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

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 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.

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.

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.

Glass-ionomers: bioactive implant materials

Biomaterials, 1998
Glass-ionomer cements (GICs) originally designed for use as dental materials have a number of advantages over acrylic bone cements. These include lack of exotherm during setting, absence of monomer and improved release of incorporated therapeutic agents; this has resulted in the development of GICs for biomedical applications.

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.
