Patient Chief Concern
The patient's chief complaint was an unesthetic smile due to anterior tooth protrusion.

What learning would you share with other Invisalign providers?
Staging is critical in an extraction case requiring maximum anchorage. Distalizing the canines first, followed by the incisors, reduces the risk of anchorage loss; however, attention must be paid to maintaining arch width and placing attachments on the incisors to prevent off-tracking.

Clinical Indications

Class II div 1
Deep bite
Increased overjet
Narrow arches
Spacing

The patient exhibits flared teeth, anterior crowding-free spaces, and a bilateral Class II canine relationship, with spaces between the upper incisors. The treatment plan indicates the extraction of all four first premolars to reduce anterior protrusion.

Modalities

First Premolar extraction
Intrusion
Leveling Curve of Spee
Overtreatment
