In one aspect, the present invention is directed to an orthodontic bracket (12), comprising: a vertical bore (32); a bendable drop-in hook (34) threaded into the vertical bore (32); and an annular magnetic object (30), in which the drop-in hook (34) is threaded into. In another aspect, the present invention is directed to an orthodontic braces arrangement, comprising: at least two distant brackets (12), each installed on a different jaw of a user; and each of the distant brackets (12) having at least one annular magnetic object (30) secured thereto by a bendable drop-in hook; wherein a distance between magnetic objects of one bracket and another bracket is less than 2 mm; thereby providing intermaxillary attraction or propulsion force, depending on a polarity orientation of the magnetic objects. |
