Peltier et al. As can be seen in Fig. Sato et al. For the putty type, a lower liquid to powder mixing ratio is used whereas a larger liquid to powder mixing ratio is recommended for injection from a syringe or tube since more liquid results in a softer paste. The utilization process comprises mixing the calcium sulfate hemihydrate with water to form a pourable slurry. Crystal structure of gypsum is monoclinic and its lattice parameters are shown in Table 2 (Ballirano and Caminiti, 2001; Atoji and Rundle, 1958; Cole and Lancucki, 1974; Pederson and Semmingsen, 1982). 75, 940–948. Moreover, the removal torque values for HAp coated, laser-ablated implants were markedly higher than both the uncoated, laser-ablated implants and the uncoated, machined implants (Faeda et al., 2009a). To achieve this aim, strontium-substituted calcium sulfate hemihydrate (Sr-CSH) and hydroxyapatite (HA) were mixed to develop a novel composite. Ruhaimi (2001) reported that the application of calcium sulfate to newly distructed bone in the mandible of rabbit increased the rate of osteogenesis and calcification. Sulfate compounds are salts or esters of sulfuric acid formed by replacing one or both of the hydrogen atoms with a metal. Articles of calcium sulfate hemihydrate … Calcium orthophosphates and their solubility product constants. As shown, there is complete resorption of the beads and bone repair is completed. Research and sample quantities and hygroscopic, oxidizing or other air sensitive materials may be packaged under argon or vacuum.

However, calcium phosphate powders react partially with each other even without mixing liquid phases. Also, Fig. In other words, calcium orthophosphates are listed from acidic to alkaline salts. © 1997-2021 American Elements. The mechanical interdigitation of mineralised tissue with topologically complex surfaces, as well as the physicochemical interaction of bone tissue with a thicker surface oxide layer, greatly improves the biomechanical anchorage. Recent work on the precipitation of the mineral gypsum ( calcium sulfate dihydrate) has shown that contrary to long-standing opinion, this phase can precipitate from solution at room temperature via a bassanite (calcium sulfate hemihydrate, or plaster of Paris) intermediate phase. In other words, powder with large diameter, i.e. By continuing you agree to the use of cookies. 9.14) produced by soaking in SBF (Faeda et al., 2009a). As can be seen in these tables, some salts that are not calcium phosphates are also used. As described earlier, laser ablation results in the development of a thick TiO2 layer that attracts Ca2+ and PO43− ions to the surface, resulting in the formation of a relatively unstable calcium phosphate coating of poor crystallinity. Japan's largest platform for academic e-journals: J-STAGE is a full text database for reviewed academic papers published by Japanese societies Toggle navigation Therefore, both calcium and phosphate ions have to be supplied simultaneously for the precipitation of apatite or brushite.
