A Case Report of Angle Class II Malocclusion with Thumb-sucking

A case was presented of Angle Class II malocclusion with maxillary protrusion associated with thumb-sucking over an extended period, from infancy to age 10. As the first objective of treatment was the elimination of thumb-sucking, we instructed the patient in myofunctional therapy. As this was unsuccessful after a year, we installed a palatal crib, which successsfully eliminated the pernicious habit. The maxillary first premolars were subsequently extracted, and the 2nd phase of treatment was begun with edgewise appliance to correct the occlusion. The result showed class I molar relation and good occlusion, and the soft-tissue profile was remarkably improved
