  • Metal substrate modified with silicon based biomimetic treatment having antibacterial property for the osteointegration thereof
    Patent number: 9353453
    Abstract: A substrate of a metal selected from the group consisting of titanium, tantalum, titanium alloys and tantalum alloys, modified by anodic spark deposition (ASD) on the surface thereof of a microporous and nanoroughened layer of the oxide of the same metal, said layer being enriched with Ca, P, Si, Na, and at least one metal selected from Ag and Ga. This surface modified metal substrate show excellent osteointegrating properties associated with antibacterial activity. A further advantage resides in that its preparation process does no longer require alkaline etching to promote cellular adhesion.
    Type: Grant
