Invisalign Comprehensive

Patient Chief Concern
Protrusion, anterior open bite, and retruded chin

What learning would you share with other Invisalign providers?
Premolar extraction treatment to resolve severe crowding and high canines is common. I would like to emphasize that, with the strategic use of intermaxillary elastics, treatment with Invisalign aligners is not inferior to conventional fixed appliance therapy in terms of treatment outcomes or duration.

What contributed most to this treatment being successful?
During space closure, appropriate use of elastics and power chains to modulate anchorage value and achieve a Class I molar relationship.
