评论

  • The initial set of aligners was made of 38 steps.
  • For the correction of the crowding and anterior crossbite, the upper arch was expanded.
  • Lingually positioned tooth #1.2 was moved labially and proclinated.
  • For the correction of crossbite and bite jumping of tooth #1.2, occlusal attachments on the lower second molar (#3.7 and 4.7) were made during the aligner 1 - 30.
  • IPR was conducted on the upper and lower anterior teeth.
  • Patient showed mild skeletal Class III relationship, so the amount of IPR was bigger on the lower arch than on the upper arch.
  • Patient was advised to wear each step of aligners for one week.
  • She was a very good and cooperative patient.
  • After the first set, the upper and lower crowded dentition was aligned well, and the crossbite was corrected.
  • For the occlusal improvement and upper incisor axis correction, an additional aligner of 14 steps was made.
  • After the additional aligner set, the upper and lower dentition showed a well-aligned and coordinated relationship.
  • The upper and lower midline was harmonic with the facial midline.

The patient and her parents were very satisfied with the Invisalign treatment results.
