The treatment of a skeletal Class II, Division 1 malocclusion in the early permanent dentition is described. The patient had a vertical facial pattern and lower arch crowding; four premolars were extracted. Although some anchorage was lost in the maxillary arch and the face developed in a predominantly vertical direction, the final result demonstrated a well-balanced and pleasing profile.
