Functionalized 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 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 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...
متن کاملComposite scaffolds of mesoporous bioactive glass and polyamide for bone repair
A bone-implanted porous scaffold of mesoporous bioglass/polyamide composite (m-BPC) was fabricated, and its biological properties were investigated. The results indicate that the m-BPC scaffold contained open and interconnected macropores ranging 400-500 μm, and exhibited a porosity of 76%. The attachment ratio of MG-63 cells on m-BPC was higher than polyamide scaffolds at 4 hours, and the cell...
متن کاملbioactive glass nanopowder for thetreatment of oral bone defects
objective: osseous defects around dental implants are often seen when implants are placed in areas with inadequate alveolar bone, or around failing implants. bone regeneration in these areas using bone grafts or its substitutes may improve dental implants prognosis. the aim of this study was to prepare and characterize the bioactive glass nanopowder and development of its coating for treatment ...
