An in vivo study by the Catholic University of Korea evaluated the effects of vacuum plasma (VP) treatment on SLA titanium implant surfaces using a rabbit femur model.
VP-treated implants demonstrated higher bone volume, bone area ratio (BA), and implant stability quotient (ISQ) compared to untreated controls, although differences were not statistically significant.
The findings suggest that VP treatment may enhance early bone healing and mitigate biological surface aging, contributing to improved long-term osseointegration.
Key Findings:
✅ VP treatment increased surface hydrophilicity and potential cell adhesion.
✅ Bone-to-implant contact (BIC) and bone area (BA) values were slightly higher in the VP group.
✅ ISQ values improved significantly within four weeks.
✅ The VP method offers a gas-free, clinically practical surface activation technique.
Conclusion:
Vacuum plasma treatment shows potential as a non-invasive and efficient technique for rejuvenating implant surfaces and supporting early osseointegration in clinical applications.
