牙齿缺失后下颌骨的形态很少受到详细的关注。改进这一主题的文件将允许更好地解释牙科X光片，并使那些从事牙齿植入，以更好地了解组织的性质，其中假体被放置。在本研究中，对7具解剖室尸体的下颌骨进行了曲面断层摄影，通常可以清楚地显示下颌管，但对切牙管的显示较差。下颌管壁在无牙下颌和无牙下颌中相似，并且高度穿孔，如Cryer（安德森等人，1991年）。无齿症。标本主要由松质骨组成，偶尔有单个骨单位。下颌孔附近的下牙槽神经为粗大的神经干，由3 ~ 4个神经束组成，并有结缔组织鞘。它变得更松散地向颏孔排列。颏孔内侧的神经在髓内多呈小束状。任何切口管是不明确的和神经血管束，当存在时，穿过一个迷宫的小梁间空间。(C)2001 Wiley-Liss，Inc.
The morphology of the mandibular banal after loss of teeth has received little detailed attention. Improved documentation of this topic would allow better interpretation bf dental radiographs and would enable those engaged in tooth implantation to better understand the nature of the tissue into which the prostheses are placed. In this study on mandibles' from seven dissecting room cadavers panoramic radiographs usually showed the mandibular canal clearly, an incisive canal less so. The wall of the mandibular canal was similar in deritate and edentulous mandibles, and was highly perforated, as suggested by Cryer (Anderson et al., 1991). In edentulous. specimens, it was composed mainly of cancellous bone with only occasional single osteons. The inferior alveolar nerve near the mandibular foramen was a large trunk, consisting of three to four nerve bundles with connective tissue sheaths. It became more loosely arranged toward the mental foramen. Medial to the mental foramen, the nerves were frequently in the form of small bundles in the marrow. Any incisive canal was ill-defined and neurovascular bundles, when present, ran through a labyrinth of intertrabecular spaces. (C) 2001 Wiley-Liss, Inc.
