Titanium implants have been utilised for their biocompatibility and mechanical strength; yet, problems such as peri‑implant infections and inadequate bone integration may undermine their efficacy. Coating titanium implants with iron nanoparticles (FeNp) has surfaced as a promising approach to improve osseointegration and antibacterial characteristics. FeNp's distinctive capacity to react to magnetic fields and produce reactive oxygen species (ROS) has the potential to enhance implant results.</p><p><strong>Objective: </strong>To assess the influence of FeNp-coated titanium implants on osseointegration, mechanical stability, osteogenesis, and antibacterial effectiveness against prevalent implant-associated infections, Staphylococcus aureus and Escherichia coli.</p><p><strong>Materials and methods: </strong>In vivo investigations were performed on animal models to evaluate implant stability by resonance frequency analysis (RFA) and removal torque measurements at 6 and 12 weeks post-implantation.

Removal torque values were also significantly higher in GROUP B at 12 weeks (76.30 ± 14.20) compared to GROUP A (46.10 ± 9.25), suggesting enhanced mechanical integration (p < 0.01).

The findings indicate that FeNp coatings might substantially enhance implant longevity and diminish the likelihood of infection, offering a potential approach for clinical applications, especially for patients at elevated risk of implant failure.
