Surface Characterization of PEKK Modified by stron-tium –hydroxyapatite coating as implant material Via the magnetron sputtering Deposition technique

Background: The best material for dental implants is polyetherketoneketone (PEKK). However, this substance neither osteoinductive nor osteoconductive, preventing direct bone apposition. Modifying the PEKK with bioactive elements like strontium hydroxyapatite one method to overcome (Sr-HA). Due technique's capacity provide better control over coating's properties, RF magnetron sputtering has been found be a particularly useful technique deposition.
 Materials and methods : With specific conditions, was employed homogeneous thin coating on Polyetherketoneketone substrates.. coatings were characterized by Contact angle, adhesion test, X-ray diffraction (XRD), atomic force microscope Elemental Analysis Energy Dispersive X-Ray (EDX)
 Results indicated that had successfully deposited onto surface significant improvement in wettability value suitable environment cell attachment, spreading, proliferation, differentiation
 Conclusion: Coating can surfaces laying groundwork improving PEKK's potential bioactivity, such as wettability. Wetting qualities are critical implantable materials used predict future osseointegration success.
