“…In general, the substitute material should exhibit bioactivity, osteoconductive properties, and appropriate biodegradable properties. Some Ca-(Mg)-silicate bioceramics, such as wollastonite (CaSiO 3 and CSi), 10,11 diopside (CaMgSi 2 O 6 ), 12,13 akermanite (Ca 2 MgSi 2 O 7 ), 14,15 merwinite (Ca 3 MgSi 2 O 8 ), 16,17 and bredigite (Ca 7 Mg(SiO 4 ) 4 ), 18,19 have been widely fabricated as porous scaffolds, granules, or coatings for healing hard tissue. Such silicate-based bioactive ceramics to regenerate bone tissue can speed up the bone healing time, prevent implant rejection, and even improve vascularization.…”

“…For instance, the fabrication of a diopside scaffold using two spacers of different shape and size led to different porosities and compressive strengths. [ 49 ] On the other hand, increased compaction pressure led to an increase in compressive strength, which is due to its effects on decreasing the sizes and numbers of micropores. [ 49,50 ]…”

How Does Scaffold Porosity Conduct Bone Tissue Regeneration?

Despite progresses in tissue healing, repairing large bone defects remains an unmet challenge. Tissue engineering (TE) using porous scaffolds offers great promise in providing solutions by which bone healing can be increased, and the need for further surgical intervention can be reduced. Nonetheless, the successful performance of a porous scaffold depends on key structural factors including porosity, pore size, geometry, and interconnectivity. Herein, recent advancements on this topic are reviewed and the effects of fabrication methods on making potential scaffolds for advanced bone regeneration are discussed.The upward trend of population aging, increased numbers of accidents, sport injuries, trauma, and bone tumor resection are increasing the demand for substitutes to regenerate and/or repair damaged skeletal and dental bones. [1] Bone tissue poses a simple yet highly organized ultracomposition in which each portion plays a pivotal role in moderating the elasticity and strength of the bone. [2] The intrinsically dynamic bone tissue structure allows the restoration of damaged parts via the self-healing process. [3] This remodeling process is dependent on the dynamic equilibrium between the bone-forming (osteoblast) and bone-resorbing cells (osteoclast) during mechanical stimulation. [4] Nevertheless, this healing process is not sufficient for repairing massive and critical bone defects; thus, there is a need for drastic healing accelerators and substitutive or supportive therapeutics. [5] Specially, the regenerating of large bone defects is a serious and challenging clinical issue. To address the issue, different types of bone graft substitutes such as autografts, allografts, and xenografts are used. [6] These grafts, however, come with certain drawbacks, including donor site morbidity and limited supply. Moreover, aged persons cannot provide rich bone tissue for their own tissue replacement due to osteoporosis. [7] To address the limitations associated with natural bone-derived substitutes, biomaterials have been developed during recent decades. [8] Engineering biomaterials made it possible to simulate the bone microenvironment and construct programmable scaffolds for purposeful therapeutic procedures. Bioactive ceramic materials are favorable for bone tissue engineering (BTE) due to their resemblance to the mineral phase of bone, and direct bonding with host bone tissue without the formation of fibrous tissue. In addition, the variety in the chemical composition of bioceramics, particularly silicate-based ceramics (SiCa), can contribute to adjustments in mechanical properties, bioactivity, and biodegradability.A fundamental constituent of engineering tissue is the scaffold, which acts as the structural template providing a suitable substrate for cell proliferation, differentiation, and attachment resulting in new tissue formation. In tissue engineering (TE), the scaffold serves as the structural guide and the substrate for cell anchorage. The scaffold also contributes to the remodeling of the extracellular mat...
