正畸治疗不仅使不规则的牙齿移位,而且还引起周围骨组织的反应。骨重建被认为是由机械负荷触发的调节机制。本研究旨在探讨正畸负荷对牙齿移动和邻近骨密度分布的影响。一套计算算法,将外部和内部的重塑机制,实施到患者特定的三维有限元(FE)模型,调查和分析正畸治疗下的四种典型模式的正畸负载。正畸治疗的结果是通过使用这种FE为基础的技术数值再现。结果表明,不同的正畸加载方式会导致不同的牙齿移动幅度和特定的骨密度分布形态。它是照明,新开发的算法可以复制临床情况更密切地与以前提出的方法相比。
Orthodontic treatments not only displace irregular teeth but also induce responses in surrounding bone tissues. Bone remodelling is regarded as the regulatory mechanism triggered by mechanical loading. This study was aimed at investigating the effect of orthodontic loading on both tooth movement and neighbouring bone density distribution. A set of computational algorithms incorporating both external and internal remodelling mechanisms was implemented into a patient-specific 3D finite element (FE) model to investigate and analyse orthodontic treatment under four typical modes of orthodontic loading. The consequence of orthodontic treatment was reproduced numerically by using this FE-based technique. The results indicated that the diverse modes of orthodontic loading would result in different magnitudes of tooth movement and particular morphology of bone density distribution. It is illuminated that the newly developed algorithms may replicate the clinical situation more closely compared with the previous proposed method.
