Metal-vitreous Biocide Coating

Abstract

Develop materials capable of to improve the osseointegration mechanisms is an important contribution in health care, especially in orthopedics and dentistry. Even when the materials provide good osseointegration characteristics (biocompatible) many implants may suffer infections in surgery. This project proposes to develop a vitreous material covering metallic surface of a biomaterial (titanium alloys and stainless steel) with biocide characteristic. This work provides preliminary results from these vitreous material based on glass system SiO2CaONa2OMe. This study realized the replace of the boron by niobium (Me=Nb), intending obtain good behavior in osseointegration (to comparative basis: composition with a considerable amount of boron had very good response as a biocide agent). Nb seems to be very useful on vitreous lattice. The materials were characterized by Xray diffraction (XRD), scanning electron microscopy (SEM) and biocide activity.
