Up to 50% by volume and 70% by weight of human bone is a modified form of hydroxyapatite, known as bone mineral. [7] Carbonated calcium-deficient hydroxyapatite is the main mineral of which dental enamel and dentin are composed. Hydroxyapatite crystals are also found in pathological calcifications such as those found in breast tumors, [8] as ...
Microcrystalline hydroxyapatite and ossein-hydroxyapatite are forms of calcium phosphate used as a dietary supplement. [36] Bone meal as a calcium supplementation has largely been discontinued due to concerns of contamination with heavy metals such as lead, arsenic, mercury, and cadmium identified in the 1980s.
The two major components of bone are hydroxyapatite [Ca10(PO4)6(OH)2], and collagen fibers. Hydroxyapatite, which is one of the most stable forms of calcium phosphate, makes up about 60 to 65 percent of the bone. [5] The rest of the bone is composed of materials including chondroitin sulfate, keratan sulfate and lipid. [5]
Bone Mineral Density (BMD) tends to peak at a young age. When children are younger, they start building up their BMD through their nutrition and through exercise. BMD peaks at around 12.5 years old for girls and around 14 years old for boys. [23] It could be caused by a deficiency in calcium or Vitamin D. Calcium is the main nutrient for bone ...
This chemical structure affords a high affinity for calcium hydroxyapatite, allowing for rapid and specific skeletal targeting. Bisphosphonates are a class of drugs that prevent the loss of bone density, used to treat osteoporosis and similar diseases. They are the most commonly prescribed drugs used to treat osteoporosis. [1]
The mineral in bone (known as bone mineral) is hydroxyapatite with a lot of carbonate ions, while the organic portion is made mostly of collagen and some other proteins. The hierarchical structural of bone spans across to a three tiered hierarchy of the collagen molecule itself. [ 14 ]
Since the elastic modulus values of ceramic materials are generally higher than that of the surrounding bone tissue, the implant can cause mechanical stresses at the bone interface. [10] Calcium phosphates usually found in bioceramics include hydroxyapatite (HAP) Ca 10 (PO 4) 6 (OH) 2; tricalcium phosphate β (β TCP): Ca 3 (PO 4) 2; and ...
Coral based xenografts are mainly calcium carbonate (and an important proportion of fluorides, useful in the context of grafting to promote bone development) while natural human bone is made of hydroxyapatite along with calcium phosphate and carbonate: the coral material is thus either transformed industrially into hydroxyapatite through a ...
