In the past decade, tissue engineering-based bone grafting has emerged as a viable alternative to biological and synthetic grafts. The biomaterial component is a critical determinant of the ultimate success of the tissue-engineered graft. Because no single existing material possesses all the necessary properties required in an ideal bone graft, our approach has been to develop a three dimension...

Plasma sprayed bioactive glass coatings were studied using crushed 45S5 powder. It is widely accepted that plasma coating microstructure highly affected by the characteristics of powder and parameters set on spraying process. Once deposition was optimized, two strategies carried out to analyse their effect adhesion: cooling with carbon dioxide while a post heat treatment as-sprayed coatings. Sc...

3D printing for tissue engineering requires biomaterials with mechanical and biological properties suitable both regeneration the process. A filament made of poly(hydroxybutyrate-co-hydroxyvalerate) (PHBV) combined 45S5 Bioglass (BG) was used to print scaffolds by fused deposition modeling (FDM). Chemical treatment BG particles chlorotrimethylsilane (CTMS) improved ductility extruded filaments ...

background: the greater surface of bioactive glass nanoparticles presents an incomparable and promising feature similar to the biological apatite. nanoparticles improve cellular adhesion, enhance osteoblast proliferation and differentiation, and increase biomineralization for periodontal regeneration and dental implants. considering the fact that interaction between periodontal cells and bone g...

bioactive materials including glass and glass-ceramics are nowadays used as medical implants for orthopedic applications. in this study several samples of glass-ceramics have been prepared using both heat treatment and sol-gel processes. the structure and bioactivity of these samples based on their interaction with simulated body fluid (sbf) have been determined. in-vitor, using the raman spect...

The present work investigates, in situ, the in vitro bioactivity of partially crystallized 45S5 Bioglass (BG) as a function of immersion time in a simulated body fluid (SBF) using atomic force microscopy (AFM). The results obtained for the crystallized BG were compared to those of hydroxyapatite c- and a-faces. The calcium phosphate layer grows on the crystallized 45S5 B by multiple two-dimensi...

objective: bioactive glass is often used as a filler material for repair of dental bone defects. in different studies osteogenic potential of this material was proved, but its dentinogenesis property is in doubt. the purpose of this study was to evaluate the histological pulp responses of calcium hydroxide and bioactive glass placed directly on exposed pulp tissues. materials and methods: twent...
