CONSTRUCTION OF 3-D FINITE ELEMENT MODEL USING COMPUTER

目的 :探讨在有限元模型建立过程中 ,运用计算机模拟口腔软硬组织建立有限元模型的可行性。方法 :用CT扫描、ANSYS和PRO E等软件相结合方法在下颌骨有限元模型上直接模拟粘骨膜等软组织 ,建立三维有限元模型。结果 :建立了仅存留下颌两侧尖牙的下颌骨及软组织三维有限元模型。结论 :运用CT扫描与CAD软件结合方法模拟口腔软组织建立有限元模型 ,方法简单可行 。

Objective:To study the methods of using computer to simulate oral soft tissues in 3 D finite element model construction.Methods:AUTOCAD,ANSYS and PRO E software were applied to simulate mandible and periosteum.Results:3 D finite element model with two canines and soft tissue in mandible was constructed.Conclusion:The method of combining CT scanning and CAD software to simulate soft oral tissue is simple to perform and can be applied for the study of the oral biomechanics.
