According to a first aspect, the present invention relates to a method of surface treating metal elements (2) intended for odontological use, such as brackets, molar tubes and dental arches. The metal elements are coated with a surface layer (23) for imparting a tooth-like colour to the elements and also to prevent the leakage of nickel. According to the inventive method, the surface layer (23) is applied by electrocoating. The invention also relates to such elements produced in accordance with the method.
