[Bone density change simulation by using internal bone remodeling theory and finite element method].
This paper presents an investigation on the effect of external force on internal bone remodeling by adopting the internal bone remodeling theory in conjunction with finite element method. After the border data are picked from a tomogram, a two-dimensional bone model is formed. The bone remodeling results are obtained by use of the finite element software Ansys. The results agree well with the real structure of bone in some degree, thus demonstrating the validity of the proposed method.
