In-Vitro Exploration of Silver Nanoparticle Coatings: Novel Insights to Biocompatibility and Antimicrobial Properties

Background: Silver nanoparticle (AgNP) coatings on titanium implants have gained attention for their antimicrobial properties and potential to enhance biocompatibility. This study explored the effects of AgNP coatings on implant integration via in-vitro analysis focused on anti-microbial properties and biocompatibility potential with respect to peri-implant tissue response, and microbial colonization. Methods: A prospective cohort collaborative study was conducted at Baqai Medical University and analyzed by faculty at Shahida Islam Dental College, involving eighty dental implant patients from affiliated tertiary dental Fatima Hospital under #EC-006-22, with a mean age of 54.6 ± 9.1 years. The duration of the study was nine months, from January 2023 to October 2023, using a consecutive sampling technique. The study assessed implant stability, peri-implant inflammation, bacterial adhesion (p. aeruginosa), and bone-implant contact. SPSS version 21 was used for statistical analysis, employing one-way ANOVA (p<0.05) and independent t-tests. Results: AgNP-coated implants demonstrated significantly reduced bacterial adhesion (p = 0.009) and lower peri-implant inflammation markers (p = 0.015) of Interleukin-6 IL-6 and C-reactive proteins CRP compared to uncoated implants with a confidence interval of 95%. P-value <0.05 was considered significant. Improved osseointegration was observed through histological analysis, with enhanced bone-implant contact (p = 0.013). Conclusion: Silver nanoparticle coatings improved both antimicrobial resistance and osseointegration, reducing peri-implant complications. These findings support AgNP coatings as a promising approach for optimizing titanium implant performance in clinical dentistry.
