Used in biomedical applications such as bone grafts and dental implants due to its similarity to natural bone mineral. Promotes osteointegration and is biocompatible, making it ideal for coating orthopedic implants. Applied in tissue engineering scaffolds to support cell growth and bone regeneration. Also used in chromatography as a stationary phase for protein purification. Found in some toothpaste formulations to reduce sensitivity and repair enamel microdamage.
