Twenty-nine human cadaver mandibles were dissected longitudinally and cross-sectionally for determination of the precise location of the inferior alveolar nerve, artery, and vein. The neurovascular bundle was located in contact with, or very close to, the lingual cortical plate until it reached the mental foramen. Anterior to the mental foramen, the neurovascular bundle was not a distinct entity and was located close to the labial cortical plate. In the body of the mandible, the neurovascular bundle was located about one centimeter above the mandibular inferior border. The distance from the lateral border of the neurovascular bundle to the external surface of the buccal plate was usually half a centimeter in the molar and premolar regions. The mandibular canal was usually formed by a thin bony plate that, grossly, had more of an appearance of trabecular bone; in only a few mandibles was there a thin layer of cortical bone.
对29具人类尸体下颌骨进行纵向和横断面解剖，以确定下牙槽神经、动脉和静脉的精确位置。神经血管束在到达颏孔之前一直与舌侧皮质板接触或非常靠近舌侧皮质板。在颏孔前方，神经血管束不是一个独立的结构，而是靠近唇侧皮质板。在下颌骨体部，神经血管束位于下颌下缘上方约1厘米处。在磨牙和前磨牙区域，神经血管束外侧缘到颊板外表面的距离通常为半厘米。下颌管通常由一层薄骨板形成，大体上更像是小梁骨的外观；只有少数下颌骨有一层薄的皮质骨。
