A 12-year-old female in the late mixed dentition with a class II division 1 incisor relationship on a moderate skeletal class II pattern with reduced MMPA. The malocclusion is complicated by:
• Increased overjet (12mm)
• Increased and complete overbite
• Crowding of both arches
• Mild molar–incisor hypomineralization.

Is removal of the URE, ULE and LRE indicated at this point? How would you treat this malocclusion? What are the potential orthodontic problems associated with removal of the first permanent molars? What prescription should be used during the fixed appliance phase?

I have tried my best to explain the case in the following images! Happy reading
