ABSTRACT:
An orthodontic appliance in which friction is reduced between an archwire and its archwire holding element by means of repulsive forces. The repulsive forces are due to magnetic or electrical fields. The archwire holding element may be a tube, or a pair of tie wings and a slot. The archwire holding element generates a field having a sign. The archwire generates a field proximate to the archwire holding element having an identical sign. A repulsive force is therefore produced. The repulsive force minimizes contact between the archwire holding element and the archwire. This reduces frictional binding, which reduces the treatment time and/or the force necessary for successful orthodontic treatment.
