Abstract:

Objective To explore a new method to construct the three- dimensional finite element model of microimplant- maxilla using Materialise′s interactive medical image control system（Mimics）. Methods The maxilla with all teeth was scanned with Spiral CT and the images were transferred into the Mimics 9.0 software to obtain the threedimensional images. The Abaqus 6.5 software was used to mesh the three- dimensional model and to establish the finite element model. Results A detachable three- dimensional finite element model of micro- implant- maxilla based on Mimics was constructed rapidly, which can be flexibly re- assembled. Conclusion The method of constructing the three- dimensional finite element model of micro- implant- maxilla is available and effective. The geometrical analogy of the model was greatly improved by using the Mimics system.
