Developing three-dimensional finite element model of normal human mandible

To build a three-dimensional finite element model of temporomandibular joint and the mandible. Methods: The model was established by using the reconstructive technique of spiral CT in combination with the three-dimensional finite element method. Results: Mechanical changes of various parts of the model in different working conditions could be simulated by means of adding different material properties and boundary conditions. Conclusion: On the basis of conducting spiral CT scan and three-dimensional reconstruction, building a three-dimensional finite element model was possible and satisfactory.
