It is widely accepted that the initial interactions between the cells and implant surface are crucial to clinical success. One of the promising alternative materials for tissue engineering is polyetheretherketone (PEEK) which has good chemical resistance and mechanical properties similar to those of human bones . However, its hydrophobic and chemically inert surface limits local bone attachment . Consequently, there have been efforts to enhance PEEK bone-implant integration by incorporating molecules (such as HA) or making it porous . Regarding to the latest, this study aims to demonstrate a process that can greatly enhance the density and interconnectivity of a PEEK porous product (US2012323339) . Moreover, a novel surface modification through wet-chemistry protocol has been developed for RGD and OGP (osteogenic growth peptide) grafting onto porous PEEK scaffolds (US2013172273) . As a result, the production of porous structures manufactured by thermally induced phase ...
