Robocasting and surface functionalization with highly bioactive glass of ZrO 2 scaffolds for load bearing applications

Fracture behaviors of ceramic tissue scaffolds for load bearing applications

Healing large bone defects, especially in weight-bearing locations, remains a challenge using available synthetic ceramic scaffolds. Manufactured as a scaffold using 3D printing technology, Sr-HT-Gahnite at high porosity (66%) had demonstrated significantly improved compressive strength (53 ± 9 MPa) and toughness. Nevertheless, the main concern of ceramic scaffolds in general remains to be thei...

Bioactive 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...

Bioactive 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...

Highly porous bioresorbable scaffolds with controlled release of bioactive agents for tissue-regeneration applications.

Highly porous poly(DL-lactic-co-glycolic acid) films with controlled release of horseradish peroxidase (HRP) as a model protein have been successfully developed and studied. These films, which are prepared by freeze-drying inverted emulsions, are designed for use in tissue-regeneration applications. The effects of the emulsion's formulation and host polymer's characteristics on the film's micro...
