Hydroksüapatiidis

Hydroksüapatiidis is the Estonian name for hydroxyapatite. It is a mineral form of the apatite group with the formula Ca5(PO4)3(OH). Hydroxyapatite is a naturally occurring crystalline mineral that is the primary component of tooth enamel and bone. It is composed of calcium, phosphate, and hydroxide ions. In biological systems, hydroxyapatite plays a crucial role in providing structural integrity and hardness to bones and teeth. It can be found in various forms, including synthetic and natural. Synthetic hydroxyapatite is widely used in biomedical applications, such as bone grafts, dental implants, and coatings for orthopedic implants. Its biocompatibility and ability to integrate with natural bone tissue make it a valuable material in regenerative medicine. The chemical structure of hydroxyapatite allows for ion exchange, which can be utilized in applications like water purification and chromatography. Its presence in the Earth's crust, though less common than in biological contexts, also contributes to geological formations.
