BACKGROUND The aim of this study was to evaluate the interaction of bioactive and biodegradable poly (lactide-co-glycolide)/bioactive glass/hydroxyapatite (PBGHA) and poly (lactide-co-glycolide)/bioactive glass (PBG) nanocomposite coatings with bone. MATERIALS AND METHODS Sol-gel derived 58S bioactive glass nanoparticles, 50/50 wt% poly (lactic acid)/poly (glycolic acid) and hydroxyapatite na...

Introduction: Bioactive glass (BAG) is increasingly used in dentistry, aiming to provide superior mechanical properties, optimal chemical stability, and favorable antimicrobial activity the oral environment. This study aimed measure flexural strength (FS) of resin-modified ionomer (RMGI) cement containing 58S nano-BAG. Materials Methods: In this vitro study, 0wt (Weight) %, 10wt%, 20wt%, 30wt% ...

Electrospun organic/inorganic hybrid scaffolds have been appealing in tissue regeneration owing to the integrated physicochemical and biological performances. However, conventional electrospun with non-woven structures usually failed enable deep cell infiltration due densely stacked layers among fibers. Herein, through self-assembly-driven electrospinning, a polyhydroxybutyrate/poly(ε-caprolact...

The aim of the present study was to prepare and characterize bioglass-natural biopolymer based composite scaffold and evaluate its bone regeneration ability. Bioactive glass nanoparticles (58S) in the size range of 20-30 nm were synthesized using sol-gel method. Porous scaffolds with varying bioglass composition from 10 to 30 wt% in chitosan, gelatin matrix were fabricated using the method of f...

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 ...

Over the past decades, bioactive glass (BG) has been of a great interest in the bone regeneration field, due to its excellent biocompatibility, bioactivity and osteoconductivity. Herein, fabrication of bioactive glass as one-dimensional fibers by employing an Electrospinning process is reported. The Sol-Gel method was chosen considering the final fibers smoothness and homogeneity. Starting sol ...

objective: one of the major issues in bone tissue engineering is the design and fabrication of bioactive, bioresorbable porous 3d scaffolds capable of maintaining their structure and integrity over a predictable period of time. one such approach is the fabrication of composite scaffolds. methods: in this study we present fabrication and characterization of novel silk/bioglass-composite scaffold...
