| 针对目前口腔舌侧正畸中，手术方案的制定以及牙齿移动的预测主要依靠医生经验，缺少定量的数据，可预期效
果差等缺点，提出了舌侧正畸牙齿移动数值计算模型，建立包括牙齿、牙周膜、皮质骨和松质骨的三维有限元模型，模拟
在不同的舌侧正畸力作用下，牙齿整体移动时牙周膜内表面的应变分布，并对牙周膜颈部和根尖部的应变加权值与现有
研究中牙齿移动量的实验数据进行拟合，通过颈部和根尖部的移动来确定牙齿整体的移动，在三维软件中实现对牙齿移
动的过程的模拟，得到移动后的模型作为下一个阶段计算的初始模型。实现了舌侧正畸牙齿移动的动态过程的模拟，该
数值模拟方法可以为舌侧正畸制定方案和预测效果提供参考。 |

| Aiming at the mouth of lingual orthodontics. tooth movement and the development of programs to predict
surgical doctors mainly rely on experience. the lack of quantitative data. defects and poor performance of the excepted
results. this paper put forward lingual orthodontic tooth movement numerical models. including the establishment of
teeth, periodontal ligament, cortical bone. three-dimensional finite element model of cancellous bone. simulated under
different lingual orthodontic force. while overall mobile teeth, periodontal ligament strain distribution surface. and the
periodontal ligament of the neck and strain were weighted values apical tooth movement with the experimental data in the
fitting amount of existing research to determine the overall movement of the teeth to move through the neck and apical
and implementation process of tooth movement in three-dimensional software . the initial model obtained as the next stage
of the calculation model of the moved. The simulation of dynamic process of lingual orthodontic tooth movement was
realized.the numerical simulation method can provide reference for the formulation and prediction of lingual orthodontic
treatment. |
