Binary CaO-SiO(2) gel-glasses for biomedical applications.

Bioactive materials are routinely used in dental and orthopaedic applications. The concept was first introduced in 1971, with the discovery of 45S5 Bioglass, which is known to develop an interfacial bond between the implant and the host tissue. This glass is composed of SiO(2), CaO, P(2)O(5) and Na(2)O.
