Summary
Low-pressure oxygen plasma treatment enhanced anodized titanium implants, improving fibroblast adhesion and corrosion resistance. This surface modification shows promise for dental implant applications.
Area of Science:
- Biomaterials Science
- Surface Engineering
- Dental Implantology
Background:
- Implant behavior in soft tissues is influenced by surface properties.
- Anodization improves titanium alloy surfaces, but further enhancement is explored.
- Low-pressure radiofrequency oxygen plasma is a potential surface treatment method.
Purpose of the Study:
- To evaluate the chemical properties and cytocompatibility of anodized titanium alloy surfaces.
- To investigate the effects of additional low-pressure radiofrequency oxygen plasma treatment.
- To assess the impact on corrosion resistance and fibroblast behavior.
Main Methods:
- Titanium alloy (Ti-6Al-4V) discs were anodized at various voltages.
- Half of the anodized samples underwent oxygen plasma treatment (S group).
- Surface characterization (SEM, X-ray, Raman), electrochemical corrosion tests, and in vitro cytotoxicity/fibroblast assays were performed.
Main Results:
- Oxygen concentration slightly increased on plasma-treated surfaces.
- Highest corrosion resistance was found for 78V anodized and plasma-treated samples.
- Plasma treatment significantly enhanced fibroblast proliferation and adhesion without affecting cytotoxicity.
Conclusions:
- Low-pressure radiofrequency oxygen plasma treatment is a promising surface modification for anodized titanium implants.
- This technique improves key properties for transgingival elements.
- The findings support its application in dental implant surface engineering.
