Bioactive glass calcium phosphate ceramics

Development of nano-structured alumina and zirconia ceramics and composites as well as nano-structured calcium phosphate ceramics and porous bioactive glasses, possibly as composites with organic constituents, will provide desired properties for bone substitution and tissue engineering for the next 20 years (Chevalier and Gremillard, 2009). [Pg.450]

Ceramics used in fabricating implants can be classified as nonabsorbable (relatively inert), bioactive or surface reactive (semi-inert) [Hench, 1991,1993] and biodegradable or resorbable (non-inert) [Hentrich et al., 1971 Graves et al., 1972]. Alumina, zirconia, silicone nitrides, and carbons are inert bioceramics. Certain glass ceramics and dense hydroxyapatites are semi-inert (bioreactive) and calcium phosphates and calcium aluminates are resorbable ceramics [Park and Lakes, 1992]. [Pg.599]

In their 2006 review, Boccaccini et al. [78] elaborated on the study of combinations of many biodegradable polymer matrices reinforced with inorganic ceramics, bioactive glasses and glass-ceramics, and calcium phosphates as scaffolds for bone tissue engineering applications. [Pg.498]

Phospha.tes. Many phosphates cl aim unique material advantages over siUcates that make them worth the higher material costs for certain apphcations. Glass-ceramics containing the calcium orthophosphate apatite, for example, have demonstrated good biocompatibiUty and, in some cases even bioactivity (the abiUty to bond with bone) (25). Recent combinations of fluorapatite with phlogopite mica provide bioactivity as well as machinability and show promise as surgical implants (26). [Pg.325]
