【摘要】 采用ProspeedⅡ型螺旋CT对25例种植牙患者行术前扫描,将获得的数据信息进行多平面图像重建及术前分析设计,术后再次扫描和图像重建,分析种植术后效果;所有病例重建图均能清晰显示颌骨形态、质地和重要解剖结构,如颏孔、上颌窦、下牙槽神经管,并能精确的测量缺牙区可用骨的高度、厚度和宽度;利用CT技术辅助临床种植牙手术及术后评估有重要的临床意义。更多还原

【Abstract】 ProspeedⅡspiral CT was used in 25 cases to obtain 3-D image data for dental implantation in molar area before and after treatment.The images of all 25 cases could clearly display the morphology of jaw bones and the accurate structure,such as mental foramen,maxillary sinus,mandibular alveolar nerve tube,height and width of alveolar ridge.The spiral CT is beneficial in dental implantation.更多还原
