The chemical reaction responsible for the setting and hardening of calcium sulfate cement is based on the rehydration of CSH: This reaction involving a dissolution–reprecipitation process is slightly exothermic and the resulting bioceramic/cement consists of a network of entangled rod-like CSD (or gypsum) crystals. In vivo, gypsum has been observed to disappear very fast, much faster than brushite cements.31 To decrease the removal rate and improve the biological result, calcium sulfates are generally applied as dense pellets57 or composites with HA granules have been proposed.48, C. Rey, ... D. Grossin, in Comprehensive Biomaterials, 2011, Calcium sulfate hemihydrate (CaSO4⋅ 1/2H2O), known as plaster of Paris, has been used as a building material for at least 5000 years and used by Egyptians to decorate burial tombs of pharaohs.211 Dreesman was the first to report a study on the implantation of plaster of Paris as a bone filler material in eight patients.212 Since this first clinical success, several groups of research have studied different bioactive ceramics for bone filling and repair involving calcium sulfate hemihydrate (CSH) as cement, preset granules, or resorbable composites (CSH-HA or CSH-polymer).213,214. Hydrated inorganic chemical compound with the formula CaSO 4 … In addition, CSH intended for biomedical application must be well characterized and carefully produced. Gypsum appears as white or … has also been investigated as local controlled release system.214–216, In addition to the bioactivity, additional properties of CS have also been pointed out by several authors: CS acts as a barrier membrane in the defect area and allows bone generation during healing as an hemostatic agent, probably due to the release of calcium ions known as a coagulant, and as an angiogenic agent.211, K ISHIKAWA, in Bioceramics and their Clinical Applications, 2008. 2H 2 O) was measured in NaCl and glycerol aqueous solution with the mass fraction of glycerol 0–80% and molality of NaCl 0–6 m in the temperature range of 303.15 to 343.15 K and atmospheric pressure. freely soluble in physiological conditions. Calcium sulfate in food key facts. Calcined gypsum … resulting large specific surface area, dissolves quickly. All forms are white solids that are poorly soluble in water. It is used in manufacturing plasterboard, cement, and fertilizers. The liquid phase plays an important part in the initial hardening reaction, handling property, injectability as well as anti-washout property (Ishikawa et al. With a view to extending and controlling the calcium sulfate-based biomaterial resorption properties, composites of calcium sulfate and poly-l-lactic acid (PLLA) consisting either of a nanocomposite of both constituents or of granules of CS coated with a thin layer of PLLA have been studied by Madmidwar et al.213 The authors showed that the full resorption of a nanocomposite consisting of 4% PLLA and 96% of calcium sulfate occurred after 4 months in vivo. of sodium alginate, calcium sulfate dihydrate, trisodium phosphate 12-hydrate, glycerol, and water was defined by the mass ratio as 1.5:2:1:7.5:50, respectively. Sulfates occur naturally in numerous minerals including gypsum (calcium sulfate dihydrate). Create. Association of this composite or of calcium sulfate cement with biologically active components (growth factors, platelets, antibiotic, etc.) CSH exists in two forms, α and β. A quantitative determination is only possible if the samples are measured in an almost hermetically sealed crucible. Chem. … The liquid phase of the apatite cement is made by simply dissolving required chemicals into distilled and sterilized water.
