成人颅面复合体三维有限元模型的建立

Abstract

Abstract: Objective To construct a threedimensional finite element model of adult craniofacial complex for the further investigation of the feasibility of palatal implant anchorage for RME in adults and the comparative study between the toothborne RME and the boneborne one.Methods Spiral CT was used to scan adult craniofacial complex,and the computer image processing and transcription technique and ANSYS were employed to establish the three dimensional finite element model.〗Results A three dimensional finite element model was successfully constructed,which had great geometrical characters and biomechanical similarity.Conclusions This model precisely reconstructed cortical and cancellous bone as what they really are,which is suitable for biomechanical analysis of RME.

Key words: spiral CT scan, craniofacial complex, three dimensional finite element model, RME 
