Widely used in biomedical applications, especially in bone and dental implants due to its strong biocompatibility and ability to integrate with natural bone tissue. Commonly applied as a coating on metallic implants to enhance osseointegration, promoting faster healing and stronger bonding between the implant and bone. Used in bone grafting materials to support regeneration in orthopedic and maxillofacial surgeries. Also found in dental pastes and treatments designed to repair enamel and reduce sensitivity by mimicking the natural mineral structure of teeth. Applied in drug delivery systems where its porous structure allows for controlled release of therapeutic agents. Used in chromatography as a stationary phase for protein purification, leveraging its ionic interaction properties.
