Optimal Projection and Characterization of
a Bioactive Vitroceramics Used in Reparatory Modern Medicine

Abstract:

Biocompatible and bioactive vitroceramic materials have low mechanical properties, thus they can only be used for manufacturing implants that can support low stress forces. The best way for an implant to meet all requirements (biocompatibility, bioactivity and high mechanical properties) is the covering of a biocompatible and bioinert metallic material (titan or special steels) with a biocompatible and bioactive vitroceramic material. The greatest problem that appears when obtaining such a metal-covering couple is achieving an adherence that is as good as possible, thing that presents great difficulty in the case of a metal-vitroceramic system because of the great difference between the properties of the two materials.That is why an optimal projecting of the vitroceramic material is imposed, so that the final composition insures the best values from the point of view of adherence and bioproperties. The work present hereby proposes the optimal projecting, obtaining and characterisation of such a vitroceramic within the SiO2-B2O3-P2O5-CaO-MgO-Li2O-Na2O-K2O-TiO2 oxidic system. In a primary stage, a mathematical model of calculating the oxidic composition of the vitroceramic was elaborated. This minds a series of thechnological conditionings which are specific to bioactive materials. On the basis of the results obtained after the resolving of this mathematical model, the vitroceramic was processed. The obtained vitroceramic material was tested from the point of view of the physico-chemical properties and for the bioteste that present interest. Non-citotoxicity and pH dynamics tests have also been effectuated using a solution that imitates the human blood plasma (SBF) and also biotests of cellular proliferation using osteoblaste cells cultures. Keywords: biovitroceramic, optimal projecting, obtaining and characterization
