In VitroEvaluation of Bioactivity of Chemically Deposited Hydroxyapatite on Polyether Ether Ketone [PDF]

International Journal of Biomaterials, 2015
Polyether ether ketone (PEEK) is considered the best alternative material for titanium for spinal fusion cage implants due to its low elasticity modulus and radiolucent property. The main problem of PEEK is its bioinert properties. Coating with hydroxyapatite (HA) showed very good improvement in bioactivity of the PEEK implants.
