Abstract: The valence electron structures and electron densities on some lattice planes of biomaterials Ti-6Al-4V and Au-Pd-Pt were calculated by using bond length difference method of the empirical electron theory of solids and molecules. The results show that there exist the planes with continuous densities in the three crystal cells involved, which verified to some extent the validity of“Atomic Boundary Condition”applying in biomaterials research. It was proposed that the sufficient understanding and reasonable modeling on microstructure of living body are necessary to evaluate directly the electron density continuity between biomaterial and living tissue.
