Bioceramics due to their unique features and compatibility with physiological environment of the body are very important and have One of tissue engineering.One of tissue engineering approaches is the use of high-porosity engineering materials called sacaffolds.The challenge facing the engineers is the complexity of the properties required for the ideal scaffolding.Calcium silicate bioceramics are a group of bioceramics that are biologically active and bind to bone and soft tissue, including biceramics called wollastonite, which have high bioactivity and biocompatibility, but due to the high biodegradability and low strength alone are not used in the body. Research has shown that by doping elements such as zinc, sodium, copper, zirconium and magnesium in wollastonite, it can be somewhat suitable for mechanical properties and control the degradation rate.Research also has shown that magnesium is beneficial to the body due to its key role in bone nutrition and mineral metabolism, and is useful for the elimination of wollastonite defects.Another group of bioceramics is magnesium silicate bioceramics that have good mechanical properties and are biocompatible.One of these bioceramics is forsterite, which is bio-compatible with the body, has higher mechanical properties than wollastonite, and is nano-scale bioactive.Therefore, it is expected that the magnesium / forsterite doped wollastonite composite scaffold would be more suitable for mechanical and biological properties.In this study, forsterite, wollastonite and doped wollastonite doped with 6.8 and 10% M magnesium by sol-gel method and composite wollastonite / forsterite and magnesium doped wollastonite / forsterite with polymer sponges methods to fill the bone defects were synthesized.For this purpose, wollastonite -magnesium synthesized powder with different ratios of 10, 15 and 20 wt% forsterite was prepared as slurry.After adding polyvinyl alcohol, the sponges were applied to the slurry and then sintering at 1250 ° C for 3 hours.The specimens were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) morphology and their inter-phase combinations were investigated and analyzed by an elemental analysis of the X-ray energy (EDX) of their chemical composition it placed. The bioactivity of the samples was evaluated by placing in the simulated body fluid (SBF) and by Fourier-transform infrared spectroscopy (FTIR).The cell adhesion test was also performed to evaluate the biocompatibility of the scaffolds.The degradability rate of the samples was investigated by Tris buffer and it was determined that with increasing magnesium content, the weight loss rate was lower.The compressive strength results also showed that the strength increased significantly with increasing magnesium and forsterite percentage.Also, the results of bioactivity tests confirmed the formation of Apatite layer on the surface of the samples.The results of cell adhesion test also showed biocompatibility and the ability to form cell on the surface of the scaffolds.Ultimately, the doped wollastonite composite scaffold with 10% M magnesium / forsterite exhibited more suitable mechanical and biological properties for in-body applications than wollastonite. This composite scaffold can be a good option for bone tissue engineering applications.
