hydroksüapatiidi

Hydroksüapatiidi is the calcium phosphate mineral component of bone and teeth. Its chemical formula is Ca5(PO4)3(OH). In its pure form, it is a white crystalline solid. Hydroksüapatiidi is the most abundant mineral in mammalian hard tissues, providing structural integrity and strength. It forms a highly ordered crystalline structure that is resilient to mechanical stress.

The formation of hydroksüapatiidi, known as biomineralization, is a complex process involving the deposition of calcium and phosphate ions. This process is tightly regulated by biological factors to ensure the proper formation and organization of bone and enamel. Hydroksüapatiidi's surface is reactive, allowing it to bind to various ions and molecules, which plays a role in its biological functions.

Beyond its natural occurrence, synthetic hydroksüapatiidi has found significant applications in biomaterials. Due to its biocompatibility and bioactivity, it is widely used in orthopedic implants, dental prosthetics, and bone graft materials. Its ability to integrate with living bone tissue makes it an ideal choice for enhancing bone regeneration and repair. Hydroksüapatiidi coatings on metallic implants, for instance, can promote osseointegration, the direct bonding of bone to the implant surface. Its use in dentistry also extends to toothpaste formulations aimed at remineralizing tooth enamel.
