The present invention relates to a method for manufacturing a coated orthodontic wire, in which the surface of a coated orthodontic wire, that is installed to connect teeth to each other to correct the alignment of the teeth, is etched, then plated with silver, and then coated with a polymer compound, so as to remarkably increase manufacturing speed and also allow the coating to be maintained for a long time due to the superior durability thereof. It may be expected from the above-mentioned configuration of the present invention and from the clinical results that there may be effects according to a method for manufacturing a coated orthodontic wire in that: a plurality of metal wires are fixed by using a jig, the metal wires are etched and plated in a state of being spaced apart from each other while only a required portion thereof is dipped into a container.
