Comprehensive treatment commenced in the mixed dentition and completed in the permanent dentition: an “early treatment” malocclusion

The management of a ten-year-old female with an Angle Class II division I malocclusion is followed for nearly ten years, through active treatment, until follow-up same years later. Note is made of: the duration of the overall active treatment period; the need for considerable patient cooperation; the fact that the lower incisors did not move forward on their underlying bone while stili moving forward in relation to the APo line; and the fact that, in this instance, the third molars were chosen as appropriate teeth for extraction.
