N2 - In recent years, much attention has been paid to tissue engineering for bone regeneration. In current orthopedic treatments, artificial bone substitutes composed of bioactive ceramics are sometimes used instead of autografts and allografts to obtain bone tissue ingrowth in damaged regions. In this study, the fracture mechanism of nonab-sorbable porous hydroxyapatite was assessed using 3D finite element analysis (FEA). 3D finite element (FE) models were constructed using µ-CT images of porous hydroxyapatite. Computational analysis was conducted under compressive loading. The elements of both tensile and compressive fracture increased as the value of the compressive load increased. This study showed the potential for applying the computational method to evaluating the time-dependent fracture process of porous bioceramics.
