Patient Chief Concern
Crowding and protrusion

What learning would you share with other Invisalign providers?
In premolar extraction cases for treating severe crowding, Invisalign aligners have significant advantages over bracket orthodontics, as it can avoid round tripping during the leveling and alignment phase and allows extraction space closure to begin from the early stages of treatment.

What contributed most to this treatment being successful?
Use of unilateral Class II elastics during Additional Aligners to achieve a Class I occlusal relationship through midline correction and anchorage control.
