n. 下颌骨
The lower jaw is called the mandible or mandibular bone.
下颌關節被稱為下颌或下颌骨。
The opposite mandibular bone without implants served as a control group.
對側下颌骨不種植為對照組。
Results: mandibular canal was formed by a thin layer of compact bone in spongy bone of mandibular bone.
結果:下颌管是下颌骨的骨松質内形成較薄的骨密質骨管。
Objective: To observe the difference of mandibular bone density in aged normal and osteoporotic people.
目的:觀察老年正常人與老年骨質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:探索不同垂直面型與下颌骨骨密度之間的關系。

下颌骨(Mandibular Bone)是人體顱面骨骼中最大且唯一可活動的骨骼,位于面部下三分之一,構成下颌的主要結構。它由水平位的“下颌體”和垂直位的“下颌支”組成,并通過颞下颌關節與顱骨的颞骨相連,實現咀嚼、說話等功能。
下颌骨易受外傷性骨折(如跌倒或撞擊)、感染(如骨髓炎)及腫瘤(如骨肉瘤)影響。先天性畸形如小颌畸形也可能導緻功能障礙。
口腔修複、正颌手術及骨折固定均需精準評估下颌骨形态。現代影像學(如CBCT)可三維重建其結構,輔助診療。
