Abstract
A method and apparatus are provided for marking orthodontic products. The method includes the steps of coupling the orthodontic product with the anode of a power source, placing an electrolyte in electrical contact with the cathode of the power source, and selectively exposing portions of the orthodontic product to be marked to the electrolyte. The apparatus includes a hand marker connected to the cathode of a power source. A sponge pad soaked with an electrolyte is attached to the hand marker. A workplate provided for holding the orthodontic product is coupled to the anode of the power source. A stencil is also provided to enable selective portions of the orthodontic product to be exposed to the electrolyte and thereby be marked.
