Seven-year-old female with a thumb-sucking habit, skeletal Class II, 8 mm overjet, right posterior crossbite, constricted palate, and severe crowding.

This 7-year-old patient presented with a severe 6 mm anterior open bite, a persistent left thumb-sucking habit, and a narrow, constricted palate. Additional findings included a tongue-thrust swallowing pattern, abnormal anterior tongue posture, and a missing lower incisor. The combination of the thumb-sucking habit, tongue thrust, and transverse maxillary constriction was contributing to the developing open bite and abnormal eruption pattern.

This 6-year-old patient presented with severe crowding in the lower arch and moderate crowding in the upper arch, with insufficient space for the developing permanent teeth and blocked-out upper lateral incisors.
