Key Advantages
Biocompatibility & Osteoconductivity
Hydroxyapatite is highly biocompatible, meaning it is well-tolerated by the body, and osteoconductive, actively promoting new bone tissue formation.
Enhanced Bioactivity
Through techniques like ion substitution (e.g., with Mg2+, Sr2+, Zn2+), the bioactivity of hydroxyapatite can be significantly improved, leading to better cellular responses.
Tailored Material Properties
Calcination and specific ion doping allow for fine-tuning the material's properties, such as surface area and ion release, making it suitable for diverse applications.
Key Applications
Dental Care
Used in toothpaste for enamel remineralization, dentin hypersensitivity reduction, and cavity prevention, offering a natural alternative to fluoride.
Bone Tissue Engineering
Serves as a scaffold material and coating for implants, facilitating bone regeneration by supporting osteoblast activity and cell proliferation.
Biomaterial Coatings
Applied as coatings on medical implants to improve their integration with bone tissue and enhance overall performance and longevity.
