Hydroxyapatite is a calcium phosphate mineral with the chemical formula Ca₁₀(PO₄)₆(OH)₂. It is the primary inorganic constituent of bone and dental enamel.
Hydroxyapatite’s crystalline structure enables it to serve as an osteoconductive material used in bone grafts and implant coatings, supporting the attachment and proliferation of bone cells without causing significant immune response.
