Establishment of finite element models for dentition defect using modular and parametric models

目的建立下颌双侧末端游离缺失修复方案的有限元模型库。方法将模块化建模与参数化建模相结合,利用HyperMesh 7.0、UG 5.0、Abaqus 6.5软件,建立下颌双侧末端游离缺失(765567)及其不同修复设计方案的三维有限元模型。结果获得有限元模型导入Abaqus 6.5软件,可直接运行,无任何信息丢失现象;模型临床几何相似性良好。结论成功建立下颌双侧末端游离缺失及其修复方案的三维有限元模型库,建模过程快速高效,进一步细化了口腔组织模块化建模库。

Objective To establish the three-dimensional finite element model libraries for mandibular bilateral distal-extension prosthesis. Methods Models for bilateral mandibular free-end edentulous （765 567） and parametric prosthetic models were combined to establish the three-dimensional finite element model libraries by means of HyperMesh 7.0,UG 5.0 and Abaqus 6.5 softwares. Results The established finite element model libraries worked well with Abaqus 6.5 software,with no information loss. The models had satisfactory geometric configuration. Conclusion The three-dimensional finite element model libraries for bilateral mandibular free-end edentulous and mandibular bilateral distal-extension prosthesis have been rapidly established.
