Abstract
Implantation materials for the living body comprising: 10 to 4000 ppm of gaseous ingredients combined, mainly composed of oxygen; up to 100 ppm of ingredients other than the gaseous ingredients such as iron; and the balance titanium. An oxide film is formed on the surface, where necessary, by anodizing or the like. Titanium fixation wires for implanting in the living body composing: up to 300 ppm oxygen, up to 50 ppm hydrogen, up to 200 ppm nitrogen, and up to 400 ppm carbon, all as gaseous ingredients; up to 100 ppm of ingredients other than the gaseous ingredients such as iron; and the balance titanium. For applications where strength is the primary consideration, the wires comprise: from more than 100 to 1000 ppm of iron; up to 250 ppm oxygen, up to 50 ppm hydrogen, up to 170 ppm nitrogen, and up to 400 ppm carbon, all as gaseous ingredients; up to 100 ppm of iron and ingredients other than the gaseous ingredients; and the balance titanium.
