Purpose:
To establish a three dimensional finite element model of a maxillary impacted canine and its support tissues by means of finite element method (FEM) and spiral CT which can offer digital model for orthodontic traction.
Methods:
A patient with a completely bony impacted maxillary canine was chosen. The CAD model of the canine and its surrounding tissues was established using spiral CT equipment, Mimics and Unigraphic. The CAD model was changed to FEM models by MSC. Mentat which could cut nets in CAD models.
Results:
With the use of spiral CT,Mimics,UG and MSC, FEM model of the maxillary impacted canine and its support tissues and the whole maxilla was constructed and the model was of high geometrical similarity.
Conclusion:
The FEM model of maxillary impacted canine established by spiral CT,Mimics,UG and MSC has high accuracy, integrated constitution and optimized mesh which can be taken into account in the course of the treatment planning prior to starting therapy.
