Abstract
The bone has a property called the remodeling to become adaptational change of functional shape depending on load environment. In this study, We made simple model that mimics the cancellous bone with a trabecular structure and build the optimal shape model using growth-strain method. As a result, the top and bottom peripheries in the model were enlarged, and the center periphery was narrow, and the shape provided a result that look like shape of the real bone. In addition, the initial and final lattice bone models were molded by rapid prototyping (RP) device and were compressed. The stiffness on the shape after growth analysis became bigger in comparison with that of initial shape.
