An orthodontic cantilever arm includes a wire segment with an outer end portion having a generally “C”-shaped configuration. One leg of the outer end portion is received in a passageway of an orthodontic anchorage device such as a temporary implant and the other leg bears against an outer surface of the anchorage device. The cantilever arm also includes an elongated arm portion, and the two legs of the outer end portion cooperate with each other to restrict certain types of movements of the arm portion.
