Study on optimal orthodontic force and quantification of movement of tooth in the alveolar bone remodeling rate

为了确定最佳的正畸力，研究了力的大小和牙齿的运动。力最终在半定量水平上确定。骨小梁骨密度与牙齿运动有统计学意义。然后利用微CT图像构建三维有限元模型。由于牙齿运动后牙槽骨形态测量评估的复杂性，制作有限元模型并不容易。这项研究目前正在进行中。

In order to determine the optimum orthodontic force, force magnitude and the tooth movement were investigated. The forces were finally determined on a semiquantitative level. Then statistically significant correlation between trabecular bone density and tooth movement was found. Subsequently 3D finite element model were constructed from micro CT images. Because of the complexity of alveolar bone morphometric evaluation after the tooth movement, it is not easy to make the finite element models. The study is now in process.
