title: Correction of a dental arch-width asymmetric discrepancy with a slow maxillary contraction appliance.
abstract: A boy, aged 12 years 3 months, sought treatment for a complete unilateral Brodie bite. His maxillary dental arch was asymmetric, and his dentition was 10 mm wider than normal values for his age. The transverse discrepancy was his chief complaint because it caused a chewing dysfunction. We used a special slow maxillary contraction appliance, which contains a screw, connectors, and retainers, to contract the maxillary transverse asymmetric dental arch. This was followed by preadjusted fixed appliances to level the teeth and adjust the occlusion. A symmetric and functional Class I occlusion was achieved.
