Bioactive Glasses—Structure and Properties

Angewandte Chemie - International Edition, 2015
AbstractBioactive glasses were the first synthetic materials to show bonding to bone, and they are successfully used for bone regeneration. They can degrade in the body at a rate matching that of bone formation, and through a combination of apatite crystallization on their surface and ion release they stimulate bone cell proliferation, which results in

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.

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

2017
Bioactiveglasses were discovered in 1969 and provided for the first time an alternativeto nearly inert implant materials. They formed a rapid, strong, and stable bondwith host tissues. This article examines the frontiers of research crossed toachieve clinical use of bioactive glasses and glass–ceramics.

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.

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.

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.

Bioactive Glass Three Decades On

Journal of Long-Term Effects of Medical Implants, 2005
Bioglasses were first introduced in the early 1970s and since have found wide use in dentistry. The original 45S5 bioglass, as described by Hench, is a silica-based melt-derived glass characterized by a Si02 content of less than 60%, a high Na2O and CaO content, and a high CaO:P2O5 ratio.

Bioactive glass coatings: A review

Surface Engineering, 2011
Bioactive glasses, discovered by Hench and co-workers at the end of the 1960s, are among the most promising biomaterials for bone repair and reconstruction, mainly thanks to their high bioactivity index. Unfortunately, due to their brittleness and relatively poor mechanical properties, their clinical applications are limited to non-load bearing ...
