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。 The mandible is the only one-third of the maxilla under the active bones in the craniofacial bones in the largest volume, the most extensive area, the most prominent position, vulnerable to a variety of forces, the study of its mechanical properties is very important. Therefore, to clarify the mandibular load, the internal stress distribution, transmission, has been the oral clinicians and researchers are concerned about the hot spots. This paper analyzes the mandible from three-dimensional finite element modeling, biomechanical properties and stress distribution, providing reference for clinical research.
