Surface oxynitriding dependence on apatite formation on biomedical titanium metal in a simulated body fluid
Biomedical titanium metals subjected to gas under precisely regulated oxygen partial pressures (PO2) from 10 to 10 Pa at 973 K for 1 hour were soaked in a simulated body fluid (SBF), whose ion concentrations were nearly equal to those of human blood plasma, at 36.5 C for up to 7 days. After soaking in SBF, the following relationship held: The growth rate of apatite decreased in the order PO2 of...
متن کاملFluoride-containing bioactive glasses: effect of glass design and structure on degradation, pH and apatite formation in simulated body fluid.
Bioactive glasses are able to bond to bone through formation of carbonated hydroxyapatite in body fluids, and fluoride-releasing bioactive glasses are of interest for both orthopaedic and, in particular, dental applications for caries inhibition. Melt-derived glasses in the system SiO(2)-P(2)O(5)-CaO-Na(2)O with increasing amounts of CaF(2) were prepared by keeping network connectivity and the ...
متن کاملFormation and characteristics of the apatite layer on plasma-sprayed hydroxyapatite coatings in simulated body fluid.
Plasma-sprayed hydroxyapatite (HA) coatings were incubated in simulated body fluids (SBFs) for different periods of time to investigate the nucleation and growth of apatite on their surface. The layer that formed was recognized as having similarities to bone apatite because it is poorly crystallized, non-stoichiometric or calcium deficient, and contains carbonate and magnesium. Scanning electro...
متن کاملApatite-forming ability of bioactive poly(l-lactic acid)/grafted silica nanocomposites in simulated body fluid.
Bioactive PLLA/surface-grafted silica (g-SiO₂) nanocomposite scaffolds were fabricated by solid-liquid phase separation method. And solid PLLA/g-SiO₂ nanocomposite films were prepared by solution casting method. A series of parallel tube-like morphology and internal ladder-like structure of PLLA/g-SiO₂ nanocomposite scaffolds were observed by SEM. The formation of bone-like apatite in the simul...
متن کاملA Study of Bone-Like Apatite Formation on β-TCP/PLLA Scaffold in Static and Dynamic Simulated Body Fluid
The ability of apatite to form on the surface of biomaterials in simulated body fluid (SBF) has been widely used to predict the bone-bonding ability of bioceramic and bioceramic/polymer composites in vivo. Porous β-tricalcium phosphate/poly(L-lactic acid) (β-TCP/PLLA) composite scaffold was synthesized by new method. The ability of inducing calcium phosphate (Ca-P) formation was compared in sta...
