The effect of -tricalcium phosphate additive on the alumina matrix was investigated. The sintering behaviour of the alumina tricalcium phosphate composites was characterized by using magic angle spinning nuclear magnetic resonance, X-ray diffraction, dilatometry, differential thermal analysis and scanning electron microscopy analysis. The mechanical properties of composites have been investiga...

introduction : osteon® is an alloplastic material containing 70% hydroxyapatite and 30% β-tcp. calcitonin, a hormone produced by the thyroid gland, not only prevents bone resorption by reducing both the number and the activity of osteoclasts, but also stimulates bone formation. considering the favorable effects of calcitonin on bone formation, we hypothesized that the addition of calcitonin to ...

background: bone tissue engineering requires materials that are biocompatible, mechanically suited for bone function, integrated with the host skeleton, and support osteoinduction of the implanted cells for new bone formation. the aim of this study was to compare the osteogenic potential of xenograft with hydroxyapatite/β- tricalcium phosphate (ha/β-tcp) scaffold. methods: new zealand rabbits (...

tricalcium phosphate as hydroxyapatite is used as a suspension stabilizer in styrene polymerization process. particle size of tcp plays an essential role in the particles’ size distribution and geometrical form of polystyrene products. as the particle size of tcp is reduced, there will be much better chance to engulf the styrene particles. the higher the number of tcp particles surrounding each...

PURPOSE To evaluate the regenerative potential of a fully synthesized homogenous hydroxyapatite:β-tricalcium phosphate 60:40 alloplast material in sinus lift procedures. MATERIALS AND METHODS Hydroxyapatite:β-tricalcium phosphate was used for sinus floor augmentation. After 9 months, 12 biopsies were taken from 12 patients. Routine histologic processing was performed and specimens were analyz...

The aim of this study was to examine the bone regeneration properties of beta-tricalcium phosphate hydrothermally converted from foraminifera carbonate exoskeleton in the repair of rat calvarial defect. These natural materials possess unique interconnected porous network with uniform pore size distribution, which can be potentially advantageous. In total, 20 adult male Wistar rats received full...

Phosphate solubilizing bacteria (PSB) possessing the ability to solubilize insoluble inorganic phosphates were isolated from rhizosphere soil. Eighty-one potential PSBs thus obtained were quantitatively screened for phosphate solubilization. Of these, four bacteria found to be efficient phosphate solubilizers, were selected for further evaluation, and found that they solubilize tricalcium phosp...
