Abstract: The bone has the ability to adapt to an altered mechanical environment. Through the analysis of the bone remodelling and based on the engineering strength design criteria, a mechanism of the bone remodelling with consideration of the load characteristics is proposed. The effect of the load characteristics on the mechanical stimulus is discussed and the bone formation of the alveolar bone in the area under a tensile stress and the bone resorption in the area under a pressure are analyzed and simulated. It is shown that the mechanism of bone remodelling with consideration of the load characteristics is reasonable and it can improve the mechanism of bone remodelling.
