Patient Chief Concern
Posterior crossbite

What learning would you share with other Invisalign providers?
Using TADs to resolve a posterior crossbite early on helps simplify the overall treatment process.

What contributed most to this treatment being successful?
By intruding the maxillary molars with TADs, the posterior crossbite was corrected first. This eliminated occlusal interferences, which facilitated the subsequent tooth movements.
