This tutorial gives the essential information needed for good overbite control. It should be possible in every case if a systemized approach is used and five key principles are followed.

Understanding overbite

– the vertical and horizontal components
– overbite in Class II/1, Class II/2, and reduced overbite cases

Using the .0227 slot

– less arch wire deflection in the larger slot
– why reverse curves are seldom needed

Avoiding extractions in low angle cases

– the mechanics for overbite control will be easier

Including the lower second molars

– how inter-maxillary elastics can help overbite control in deep bite cases…
– but are best avoided in cases with  reduced overbite

Allowing time for the mechanics to work

– distal movement of the lower canine roots is needed
