[The application of repelling magnets to distal movement of maxillary molars. Report of three cases].
Report on three cases of maxillary first molar distalization with the aid of intra-arch repelling magnets were presented in this paper. Two cases were Class II malocclusion and one was a Class I discrepancy case whereby all resulted in rapid distalization of the upper first molars into Class I molar relationship in a relatively short time. Despite the unwanted rotation and tipping of the molars and the anteriors occurred slightly, numerous advantages of the repelling magnetic system were noted applicable to early mixed dentition cases to obtain the sufficient space of the molars rapidly. Moreover, since this is a fixed appliance, no patient cooperation was necessary. In conclusion, this magnetic system was found to be an effective device for molar distalization.
