 This review provides an overview of the current state of the art in ion-doped calcium phosphate, CP, based coatings for orthopedic and dental implant applications. It examines how the addition of ions can affect the physical, mechanical, and biological properties of these coatings, as well as the potential benefits of combining them with other components such as antibiotics. Finally, it discusses the effectiveness of these coatings against certain types of bacteria. This article was authored by Marco Fosca, Alexandra Strezza, Julian V. Antoniak, and others.
