Osteoconductive/osteoinductive titanium/titanium alloy implant, comprises additional element in titanium oxide obtained by anodic oxidation

摘要

Osteoconductive/osteoinductive titanium/titanium alloy implant comprises an additional element in the titanium oxide obtained by anodic oxidation. The additional element is calcium, phosphor, or sulfur. Osteoconductive/osteoinductive titanium/titanium alloy implant comprises an additional element in the titanium oxide obtained by anodic oxidation. The additional element is calcium, phosphor, or sulfur. The implant exhibits a cross-section of the osteoconductive/osteoinductive oxide layer, which consists of a double layer structure of an upper porous layer and a lower compact barrier layer. An Independent claim is also included for a method of producing an osteoconductive/osteoinductive titanium/titanium alloy implant, which comprises: (1) providing anodic electrochemical oxidation of the titanium/titanium alloy implant in an electrolyte (3) containing additional component(s); and (2) controlling the anodic forming voltage transient with slope (dV/dt), to produce an oxide layer on the titanium/titanium alloy implant exhibiting a double layer structure of an upper porous layer and a lower compact barrier layer.
