Invisalign First

Patient Chief Concern
Ectopic canine

What learning would you share with other Invisalign providers?
It's important to do the space management in the mixed dentition period. Especially when the canine erupted buccally, the arch length would be decreased, which would result in the later crowding of the buccal segment permanent teeth.

Clinical Indications

Class II div 1
Crowding
Ectopic
Edge to edge bite
Mandibular midline deviation
Midline shift

Canine ectopic resulted in the molar moved mesially and the arch length decreased. And this would lead to the crowding of buccal segement.

Modalities

Palatal Expansion
Space Closure

We expanded the upper arch and left space for the canines and stopped the molars from mesial movement.
