In vitro evaluation of CaO-P2O5-SiO2-Na2O-TiO2 basedCeramic System.

      Аннотация: Bioceramics are frequently used in medical industry to replace the faulty organs and diseased tissues in living organisms. This field has benefited a large number of people. The history of implantation is not new but with the development of new technologies, the use of bioceramics inside human bodies has now become widespread.Bioactive materials are of special interest for their wide range of properties including their fast reaction rates responsible for their attachment to bone, their non-toxic nature and ease to control their reaction rates by modifying their composition according to particular function.Bioactive materials utilizes the fact that apatite is an important mineral phase of bone and these materials also form tight bonding to bone via formation of apatite layer on their surface.Bioactive materials are the most effective materials to be used as bone grafts to fill the gaps between the neighboring bones. On implantation inside the body these materials develop a biologically active surface layer of apatite which bonds tightly to bony apatite and in this way the gap is filled by newly formed tissues. It means that the formation of apatite is the most important requirement.
