Full description

What is the effect of the different treatment modalities (distalization versus upper premolar extraction) of class II malocclusion on the position, inclination and incidence of impaction of the upper third molars? Pico P: Adolescent patients with class II malocclusion having bilateral developing upper third molars.

I: bilateral upper first premolar extraction orthodontic treatment with moderate anchorage.

C: distalization orthodontic treatment. O: Primary: angulation of the maxillary third molars.
