Title:
BIOLOGICAL IMPLANT AND METHOD FOR PRODUCING SAME
Document Type and Number:
WIPO Patent Application WO/2014/136567
Kind Code:
A1
Abstract:
A base of this biological implant, said base being formed of titanium metal or a titanium alloy, is subjected to an alkali treatment and an ammonia treatment, so that the surface of the base is provided with a modified layer that has a network structure. The modified layer is characterized in that at least the surface thereof contains an anatase titanium oxide phase but does not substantially contain an amorphous phase of an alkali titanate.
