코멘트

  • Upper sequential distalisation and arch expansion were adopted for midline correction and molar class improvement.
  • Staged intrusion for the lower anterior was very effective in reduction of 2 mm overbite and leveling of the excessive curve of Spee.
  • With early use of Class II elastics, this case was finished with 30 aligners and 8 additional aligners.
  • Upper incisor inclination was improved, midline was coincident, and full Class I canine /molar relationships were achieved after treatment.
