Objective To conotruct bone-implantal distractor complex finite element model rapidly using CAD and finite element analysis software.Methods Alveolar ridge and implantal distractor models were constructed by CAD software.After the models were assembled,all the models were imported into finite element analysis software and converted to 3D finite element models.Result Bone-implantal disrtractor complex model with good quality and no interference was obtained.Conclusion With the integration of CAD and FEA software,complex model with distinctly shape and mechanical representation could be constructed.
