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 کاملHigh strength bioactive glass-ceramic scaffolds for bone regeneration.
This research work is focused on the preparation of macroporous glass-ceramic scaffolds with high mechanical strength, equivalent with cancellous bone. The scaffolds were prepared using an open-cells polyurethane sponge as a template and glass powders belonging to the system SiO(2)-P(2)O(5)-CaO-MgO-Na(2)O-K(2)O. The glass, named as CEL2, was synthesized by a conventional melting-quenching route...
متن کاملFunctionalized mesoporous bioactive glass scaffolds for enhanced bone tissue regeneration
Mesoporous bioactive glass (MBG), which possesses excellent bioactivity, biocompatibility and osteoconductivity, has played an important role in bone tissue regeneration. However, it is difficult to prepare MBG scaffolds with high compressive strength for applications in bone regeneration; this difficulty has greatly hindered its development and use. To solve this problem, a simple powder proce...
متن کاملEnhanced osteoblastic activity and bone regeneration using surface-modified porous bioactive glass scaffolds.
The potential use as a bone substitute material of a three-dimensional bioactive glass fiber scaffold composed of Na(2)O-K(2)O-MgO-CaO-B(2)O(3)-P(2)O(5)-SiO(2) (BG1) was investigated in this work. Scaffolds were pre-treated with simulated body fluid (SBF) to promote the formation of two different bone-like apatite layers on their surfaces. The topography and roughness of the deposited layers we...
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...
