After U:32+28 and L:24+28 Invisalign First aligners, the anterior crossbite, posterior crossbite, narrow upper arch, and crowding were all corrected
Adequate space prepared for the permanent upper canines and the gingival health around the lower left central incisor was stabilized
Good aligner wear compliance and oral hygiene were maintained throughout Phase 1 treatment
The Phase 1 treatment time was 13 months, not including the pre-treatment eruption monitoring and passive vacuformed appliance phase. Note: This extra step is not needed in patients who do not require an acclimation phase due to the medical condition.
The final photos show the dentition 12-months post Phase I treatment
The goals for Phase 2 are to close the remaining lower spaces, extrude the upper left canine, and de-rotate the premolars
