Three-dimensional printing of strontium-containing mesoporous bioactive glass scaffolds for bone regeneration

Bioactive glass-based materials with hierarchical porosity for medical applications: Review of recent advances

“…A significant increase of compressive strength was also observed in 3D-printed strontium-doped MBG scaffolds (8-9 MPa) compared to MBG foams obtained via polyurethane templating (Fig. 4b); an adequate strength was maintained after soaking in simulated body fluid for 7 days, too [91].…”

3D printed porous β-Ca2SiO4scaffolds derived from preceramic resin and their physicochemical and biological properties

“…Generally, 3D porous scaffolds provide more advantages to repair bone defects, because an ideal 3D scaffold with a highly interconnected macroporous structure facilitates cell migration, nutrient delivery, bone ingrowth, and eventually vascularization [24–29]. To date, β-Ca 2 SiO 4 scaffolds were prepared by conventional methods such as polyurethane foam templating [18] and porogen templating [30], which were not easy to control porous scaffolds with well pore interconnection, proper pore size, or high porosity [31,32].…”

Bioactive Glass-Biopolymer Composites for Applications in Tissue Engineering

“…This study also draws attention to the impact of scaffold geometry on macrophage morphology and cytokine secretion profile. Recently, Zhang et al [113] fabricated strontium-containing mesoporous bioactive glass and PVA scaffolds by 3D printing. Results indicated that the scaffolds had uniform interconnected macropores and high porosity.…”
