摘要
目的 :探讨MSCT颌骨薄层扫描技术在牙种植术前检查与评估中的应用价值。方法 :应用GE 8排螺旋CT对牙种植术前预带定位模板的颌骨做螺旋 1.2 5mm层厚连续扫描 ,通过相应的牙科专用软件 (Dentascan)对扫描数据进行多平面重建 ,同时采用三维 ( 3D)立体重建技术观察牙种植术前颌骨全景结构形态、骨质密度和上颌窦、鼻腔底、鼻腭管以及下颌管等重要结构。结果 :Dentascan软件及 3D技术能够清晰显示种植区域颌骨的外部形态及内部重要结构 ,并能利用其图像上的标尺测量工具精确测量种植区的骨高度及宽度。结论
Objective:To investigate the application of MSCT in preoperative assessment of panoramic structures of jaw for dental implantation by lamella scans technique.Methods:MSCT with dentascan software had generated multiplanar reconstructions on coronal, sagittal and axial sections. The lamella scans technique included 1.25mm slice continuous scanning and the location of template beforehand. These techniques could demonstrate jaw shape, structure and bone quality, integration of dental implant with bone, and relation of dental implant with important structures in jaw. Results:Dentascan software and the three dimensional techniques can clearly display the appearance and internal important constructions of jaw in implantation area, and measure the height and width of the jaws. Conclusion:MSCT scan designs can provide important informations for the dentists who will operate dental implantation.
