Kovacs, US patent 5573401, (1996)]. Each of the above-mentioned correction lines is a metal having a dazzling silvery white color. For aesthetics, there are also transparent orthodontic wires, even transparently oriented wires of nanostructures. For example, Lemchen recently proposed a very different mesoporous (meS0p0r0US) alloy correction line [M s Lemchen, training __ 6056545, (2000)]. The polymoploy alloy correction line invented by Lemchen has a transparent nature of 1281389, which is not as restrictive as the original dense wire. It is expected that its mechanical properties are strong. This use of orthodontic lines is very current in the prior art. There is no anodized treatment of the anode. Yuan Wang does not have different color of orthodontic orthodontic lines, and there is no orthodontic line. SUMMARY OF THE INVENTION The present invention uses an anodized method to treat a tooth (four) positive line, except ? : In addition to the nature of its compilation, it can produce a variety of single appearances, = (four) t teeth (four) positive lines. The choice of materials used in the method of the present invention is based on the fact that the second best-acting stainless steel wire and form can be used. Compared with the existing correction wire, the product will not have any significant difference in the mechanical S' and the appearance of various single-color or colorful face can meet the needs of modern people who like to show their personality. Embodiment Original silver white light The present invention discloses a metal orthodontic line having a color other than its metal in appearance. Preferably, the color is formed by anodizing. Preferably, the metal orthodontic line has a single color. Preferably, the metal orthodontic line has a plurality of colors. Preferably, the orthodontic line of the present invention is preferably made of titanium and bismuth 1281389. The orthodontic line of the present invention is made of a preferred alloy of titanium-nickel based alloy. The orthodontic line of the present invention is preferably made of stainless steel, and the orthodontic line of the present invention has a color selected from the group consisting of blue, yellow, purple, green, golden or brown. The present invention also discloses a method of preparing a dental bridge positive line of the present invention comprising the steps of: a) cleaning a metal orthodontic line; and b) anodizing the cleaned metal tooth green line obtained from step a) 'On the surface of the metal orthodontic line, a color other than the original silver white gloss of the metal is obtained, wherein the anodized electrolyte is an acidic aqueous solution. Preferably, an operating voltage of the anode treatment is ι〇ν~6〇ν. Preferably, the cleaning comprises immersing the metal orthodontic wire in an acidic aqueous solution, more preferably in an aqueous solution of hydrochloric acid. Since the orthodontic line is placed in the oral cavity of the human body, the compatibility of the organism is very important, so the general coloring or pigment coating technique cannot be applied to the coloring of the orthodontic line. The coloring method of the anodizing treatment utilizes the optical interference effect of the oxide film on the surface of the material, and is not an additional pigment. The product after the anthracene treatment is an oxide of the orthodontic line, so the anodized product does not introduce additional biocompatibility issues. The anodic treatment is to thicken the oxide on the metal surface. According to the general metal material, the oxide is usually more stable than the metal, that is, the biocompatibility may be better than 1281389. As a result, the anode treatment of the present invention does not significantly affect the mechanical strength of the wire because it is only vaporized on the surface. That is to say, the technology of the anode treatment can change the color of the appearance, and the biological phase grain and mechanical strength will not be greatly changed (the former may be slightly improved, the latter may slightly decrease or slightly improve the previous treatment of titanium anode treatment) Quite (G·G·· Turner, GB1100913, 1968; Shreir, GB962904, 1964; Kendull, US3663379, 1972; Kaminski, US60293 90, 2000), but mainly on the structure of Ti. In the known art There is no anodic treatment technique for the orthodontic line, and there is no known method for the anodic treatment of the TiNi phase.

The device is the LPS 305 of MOTECH. The NiTi alloy orthodontic wire is immersed in 〇·5Μ Na0H and ultrasonically oscillated for 5 minutes. This washing step can remove the surface ester. And the surface of the activated metal is made to have the same surface properties. After that, it is shocked with hydrochloric acid (3〇g HCl/100ml^O) for 10 minutes. The purpose of pickling can remove the oxide on the metal surface. Finally, it is washed with a large amount of distilled water. Blow dry. Anode treatment was carried out at room temperature with a constant voltage, the operating voltage was 10 V, and the anode treatment time was 120 minutes. Then the NiTi Ϊ281389 was removed: the orthodontic line was washed with distilled water and then blown dry. The tooth line of the blue appearance is obtained.
