Treatment of a high angle class II malocclusion with severe crowding and enlarged adenoids: a case report.

AIM: The aim is to present the treatment of an 11-year-old, hyperdivergent, Class II division I, female patient with a history of enlarged adenoids and severe arch length discrepancies.

METHODS

The malocclusion was treated by upper right molar distalisation and first premolar extractions. Accurate diagnosis, meticulous treatment planning and an unexpectedly favourable growth pattern lead to a highly satisfactory outcome.

RESULTS

There was a significant improvement in facial profile, overjet and occlusion. A significant decrease in the mandibular plane angle was recorded, without the use of any extra-oral appliance.

CONCLUSION

The treatment results remained stable after six years of retention following maintenance of the favourable growth pattern.
