Abstract:
Two types of surface treatments (Low pressure metal organic chemical vapor
deposition (Ti-MOCVD) and anodized Ti) have been conducted on Ti to
improve their osteointegration properties in view of dental implant
application. The two typologies of surfaces have been characterized in
vitro both regarding the corrosion and the in biological behaviour in
comparison with the Ti machined surface. The corrosion tests showed that
both the surface treatments reduced markedly the corrosion rate compared
to Ti machined. The biological tests showed that all specimens are
cytocompatible and significant differences among them were detected. In
particular WST1 tests showed more viable osteoblasts adhering to MOCVD
specimens in comparison with the other surfaces.
