[Asymmetrical distalization of upper molars with magnets. A clinical case].

The treatment of a patient with an asymmetric malocclusion (class II, division I--subdivision) was presented. The treatment involved the use of repelling magnets for the distalization of the upper right molar which was in a class II relationship. A fixed "Nance" appliance attached to the second premolars was used for anchorage. Magnets are relatively easy to insert, are well tolerated, and they can distalize molars rapidly without significant loss of anchorage. No cooperation was required during the distalization phase of treatment and the second premolar distalized spontaneously once the "Nance" appliance was removed.
