Coronal and axial high resolution computed tomography of the mandible extends facilities in dentoalveolar surgery. Preoperatively the relationship between the mandibular canal and the roots of deeply displaced third molars can be determined precisely. After surgical removal of lower wisdom teeth iatrogenic defects of the lingual cortical bone can be detected. The additional information obtained when compared with conventional radiographs is demonstrated in case descriptions. Indications for this technique, radiation exposure and implications for surgery are discussed.
下颌骨的冠状位和轴位高分辨率计算机断层扫描扩展了牙槽外科的设备。术前可精确确定下颌管与深度移位的第三磨牙牙根之间的关系。在手术拔除下颌智齿后，可检测到舌侧皮质骨的医源性缺损。通过病例描述展示了与传统X线片相比所获得的额外信息。讨论了该技术的适应证、辐射暴露及对手术的影响。
