| Still, the idea that hydroxyapatite in buried bone undergoes gradual change to fluorapatite is a correct one. |
| The calcium ions in saliva are liable to form calcium hydroxyapatite crystals, the mineral form of calcium used for the formation of tartar. |
| It is deposited in bone in the form of a mineral complex called hydroxyapatite, which confers strength to the skeleton. |
| These compounds are incorporated into hydroxyapatite crystals that are deposited in an osteoid matrix during new bone formation. |
| In view of the elastic modulus of hydroxyapatite being at least three orders of magnitude larger than that of collagen, this seems to be quite natural. |
| For a durable anchoring in the bone, the plasma spray method is used to deposit a hydroxyapatite coating on the corundum-blasted surface. |
