n. 下颌骨
The lower jaw is called the mandible or mandibular bone.
下颌关节被称为下颌或下颌骨。
The opposite mandibular bone without implants served as a control group.
对侧下颌骨不种植为对照组。
Results: mandibular canal was formed by a thin layer of compact bone in spongy bone of mandibular bone.
结果:下颌管是下颌骨的骨松质内形成较薄的骨密质骨管。
Objective: To observe the difference of mandibular bone density in aged normal and osteoporotic people.
目的:观察老年正常人与老年骨质疏松症患者下颌骨骨密度的差别。
Objective: To inquire into the relationship between the mandibular bone mineral density and vertical craniofacial morphology.
目的:探索不同垂直面型与下颌骨骨密度之间的关系。

下颌骨(Mandibular Bone)是人体颅面骨骼中最大且唯一可活动的骨骼,位于面部下三分之一,构成下颌的主要结构。它由水平位的“下颌体”和垂直位的“下颌支”组成,并通过颞下颌关节与颅骨的颞骨相连,实现咀嚼、说话等功能。
下颌骨易受外伤性骨折(如跌倒或撞击)、感染(如骨髓炎)及肿瘤(如骨肉瘤)影响。先天性畸形如小颌畸形也可能导致功能障碍。
口腔修复、正颌手术及骨折固定均需精准评估下颌骨形态。现代影像学(如CBCT)可三维重建其结构,辅助诊疗。
