Polyether–ether–ketone (PEEK) is a commonly employed biomaterial for spinal, cranial, and dental implant applications due to its mechanical properties, bio-stability, radiolucency, especially when compared metal alloys. However, biologically inert behavior poses substantial challenge in osseointegration between host bone PEEK implants, resulting loosening. Previous studies identified surface modification methods that prove beneficial enhancing stability supporting cell growth, but simultaneously, those modifications have the potential promote bacterial attachment. In this study, sandblasting sputter coating are performed address aforementioned issues as preclinical work. The aim investigate effects of roughness through alumina platinum (Pt) sputtered on friction, viability, adhesion rates material. This study reveals higher average sample (the highest was 1.2 μm obtained after sandblasting) increases coefficient which 0.25 untreated 0.14, indicating better performance also increased adhesion. A novelty method Pt seen significantly reduce by 67% sandblasted 24 h immersion, implying biocompatibility without changing viability performance.
