|
| The calcium ions in saliva are liable to form calcium hydroxyapatite crystals, the mineral form of calcium used for the formation of tartar. |
|
| Only thereafter can it interact with the mineral phase of the tooth, which is a carbonated and calcium deficient hydroxyapatite. |
|
| This element is also present in the bones and nervous tissues as hydroxyapatite. |
|
| It is deposited in bone in the form of a mineral complex called hydroxyapatite, which confers strength to the skeleton. |
|
| Previous studies show that osteoblasts show better proliferation activity on merwinite than on hydroxyapatite. |
|
| Ossein, which is essentially a biological hydroxyapatite, was found to improve the modulus and increase the hydrophilicity of the polymeric substrate. |
|
| A porous orbital implant structure for implantation into the orbital cavity of a mammal comprising pores having a mean size of less than 200 micrometers wherein said structure comprises hydroxyapatite. |
|
| When first deposited, mineral is crystallographically amorphous, but with maturation it becomes typical of the apatite minerals, the major component being hydroxyapatite. |
|
| The primary distinction is between hydroxyapatites synthesized from calcium and phosphate on one hand and hydroxyapatite of allogenic or xenogenic origin on the other. |
|
|
|
| It is then infused with calcium, oxygen and phosphorous in a series of chemical steps, to create a hydroxyapatite scaffold with the same structure as the original wood. |
|
| Osteoid consists mostly of a fibrous protein called collagen, while the mineral complexes are made up of crystals of calcium and phosphate, known as hydroxyapatite, that are embedded in the osteoid. |
|
| The lower viability of the cells on bovine hydroxyapatite seen here may have been caused by the morphological changes observed on the SEM micrographs. |
|
| The TCP component confers a capacity for absorption while the hydroxyapatite prevents too rapid remodeling, thus supporting the restoration and preservation of bone volume during the healing process. |
|
| Clodronate disodium forms complexes with the hydroxyapatite of bone, altering the crystalline structure in such a way that dissolution of the crystals is inhibited. |
|
| The mechanical stability of the augmentate volume is maintained, because of the slow resorption rate of hydroxyapatite preventing excessive resorption. |
|
| Tumanov, Solid solution formation at the sintering of hydroxyapatite fluorapatite ceramics. |
|
| Among them hydroxyapatite is most commonly used in stomatology and orthopaedics for bone replacement and regeneration. |
|
| In our research, we succeeded in the synthesis of sulfonic acid supported on a bed of magnetic nanoparticles coated by hydroxyapatite. |
|
| Calcinosis cutis is the deposition of amorphous calcium hydroxyapatite, forming subcutaneous nodules. |
|
| The accepted theory is that the trauma results in a hydroxyapatite or calcium pyrophosphate dihydrate crystal deposition. |
|
| A nanocomposite coating has been produced in this research by combining hydroxyapatite nanoparticles as the base material and diopside ceramic. |
|
| When surgery is performed, repair of the resulting defect can sometimes be accomplished with hydroxyapatite cement. |
|
| The collagen fibers give bone its tensile strength, and the interspersed crystals of hydroxyapatite give bone its compressive strength. |
|
| Around the strands calcium and phosphate precipitate on the surface of these strands, within a days to weeks becoming crystals of hydroxyapatite. |
|
| Dinesh Katti and graduate student Avinash Ambre includes a novel method that uses nanosized clays to make scaffolds to mineralize bone minerals such as hydroxyapatite. |
|
| Other portions of the conical molecules encouraged hydroxyapatite crystal formation on the fibers, while yet other parts were designed to attract various cells in the body. |
|
| The total-etch system completely removes the smear layer using an acidic gel and demineralizes hydroxyapatite under the smear layer of the dentin. |
|
| The powerful combination of stabilised chlorine dioxide, fluoride and hydroxyapatite creates the optimal environment for strong, healthy teeth and remineralisation. |

| Mild, Efficient biomimetic synthesis of rodlike hydroxyapatite particles with a high aspect ratio using polyvinylpyrrolidone as capping agent, Cryst. |
|
|
|
| Hydroxyapatite is biocompatible and bioactive, and is used to coat stainless steel and titanium implants because it bonds to bone and forms indistinguishable unions. |
