ABSTRACT

Objective:

To establish three-dimensional(3D) finite element models of the first mandibular molar restored with three post and core systems.

Methods:

Three 3D finite element models of the restored first mandibular molars were constructed by using CT image reconstruction technique.Then MIMICS software was used to separate the areas and to finish 3D calculation.GEOMAGIC software was applied to modify and generate a NURBS surface in each patch.All components of the models were assembled under the ANSYS preprocessor.Specific materials parameters were selected to simulate the various restoration and dentin status.

Results:

The 3D finite element models of restored first mandible molars were successfully established,which were consistent to the situation observed in the clinical environment.

Conclusion:

It is a practical and accurate method to establish three-dimensional finite element models by CT image reconstruction technique and reverse engineering software MIMICS and GEOMAGIC.
