摘要
目的:采用有限元的方法建立上颌磨牙根管系统的三维有限元模型。方法:采用Micro-CT扫描,应用Mimics8.1、Geomagic studio8、Unigraphics NX及Ansys9.0等逆向工程软件分别得到上颌第一磨牙根管系统三维外形、实体模型和有限元模型。结果:重建了根管系统的三维有限元模型,网格质量好,具有高度的精确度,并由此证实模型的可行性。结论:将Micro-CT扫描技术、数字图像处理技术与有限元方法结合起来,建立出高精度的上颌第一磨牙根管系统的三维有限元模型,为口腔生物力学提供了研究手段。
AIM： To construct a three -dimensional （3D）finite element model of the maxillary first molar root system and provide a digital model for analysing the biomechanical properties of the molar. METHODS ： Micro - CT scanning technology was used in combination with medical images reconstruction software and RE（ reverse engineering） software. Dependability of the model was testified. RESULTS： An ideal three- dimensional finite element model of the maxillary first molar root systerm in vitro was constructed, which can provid a basis for the future research of its biomechanical characteristics. CONCLUSION： The constructed 3 - DFE of the maxillary first molar root system in vitro model was feasible and effective and could be applied in the stress analysis of denture and teeth.
