چکیده
Low-temperature ceramics based on magnesium calcium phosphate cement are a promising resorbable material for bone tissue restoration with the possibility of functionalization. The replacement Mg2+ ion Ca2+ at stage preparation precursor leads to production multiphase containing phases brushite, monetite, and newberyite, different dissolution rates. Multiphase volumetric resorption preservation their geometric shape, which was confirmed by results an evaluation output ions into contact solution X-ray density ceramic samples during subcutaneous implantation. combined introduction sodium pyrophosphate decahydrate citric acid monohydrate as setting inhibitors neutralizes insignificant negative effect physico-chemical properties (strength, pH, porosity), determining optimal composition. In vivo experiments in composition showed biological response, affecting rate par ions. Preliminary data biocompatibility solubility determined magnesium-calcium additives that regulate be potential vector further research, including orthotopic implantation models.

متن کاملLow temperature method for the production of calcium phosphate fillers
BACKGROUND Calcium phosphate manufactured samples, prepared with hydroxyapatite, are used as either spacers or fillers in orthopedic surgery, but these implants have never been used under conditions of mechanical stress. Similar conditions also apply with cements. Many authors have postulated that cements are a useful substitute material when implanted in vivo. The aim of this research is to de...
متن کاملLong-term cell-mediated protein release from calcium phosphate ceramics.
Efficient delivery of growth factors from carrier biomaterials depends critically on the release kinetics of the proteins that constitute the carrier. Immobilizing growth factors to calcium phosphate ceramics has been attempted by direct adsorption and usually resulted in a rapid and passive release of the superficially adherent proteins. The insufficient retention of growth factors limited the...

متن کاملSynthetic calcium phosphate ceramics for treatment of bone fractures.
Bone is a complex natural material with outstanding mechanical properties and remarkable self-healing capabilities. The mechanical strength is achieved by a complex structure of a mineral part comprising apatitic calcium phosphate crystals embedded in an organic matrix. Bone also contains several types of cells constantly replacing mature bone with new bone. These cells are able to seal fractur...
