Abstract:

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.

Key words: free-end edentulous, prosthetic, model library, finite element
