1. Biogenic synthesis of silver nanoparticles from thyme extract for functionalization of a bioactive glass produced from rice husk ash
Abstract The rice husk, agro-industrial residue, stands out for having silica, the main oxide former of the bioactive glass. To avoid contamination in this biomaterial, substances with bactericidal properties, like silver can be incorporated. Thus, the objective of this work is the synthesis of silver nanoparticles to functionalize a bioactive glass synthesi

4. A RETROSPECTIVE CASE-SERIES ON THE USE OF S53P4 BIOACTIVE GLASS FOR THE ADJUNCTIVE TREATMENT OF SEPTIC DIAPHYSEAL NON-UNION
RESUMO Objetivo: A não união e a persistência de infecção no local de uma fratura por períodos prolongados são sempre descritas como desafios para os ortopedistas, especialmente em casos de fraturas expostas graves, com cominuição e perdas de segmentos ósseos. Esta é uma série de casos de não consolidações infectadas, utilizando o vidro bioat

5. Evaluation of an antibacterial orthodontic adhesive incorporated with niobium-based bioglass: an in situ study
Abstract This in situ study aimed to evaluate the antibacterial and anti-demineralization effects of an experimental orthodontic adhesive containing triazine and niobium phosphate bioglass (TAT) around brackets bonded to enamel surfaces. Sixteen volunteers were selected to use intra-oral devices with six metallic brackets bonded to enamel blocks. The experim

6. Fabricación de recubrimientos compuestos de Bioglass®/poli(ɛ-capro-lactona) obtenidos por co-deposición electroforética sobre acero inoxidable
ABSTRACT In this work two kinds of "soft coatings" were obtained by co-electrophoretic deposition technique (co-EPD). In all cases a bioglass was used as inorganic phase, and a commercial poly(ɛ-caprolactone), (PCLC), and an anionic synthesized PCL modified with maleic anhydride (PCLS) were used as organic phase. To ensure an adequate coating over the metal

7. Obtención y caracterización de recubrimientos de biovidrio sobre la aleación de Mg AZ31
ABSTRACT The ideal material for a metal bone prosthesis must undergo a gradual corrosion in vivo, without releasing toxic components, while acting as a support and facilitating the growth of bone tissue, until a replacement is completed by the regenerated bone. . Biodegradable magnesium alloys have been studied because of their excellent mechanical propertie

8. Fabrication of Multiple Layered Scaffolds with Controlled Porous Micro-Architecture
A multi-layer scaffold that incorporates bioglass, phosphatidylserine and steroidal saponins loaded collagen microparticles was prepared in this study. Combinatorial processing techniques involving porogen leaching protocol and freeze-drying were used. Drug distribution and microstructure could be controlled mainly by the concentrations of drug-loaded collag

9. Copaiba oil effect on experimental jaw defect in Wistar rats
PURPOSE: To evaluate the effects of copaiba oil on jaw defects repair in Wistar rats treated with bioglass or adipose tissue. METHODS: A jaw defect was randomly created in forty-two rats and filled with bioglass or adipose tissue. The two groups (Gbio and Gcell) were subdivided in three subgroups with seven animals each according to gavage administration: c

10. Bioactivity of leucite containing glass - ceramics using natural raw materials
Glass compositions were carefully prepared, using natural quartz and potassium feldspar as a part of the starting raw materials. The solids were prepared so as to have theoretical stoichiometric leucite and 45S5 Bioglass in different L/Bg weight ratios between 0.43 - 1.00. Novel bioactive glass - ceramics, containing leucite, sodium calcium silicate and sili

11. Scaffolds of PDLLA/bioglass 58S produced via selective laser sintering
Scaffolds of PDLLA were produced to be implemented in maxilofacial surgeries inducing bone repair and regeneration. To prepare these scaffolds, bioglass (BG58S) was synthesized by sol-gel method, in order to be applied as osteoconductive dispersed particles in PDLLA matrix. Once presenting greater facility on parts fabrication, this polymeric matrix enables
