本研究使用了一个二维有限元网格的较低的第一前磨牙模型两个不同的牙齿加载系统，测量无论是垂直或水平位移的这个特定的牙齿。在有限元模型中改变牙周膜的弹性模量，直到模型的水平和垂直位移与两个实验系统相关。结果发现，50 MPa的弹性模量给出了良好的相关性之间的有限元模型和实验系统。(C)1997年爱思唯尔科学有限公司。All rights reserved.
This study used a two-dimensional finite element mesh of a lower first premolar to model two different tooth loading systems which measured either the vertical or the horizontal displacements of this particular tooth. The elastic modulus of the periodontal ligament was varied in the finite element model until the horizontal and vertical displacements of the model correlated with the two experimental systems. It was found that an elastic modulus of 50 MPa gave good correlation between the finite element model and the experimental systems. (C) 1997 Elsevier Science Limited. All rights reserved.
