- Correction of the malocclusion was achieved mainly through expansion of the maxillary and mandibular buccal segments.
- The first permanent molars were rotated mesial outward, while the deciduous molars were expanded bodily.
- The expansion was performed sequentially starting with rotation first permanent molars and followed by bodily expansion. This protocol is to ensure good anchorage control.
- The crossbite was corrected by proclining the upper incisors.
- Spaces, equal to the size of the deciduous canines, were maintained.
