[Treatment of cross-bite of anterior teeth with rare earth magnetic appliance with double rails].
In this paper, the rare earth magnets (Nd-Fe-B) were used for treatment of cross-bite of anterior teeth. Eight patients were selected. In an attempt to achieve the labial movement of upper anterior teeth, removable appliance with repelling magnetic force were used. The treatment results are satisfactory. The following facts were discussed: (1) the direction of the repelling magnetic force can be controlled well with the double rails; (2) the time for treatment was short and there was no manifestation of unfavorable reaction and (3) no adverse bioeffects have been reported in regard to the use of this kind of device.
