舌向和近远中向的位置以及与邻牙和周围解剖结构的关系均得到了清晰显示。结论计算机辅助技术可以精确定位埋伏阻生牙,为制定临床治疗方案提供依据。

Objective To evaluate clinical value of computer assisted technology for locating the impacted tooth. Methods Thirty-five patients with impacted tooth were received spiral CT scan. The DICOM data were processed by Simplant software for locating the impacted tooth. Results The reconstruction images clearly showed detail of the impacted teeth, including 3D surface image, eruption orientation, buccal and lingual location, medial and distal location and relationship with dentition and circumambient anatomic structure. Conclusion The computer assisted technology can localize the impacted tooth precisely and provide valuable information for clinical treatment.
