Bioactive glasses as accelerators of apatite bioactivity

Journal of Biomedical Materials Research Part A, 2003
AbstractSynthetic carbonatehydroxyapatite is the ceramic closest to the mineral component of human bone and seems, therefore, the optimum material to use in osseous implants. However,in vitroassays performed to determine its bioactivity have shown no positive results after 2 months of assay.

The in-vitro bioactivity of mesoporous bioactive glasses

Biomaterials, 2006
Ordered mesoporous bioactive glasses (MBGs) with different compositions were prepared by using nonionic block copolymer surfactants as structure-directing agents through an evaporation-induced self-assembly process. Their in-vitro bioactivities were studied in detail by electron microscopy, Fourier-transform infrared spectroscopy, and inductively ...

Bioactive Glasses and Glass-Ceramics

2021
The application of some special glass compositions to make implantable biomaterials has revolutionized the medical field and introduced the concept of “surface-active” or “bioactive” materials, which have the ability to elicit a specific biological response at the interface with the surrounding tissue.

Characterization and in vitro Bioactivity of Zinc-containing Bioactive Glass and Glass-ceramics

Journal of Biomaterials Applications, 2006
Zinc-containing glass is prepared by the substitution of CaO in 58S bioactive glass with 0.5 and 4 wt% ZnO, and glass-ceramics are obtained by heat-treating the glass at 1200 C. The bending strength and in vitro bioactivity of the glass and glass-ceramics are evaluated. The results indicate that Zn promotes the crystallization of SiO2 and wollastonite

Bioactive glasses and glass-ceramics

Clinical Materials, 1993
Bioactive materials are designed to induce a specific biological activity; in most cases the desired biological activity is one that will give strong bonding to bone. A range of materials has been assessed as being capable of bonding to bone, but this paper is solely concerned with bioactive glasses and glass-ceramics.

Carbonate Formation on Bioactive Glasses

Langmuir, 2004
The system termed 58S is a sol-gel-synthesized bioactive glass composed of SiO2, CaO, and P2O5, used in medicine as bone prosthetic because, when immersed in a physiological fluid, a layer of hydroxycarbonate apatite is formed on its surface.

Bioactivity evolution of the surface functionalized bioactive glasses

Journal of Biomedical Materials Research Part B: Applied Biomaterials, 2014
AbstractThe formation of a calcium phosphate layer on the surface of the SiO2–CaO–P2O5 glasses after immersion in simulated body fluid (SBF) generally demonstrates the bioactivity of these materials. Grafting of the surface by chemical bonding can minimize the structural changes in protein adsorbed on the surface.
