Objective: To evaluate a finite element method (FEM) for analysis of the cranial-facial morphology.
Methods: The two-dimensional finite element analysis system was established and used to analysis the lateral side morphology of the soft tissue by the change of each finite unit of the soft tissue in a X-ray cranial-facial lateral cepholometrics film.
Results: The finite element analysis system was showing very well in the figures and data made by the system.
Conclusion: Finite element analysis system may be a good supplement of the traditional X-ray cephalometrics to the soft tissue of orthognatics.
