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.

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.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
