ABSTRACT:
An orthodontic buccal tube device adapted to cooperate with an arch wire and comprising a base member for attachment to a tooth, and a body member which is fixed to the base member and which comprises a bore adapted to accommodate an end portion of the arch wire. The device comprises an auxiliary member fixed to or integral with either the base member or the body member and is adapted for cooperation with an end of the wire protruding from the bore to either limit the rearward movement of the wire, or exert a force bringing to the development of a moment in the wire, or both. The auxiliary member is also useful in forming an abutment in the direction of the buccal-mucosa, for ensuring appropriate distance between the buccal-mucosa and the end of the wire so as to avoid injuries to said mucosa.
