Paragraph starter

This systematic review by Fosca et al. (2023) demonstrates that ion-doped calcium phosphate coatings offer significant antibacterial advantages for orthopaedic and dental implants. By incorporating ions such as silver or zinc, these coatings can actively inhibit bacterial growth, thereby reducing the risk of implant-associated infections and promoting better osseointegration. This suggests that for design projects focused on implantable devices, the strategic use of antimicrobial surface treatments like ion-doped CP coatings is a critical consideration for enhancing patient safety and treatment success.
