摘要:

近些年来有限元分析法已经成为正畸材料开发和研制的重要研究手段之一。在口腔正畸生物力学中,三维有限元主要应用于牙齿及颌骨在矫治力作用下瞬间转动中心位置的研究,矫治力作用下牙周组织应力的研究,矫治器力学性能的分析,口颌系统功能的研究,生长发育研究。本文对三维有限元在正畸领域的研究进行概述。

Abstract:

In recent years， 3D finite element analysis has become an important research method in orthodontic materials research and development. In orthodontic biomechanics, this method is mainly used in the research of instantaneous rotation center position of the teeth and jaw under orthodontic force, the research of the stress of periodontal tissues under the corrective force, the analysis of orthodontic appliance's mechanical property, the research of the Stomatognathic's function, the research of growth and development. This paper is an overview of 3D finite element analysis' application in orthodontics.
