These applications exploit the fact that calcium sulfate which has been powdered and calcined forms a moldable paste upon hydration and hardens as crystalline calcium sulfate dihydrate. Thermal treatment results in increased crystallinity of this biomimetic apatite layer rendering it more chemically stable, however, with corresponding decreases in the dissolution kinetics and the bioactivity (Faeda et al., 2009b; Queiroz et al., 2013). Assessment of calcium sulfate hemihydrate-Tricalcium silicate composite for bone healing in a rabbit femoral condyle model. For the laser-ablated surfaces, it was observed that following removal torque tests, fractures occurred more often at the bone–bone interface, ie, cohesive failure within interfacial bone, a pattern similar to that described by Brånemark et al. The liquid phase of the apatite cement is made by simply dissolving required chemicals into distilled and sterilized water. Calcium orthophosphates and their solubility product constants. For example, sodium silicate coatings on a laser-ablated surface, while being superior to machined and acid-etched surfaces, both biomechanically (Souza et al., 2013) and histomorphometrically (Souza et al., 2014), showed either similar or marginally lower bone–implant contact and bone area compared to uncoated laser-modified implants. Calcium sulfate hemihydrate whiskers were synthesized successfully via one-step hydrothermal crystallization method using phosphogypsum at 130 °C for 240 min with an initial slurry mass fraction of 2.5wt%.
