mandibular second molar

progress in research in c-shaped root canal of mandibular second molar

下颌第二磨牙C形根管的研究进展

objective to investigate the displacements and the stress distributions of a mandibular second molar.

目的了解下颌第二恒磨牙不同载荷下近中移动时的位移及应力分布情况。

Generating the FEM model: We pick out one probably intact extracted mandibular second molar as the specimen tooth, whose crown length, width and height are close to the normal mean value of the named same teeth.

有限元模型的建立：选择1颗较完整的下颌第二磨牙作为标本牙，其牙冠的长、宽、高以及冠根比例接近正常均值。
