Optimizing the Processing of Porous Melt-Derived Bioactive Glass Scaffolds
We were able to produce the first ever meltderived bioactive glass scaffold that met the requirement of an ideal bone scaffold by using the gel-cast foaming process and a new glass composition. However, initially a small fraction of sodium potassium sulfate crystals formed during processing. The purpose of this work was to study and prohibit the growth of those crystals, which was the result of...
متن کاملMelt-derived bioactive glass scaffolds produced by a gel-cast foaming technique.
Porous melt-derived bioactive glass scaffolds with interconnected pore networks suitable for bone regeneration were produced without the glass crystallizing. ICIE 16 (49.46% SiO(2), 36.27% CaO, 6.6% Na(2)O, 1.07% P(2)O(5) and 6.6% K(2)O, in mol.%) was used as it is a composition designed not to crystallize during sintering. Glass powder was made into porous scaffolds by using the gel-cast foami...
متن کاملBioactive Glass Scaffolds for Bone Tissue Engineering
In materials science, the ability to develop porous constructs with high mechanical strength is important for a broad range of emerging applications, including filters, catalyst support, and tissue engineering scaffolds. Particularly for orthopedic surgery, the regeneration of large bone defects in load-bearing limbs remains a challenging problem that require scaffolds that combine the strength...
متن کاملPorous and strong bioactive glass (13-93) scaffolds prepared by unidirectional freezing of camphene-based suspensions.
Scaffolds of 13-93 bioactive glass (6Na(2)O, 12K(2)O, 5MgO, 20CaO, 4P(2)O(5), 53SiO(2); wt.%) with an oriented pore architecture were formed by unidirectional freezing of camphene-based suspensions, followed by thermal annealing of the frozen constructs to grow the camphene crystals. After sublimation of the camphene, the constructs were sintered (1 h at 700°C) to produce a dense glass phase wi...
متن کاملBioactive Glass and Glass-Ceramic Scaffolds for Bone Tissue Engineering
Traditionally, bioactive glasses have been used to fill and restore bone defects. More recently, this category of biomaterials has become an emerging research field for bone tissue engineering applications. Here, we review and discuss current knowledge on porous bone tissue engineering scaffolds on the basis of melt-derived bioactive silicate glass compositions and relevant composite structures...
