Aim: This case demonstrates an unusual orthodontic and surgical approach to the treatment of an asymmetrical Class III malocclusion. Methods: The use of bilateral bite blocks with repelling magnets
and extrusive elastics resulted in leveling of the maxillary occlusal plane, and thus obviated the need for maxillary surgery. The unilateral bite plates had an intrusive effect on the mandibular dentition and, in conjunction with the extrusion of the maxillary teeth on the left, provided the presurgical dental movements that allowed a successful mandibular rotation and setback. Conclusion: The combined orthodontic/orthognathic surgery treatment resulted in a significant correction of the facial asymmetry and dental and functional improvement. World J Orthod 2001;2:33–44.
