摘要
目的:寻求上颌切牙三维有限元模型构建中多材料属性设定的方法,并探讨相关的生物力学意义。方法:通过Mimics软件导入DICOM数据,建立上颌切牙的三维有限元模型,采用CT值与骨密度和弹性模量的经验公式,最终确定模型的材料属性。结果:通过计算,得到了牙齿不同部位的弹性模量,从而实现了对牙齿多材料属性的设定。结论:通过计算模型密度和弹性模量,进一步确定单元材料属性,对于建立接近实际的牙齿三维有限元模型具有重要的意义。
Objective To find a way to set multi-material properties of 3D Finite Element Model of an maxillary incisor,and to discuss biological meanings.Methods An incisor 3D finite element model was established by DICOM data imported by mimics,then CT value and bone density experimental formula were used to confirm the model＇s properties.Results After calculation,modulus of elasticity of different parts of an incisor was gained,and multi-material properties of an incisor were set.Conclusion Multi-material properties of 3D finite element model of an incisor are realized by computing model density and modulus of elasticity,which is helpful to establish a more actual 3D Finite Element Method of the maxillary incisor.
