Commentaires

  • 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
  • while maintaining a Class 1 bite relationship.
