人腭板软组织三维有限元模型的建立

Establishment of a soft tissue 3-dimension finite element model of human palate

目的:建立人上颌腭板软组织三维有限元模型。方法:利用ansys软件在原有上颌骨有限元模型的基础上选定腭板口腔侧工作面,结合上颌腭板软组织解剖特征在选定之腭板口腔侧平面上手动提取3.06 mm厚度的黏骨膜组织,并赋予弹性材料属性,从而建立适合生物力学分析的上颌腭板软组织三维有限元模型。结果:本实验应用有限元技术,在计算机上建立了一个能够反映上颌腭板软组织生物力学性能的有限元模型。结论:该模型形态逼真,可用于后续研究。

Objective：To establish a soft tissue 3-dimension（3D）finite element model of human palate.Methods：Based on the intrinsic finite element model of human maxilla,palatal mucoperiosteum flap with the thickness of 3.06 mm was added on the oral side of the plate model by ANSYS software,material property of the soft tissue was loaded,the soft tissue 3D finite element model of the palate was established.Results：By applying finite element method,the established 3D finite element model could reflect biomechani-cal properties of the soft tissue of the palate on computer.Conclusion：The 3D finite element model of the soft tissue of human palate provides the foundation for further study.
