One of the important parameters for bone regeneration scaffolds is their mechanical properties, which is the subject of this study in terms of a calcium magnesium silicate, namely bredigite. In this regard, bredigite powders were synthesized by a sol-gel process and then porous bredigite scaffolds were prepared using a polymer sponge method. Sintered bredigite scaffolds were afterwards coated with poly(lactic-co-glycolic acid) (PLGA), and the influence of the PLGA coating on the morphology, porosity and mechanical properties of the bredigite scaffold was investigated. The results showed that the PLGA-coated bredigite scaffolds maintained their porosity size and level required for bone tissue engineering. Typically, the compressive strength of the bredigite/PLGA scaffold was significantly improved compared to the pure bredigite scaffold due to the alteration of porosity.
