Early Class II treatment.

The treatment of children presenting with a Class II division I malocclusion involves one of two approaches. The first provides treatment in two phases; one of intervention during the mixed dentition (phase I) followed by a second definitive course of appliance treatment in early adolescence (phase II). The second approach involves providing a single course of comprehensive therapy during adolescence. The debate for and against early treatment is discussed alongside key, clinically relevant evidence related to Class II division I malocclusions.
