Hydroksiapatitin

Hydroksiapatitin is a naturally occurring mineral form of calcium apatite with the formula Ca5(PO4)3(OH)2. It is a significant component of vertebrate bones and teeth, where it forms the inorganic matrix. In these biological structures, hydroksiapatitin provides hardness and rigidity. Its crystal structure is hexagonal.

Beyond its biological role, hydroksiapatitin has numerous applications. In dentistry, it is used in toothpaste formulations to remineralize tooth enamel and prevent cavities. It is also employed in dental implants and bone grafting materials due to its biocompatibility and ability to integrate with bone tissue. In medicine, it is a key component in prosthetic materials and drug delivery systems.

Hydroksiapatitin can be synthesized in laboratories for various purposes. Its chemical properties, such as its ability to bind to certain molecules, make it useful in chromatography for separating proteins and other biomolecules. The synthetic forms can be tailored in terms of particle size and surface properties to optimize their performance in specific applications. Its presence in biological systems and its synthetic versatility make hydroksiapatitin a compound of considerable scientific and industrial interest.
