摘　　要：医学影像技术是正畸治疗术前常用的检查手段。根尖片、咬合片、曲面断层片及普通二维CT均有助于埋伏牙的诊断,而CT三维重建技术则可以提供埋伏牙在颌骨中的具体位置、大小、形态、唇腭侧的深度、与周围结构的关系等详细信息。结合二维X线技术和CT三维重建技术可以为埋伏牙的确诊提供更可靠的依据,确定合理的正畸治疗方案。Medical imaging technique is commonly used prior to operative orthodontic treatment. Periapical film, bite film, panoramic radiograph and 2DCT can help diagnose impacted teeth. With the help of 3D reconstruction by CT technique, the location, magnitude, shape, three-dimensional space and adjoining relation of impacted teeth can be determined. Combination of the 2D X-ray technique and 3D CT reconstruction technique can provide reliable evidence for the diagnosis of impacted teeth and for a rational plan of orthodontic treatment.
