Abstract |
Despite the high biocompatibility and clinical effectiveness of Ti-based implants, surface
functionalization (with complex osteointegrative/antibacterial strategies) is still required. To enhance
the dental implant surface and to provide additional osteoinductive and antibacterial properties,
plasma electrolytic oxidation of a pure Ti was performed using a nitrilotriacetic acid (NTA)-based Ag
nanoparticles (AgNP)-loaded calcium–phosphate solution. Chemical and structural properties of
the surface-modified titanium were assessed using scanning electron microscopy (SEM) with energy
dispersive X-ray (EDX) and contact angle measurement. A bacterial adhesion test and cell culture
biocompatibility with collagen production were performed to evaluate biological effectiveness of
the Ti after the plasma electrolytic process. The NTA-based calcium–phosphate solution with Ag
nanoparticles (AgNPs) can provide formation of a thick, porous plasma electrolytic oxidation (PEO)
layer enriched in silver oxide. Voltage elevation leads to increased porosity and a hydrophilic nature
of the newly formed ceramic coating. The silver-enriched PEO layer exhibits an effective antibacterial
effect with high biocompatibility and increased collagen production that could be an effective complex
strategy for dental and orthopedic implant development. |
