The role of oxygen and nitrogen plasma treatments in improving bioactivity and long-term stability of PEO-modified titanium

Key Points

• Bioactivity and long-term stability of PEO-modified titanium significantly improve with oxygen and nitrogen plasma treatments.
• Increased bioactivity was observed after plasma treatments with a 30% enhancement in osteoblast proliferation.
• Assessment using plasma surface treatments shows their potential in biomaterials and implant technology.
• Findings suggest the application of plasma treatments for enhancing titanium surfaces, though further clinical evaluations are needed.
