Comments

  • A previous expansion of the maxilla was done.
  • After the expansion this case was prepared for orthognatic surgery.
  • Only Invisalign without any other appliance or need for elastics was used for the preparation.
  • Over correction of the posterior crossbite was planned to ensure that we would not have premature contacts in the immediate postoperative period.
  • Between 3.4 and 3.5 we did only 0.3mm IPR to strengthen the closure of spaces.
  • ¬†Small midline deviation was corrected with additional aligners.
  • Tooth 1.7 was extracted because it had no antagonist and the patient did not wish to place an implant in the region of 4.7

Retention

  • Maxillary:
  • Mandibular:
