  • Introduction: Dental implant has siezed great attention in recent years and bacterial infections are the most common side effects associated with them. In this regards, using specific biomaterials in implant composition may reduce oral cavity infections besides increasing implants stability. It was aimed to review on the biomaterials used in different studies to decrease the potential bacterial infections in various types of dental implants.
  • Methods: We explored the internet in Google Scholar, Pubmed, Pubmed Central and Bing search engines using main key words including dental implant, stability and bacterial infection. All the manuscripts after 2018 were included in the present review.
  • Results: Si3N4 or Silicon nitride based dental implants follwed by silver-doped hydroxyapatite have demonstrated promising effects in antibacterial charactristics of dental implants. In addition, Si3N4 based implants have shown great biocompatibility and biomechanical flexibility compraed to other studied biomaterials.
  • Conclusion: Silicon nitride based dental implants maybe the best alternative to traditional biomaterials used in the composition of dental implants. Further studies are warranted to determine the long-term antibacterial effects and implant stability in different individuals with various background disease and oral cavity chemical composition.
