Chemical Preparation of Beta Calcium Sulfate Hemihydrate Granules with a Special Particle Size as Bone Graft Material
Introduction: Beta calcium sulfate hemihydrate (BCSH), which is commonly known as “Gypsum plaster” has long been used as bone graft material because of its excellent biocompatibility and the ability for bone regeneration. Several methods have been used for the preparation of BCSH, including heat treatment of calcium sulfate dihydrate with water, application of inorganic acids or condensed inorg...
متن کاملA Novel Injectable Magnesium/Calcium Sulfate Hemihydrate Composite Cement for Bone Regeneration
OBJECTIVE . A novel injectable magnesium/calcium sulfate hemihydrate (Mg/CSH) composite with improved properties was reported here. METHODS Composition, setting time, injectability, compressive strength, and bioactivity in simulated body fluid (SBF) of the Mg/CSH composite were evaluated. Furthermore, the cellular responses of canine bone marrow stromal cells (cBMSCs) and bone formation capac...
متن کاملControlled synthesis of monodisperse α-calcium sulfate hemihydrate nanoellipsoids with a porous structure.
We report a facile and green chemical solution approach to synthesize monodisperse α-calcium sulfate hemihydrate (α-HH) nanoellipsoids with a length of 600 nm and a width of 300 nm by simply mixing Ca(2+) and SO4(2-) glycerol-water precursor solutions in the presence of Na2EDTA. The α-HH nanoellipsoid is formed through a Na2EDTA-mediated self-assembly of small primary building blocks (α-HH doma...
متن کاملDevelopment and characterization of an injectable cement of nano calcium-deficient hydroxyapatite/multi(amino acid) copolymer/calcium sulfate hemihydrate for bone repair
A novel injectable bone cement was developed by integration of nano calcium-deficient hydroxyapatite/multi(amino acid) copolymer (n-CDHA/MAC) and calcium sulfate hemihydrate (CSH; CaSO4 · 1/2H2O). The structure, setting time, and compressive strength of the cement were investigated. The results showed that the cement with a liquid to powder ratio of 0.8 mL/g exhibited good injectability and app...
متن کاملA novel injectable and degradable calcium phosphate/calcium sulfate bone cement
The aim of this study was to obtain a composite material which not only has suitable workability but also has excellent degradability. A novel injectable and degradable bone cement consisting of a mixture of calcium phosphate (α-tricalcium phosphate; α-TCP) and calcium sulfate dihydrate (CaSO4. 2H2O; CSD) powders as the solid phase and an aqueous solution containing 2.5 weight percent of Na2HPO...
