Bone tissue has complex structure and biological system. The history of bone remodeling theory experiences three main periods: qualitative analysis, quantitative analysis and fix quantify value simulation by computer. Nowadays, there are two common bone remodeling models based on mechanical approach and phenomenological approach respectively. The mechanical model has the same basis that the apparent density is designed as a direct response to a certain mechanical stimulus. Otherwise, the phenomenological model is largely dependent on Basic Multicellular Units (BMU) damage and porosity change. Most of remodeling methods are isotropic, which does not denote constitutive relation of bone microstructure. This paper has reviewed bone remodeling criteria in Numerical Simulation.
