- The desired results were obtained by expansion of arches with MARPE pre-ortho treatment.
- Coordination of both upper and lower dental arch shape by expansion on the upper arch.
- Distalisation of lower posterior teeth to achieve class I molar relationship.
- Correction of lower midline deviation
- Power ridges on lower incisors to prevent periodontal complications such as gingival recession or alveolar bone dehiscence.
