<p>PROBLEM TO BE SOLVED: To easily perform orthodontic work by forming deviation of a phase in the left and right direction to a pair of wings formed in the up and down direction on the face of the opposite side to a tooth fixing face of a bracket main body fixed on the tooth by placing intermediately a slot for hooking an arch wire. SOLUTION: One face of a bracket main body A for orthodontics is made a flat fitting face fixed by a fixing means such as an adhesive on a tooth surface and a slot 1 for inserting horizontally an arch wire is formed in the neighborhood of the upper and lower center of the opposite side face to this and the upper and the lower parts of the slot 1 as a pair are made to be an upper wing 3 and a lower wing 4 wherein a binding wire inserting channel 2 being continued in the horizontal direction on the fitting face side is provided. In addition, to an overlapping c1 of the upper wing 3 and the lower wing 4 when the phase is deviated in the horizontal direction, the deviation of the phase to be necessary for orthodontics such as less overlapping than this is appropriately formed. In addition, cuttings 5 are formed on the upper wing 3 and the lower wing 4 and a hook part 6 for binding the binding wire is formed.</p> |
