Octacalcium phosphate is widely used in biomedical applications, particularly in bone regeneration and dental repair. It serves as a precursor to hydroxyapatite, the primary mineral component of bones and teeth, making it valuable in the development of bone graft materials and coatings for dental implants. Its biocompatibility and ability to promote osteoblast activity make it ideal for enhancing bone healing and integration with implants. Additionally, it is utilized in drug delivery systems, where its porous structure allows for the controlled release of therapeutic agents. In research, it is studied for its role in understanding biomineralization processes and developing advanced biomaterials for tissue engineering.
