Figure 2

The effect of rapid palatal expansion upon our patient’s upper airway. This figure illustrates the effect of rapid palatal expansion on our patient’s bite. The upper panel demonstrates the opening of his bite (arrow) as the mandibular teeth tilt outwards to meet their counterparts in the expanded maxillary arch. The middle panel demonstrates the widening of the maxillary arch by 0.5cm at the level of the bicuspids after rapid palatal expansion. Notice the narrow, high palatal arch before rapid palatal expansion. The lower panel illustrates the outward tilting of the mandibular teeth following rapid palatal expansion (inward arrow before and outward arrow after rapid palatal expansion).
