Modified hydroxyapatite (MHA) is a bioceramic material derived from the primary inorganic component of human bone. It’s been extensively studied and used in various biomedical applications due to its excellent biocompatibility and osteoconductive properties.

Modifications to MHA:

• Doping: The addition of other elements (e.g., zinc, magnesium, strontium) can enhance MHA’s properties, such as antibacterial activity or improved mechanical strength.
• Surface Modification: Surface treatments (e.g., coating with polymers, biomolecules) can improve MHA’s bioactivity and adhesion to surrounding tissues.
• Particle Size and Shape: Controlling the size and shape of MHA particles can influence its mechanical properties and cellular response.
