三维有限元法分析下颌骨生物力学的研究进展

Three-dimensional finite element analysis of the mandible

下颌骨是颌面部下1/3唯一能活动的骨骼,在颅面部骨骼中体积最大、面积最广,位置最突出,极易受到各种力量的作用,研究其力学性能显得十分重要。因此,阐明下颌骨承受负载后,其内部应力分布、传递情况,一直是口腔临床医师及研究者们关注的热点。本文从三维有限元建模、生物力学特性及应力分布情况对下颌骨进行分析,为临床研究工作提供参考。

Mandible is the only mobile bone in the lower third of the face, which is the largest, the most wide and prominent in the maxillofacial region. Moreover, it is easily affected by various of forces. Clarifying the stress distribution and transmission after loading is very important and attracting more and more attentions from both clinicians and researchers. In this paper, the mandible was analyzed by three-dimensional finite element modeling, with regard to the biomechanical properties, stress distribution which can provide a reference for clinical research.
