论文摘要
先前关于正畸治疗中牙齿运动的计算模型的研究仅限于单个模型，并且在将模拟结果推广到其他患者方面失败。为此，我们考虑了多个患者，并专注于在相同的载荷和边界条件下进行牙齿运动的变化，以进行治疗室内和患者间分析。我们介绍了一种基于有限元模型（FEM）的新型计算分析工具，该工具介绍了如何评估不同患者的下颌牙齿的初始牙齿位移，以用于不受控制的小费场景，其载荷幅度不同，将其应用于下颌牙列。这是通过将每个患者牙齿的运动建模为负载和牙齿大小的非线性功能来完成的。由于牙齿的尺寸会影响所得的牙齿位移，因此认为从牙齿解剖结构（即冠状高度和根体积）获得的两个临床生物标志物的组合被认为是可以推广到不同患者和牙齿的建议模型。
Previous studies on computational modeling of tooth movement in orthodontic treatments are limited to a single model and fail in generalizing the simulation results to other patients. To this end, we consider multiple patients and focus on tooth movement variations under the identical load and boundary conditions both for intra- and inter-patient analyses. We introduce a novel computational analysis tool based on finite element models (FEMs) addressing how to assess initial tooth displacement in the mandibular dentition across different patients for uncontrolled tipping scenarios with different load magnitudes applied to the mandibular dentition. This is done by modeling the movement of each patient's tooth as a nonlinear function of both load and tooth size. As the size of tooth can affect the resulting tooth displacement, a combination of two clinical biomarkers obtained from the tooth anatomy, i.e., crown height and root volume, is considered to make the proposed model generalizable to different patients and teeth.
