Abstract

The desire of reestablishing the human organism’s normal functions imposes the utilization, in modern reparatory medicine, of bioactive materials such as tricalcic phosphate, hydroxyapatite, bioglasses and biovitroceramics. These kinds of materials are well accepted by the living organism (biocompatible), they can connect to the living tissue (bioactive) but they do not posses the adequate mechanical properties. If such materials are intended to be used for making large implants that have to support high pressure, like the hip prothesis, the solution is to cover biocompatible metallic materials (titan, special steel) with biocompatible and bioactive vitroceramic coatings, the metalic structure providing the needed high mechanical properties. This work proposes to obtain such a new biovitroceramic material, within the SiO2-CaO-MgO-Li2O-K2O-Na2O P2O5-TiO2-B2O3 oxide system, and to test it for its physico-chemical properties that present interest (dilatation coefficient, chemical analyze, X-ray diffraction, etc). Have also been effectuated non-citotoxicity and pH dynamics tests utilized a solution that imitates the human blood plasma (SBF) and biotests of cellular proliferation using osteoblaste cells cultures..
