On the Choice of the Architecture of Osteoconductive Bioceramic Implants

Resumo

An a priori approach for the analysis of the architecture of osteoconductive bioceramic implants has been proposed. The most permeable products have been achieved in the case of the Kelvin architecture and the gyroid. The promising implant architecture is chosen to be the Kelvin model with a porosity of 70% and the pore sizes of 750 μm. The permeability of this architecture calculated to be 987 darcy for water approaches the value of trabecular bone tissue. It is found that the most rigid model among the architectures studied is the model with diamond architecture, while the most compliant are the Kelvin model and gyroid.
