Effects of sintering temperature on surface morphology/microstructure, in vitro degradability, mineralization and osteoblast response to magnesium phosphate as biomedical material

Abstract: Magnesium phosphate (MP) was fabricated using a chemical precipitation method, and the biological performances of MP sintered at different temperatures as a biomedical material was investigated. The results indicated that the densification and crystallinity of MP increased as the sintering temperature increased. As the sintering temperature increased, the degradability of MP in PBS decreased, and the mineralization ability in SBF significantly increased. In addition, the MP sintered at 800 °C (MP8) possessed t… Show more

“…Osteoconduction is a process highly dependent on the conditions provided by the materials used in bone tissue engineering and driven by the process of cell proliferation, mediated or not by the incorporation of bioactive elements [5]. While the osteoconductive properties of the elements present in the membranes used in the present study are recognized [39], the differences of components of the mineralization process provides evidence of desirable performance in the regenerative process [40][41][42], which is related to the irradiated membranes and probably to the related microstructural changes [43]. In general, modulation of regenerative responses and osteoconduction can be achieved by subjecting materials to radiation exposures of different nature [35], the susceptibility to the generation of structural changes will depend on the characteristics of the material and the radiation source which establishes an area of research that deserves further attention.…”

“…By inducing the formation of apatite on the surface of a biomaterial in contact with relevant biological fluids like SBF, it becomes possible to gain deeper understating of its in vitro bioactivity and its potential to promote bone regeneration or establish interfacial bonding with bone tissue in-vivo [25]. The process of bone growth, where calcium and phosphate are deposited on the bone matrix, plays a crucial role in determining the bone ability to form and develop.…”
