In this work, the use of foam-like glass-ceramic scaffolds as trabecular coatings on ceramic prosthetic devices to enhance implant osteointegration is proposed. The feasibility of this innovative device was explored in a simplified, flat geometry: glass-ceramic scaffolds, prepared by polymeric sponge replication and mimicking the trabecular architecture of cancellous bone, were joined to alumin...

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...

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...

conclusions increasing the cu nanoparticles in bioactive glass samples leads to the release of cu2+, which has a positive effect on the antibacterial mechanism, as well as decreasing the cultured staphylococcus colonies found on the bioglasses. therefore, it seems that the nanocomposite/bioglass of cuo is a promising option for aerobic bacterial inhibitor systems in common bone implant infectio...

CuO, Fe2O3, MnO2 and ZnO substituted 45S5 bioactive glasses were prepared. Glass derived Bioactive Glass ceramics were obtained through controlled crystallization of bioactive glasses. The formed crystalline phases in bioactive glass ceramics were identified using X ray diffraction (XRD) analysis. Density and ultrasonic wave velocities of bioactive glasses and glass ceramics were measured and u...
