Among the recent and important causes are the longevity of the population and the number of accident traumas. Regenerative medicine is part of the science in biomaterial engineering that addresses the replacement or regeneration of bone tissue. One of the most important materials is bone cement, given the function of joining and providing the phase transition to obtain adequate physical and biological results for the different applications in dentistry and orthopedics. The brushite cements can be synthesized from the wollastonite reaction, presenting osteoconductive, biocompatible, osteoblastic cells, for cell proliferation and differentiation. Thus, the objective of this study was to develop a bone cement with different concentrations of brushite phase from the synthesis of wollastonite with orthophosphoric acid, by the dissolution-precipitation method, evaluating their properties. The samples of the bone cements were characterized by X-ray diffraction, presenting corresponding crystalline phases with the proposed study. The scanning electron microscopy obtained morphology of particles in the form of needles and irregularities with more round shapes. We can highlight that the bone cement obtained presented fundamental characteristics, having the potential to be applied as biomaterial in the biomedical area.
