What is synthetic hydroxyapatite?
Synthetic hydroxyapatite (HA, general formula Ca10(PO4)6(OH)2) is a material commonly used in biomaterial engineering and regenerative medicine for bones [1], [2]. It displays high biocompatibility with biological apatite, the main component of the mineral fraction of bones and dental tissues.
How hydroxyapatite is formed?
Hydroxyapatite is a naturally occurring mineral of biological and agricultural importance. Human and animal bones are composed of hydroxyapatite. In nutrient recovery processes, hydroxyapatite is generated through treatment of waste streams containing calcium.
What is the chemical formula for hydroxyapatite?
Hydroxyapatite is a natural mineral form of calcium apatite, the chemical formula Ca5 (PO4) 3 (OH), but it is usually written Ca10 (PO4) 6 (OH) 2 to indicate that the crystal unit cell of two entities.
What do you mean by hydroxyapatite?
Hydroxyapatite is a calcium phosphate mineral contained in normal bone. The lattice-like structure of hydroxyapatite crystals accounts for the rigidity of bones.
What is the function of hydroxyapatite?
Hydroxyapatite: A major component and an essential ingredient of normal bone and teeth. Hydroxyapatite makes up bone mineral and the matrix of teeth. It is hydroxyapatite that gives bones and teeth their rigidity. Hydroxyapatite molecules can group together (crystalize) to form microscopic clumps.
What is Milwaukee shoulder?
Milwaukee shoulder syndrome (MSS) is a rare destructive, calcium phosphate crystalline arthropathy. It encompasses an effusion that is noninflammatory with numerous aggregates of calcium hydroxyapatite crystals in the synovial fluid, associated with rotator cuff defects.
What is ceramic hydroxyapatite?
CHT ceramic hydroxyapatite is a spherical, macroporous form of hydroxyapatite. The ceramic material retains the unique separation properties of crystalline hydroxyapatite, but can be used reproducibly for many cycles at high flow rates and in large columns.
What is the formula for calcium apatite hydroxyapatite?
Scanning electron microscope picture from University of Tartu. Hydroxyapatite, also called hydroxylapatite ( HA ), is a naturally occurring mineral form of calcium apatite with the formula Ca 5 (PO 4) 3 (OH), but it is usually written Ca 10 (PO 4) 6 (OH) 2 to denote that the crystal unit cell comprises two entities.
What are the defects of hydroxyapatite bone apatite?
Synthetic hydroxyapatite bone apatite. This resemblance is remodelling of healthy bone. bone defects caused by trauma or disease. These include: inorganic drug delivery entity. mechanical strength need to be tailored accordingly. Consequently, much research
Can a synthetic apatite be synthesized from a biological one?
Biological apatite varies in composition (it contains additional ions that play a key biological role in the development and mineralization of bone) and crystallinity. Synthetic HA can be synthesized using a range of synthesis methods that include wet-chemical and solid-state methods.
Which is the wet chemical method for hydroxyapatite?
Wet-chemical synthesis methods include sol–gel methodology, coprecipitation, emulsion technology, and batch and continuous hydrothermal synthesis. HA has been the focus of significant research and development due to its similarity to biological apatite.
