Comments

  • We distalized the upper teeth with the use of Class II elastics
  • Upper and lower arches were expanded
  • IPR was performed on lower, to help resolve crowding and correct premolars rotations
  • We extruded upper and lower teeth to close the bite
  • I chose not not to correct the lower midline for the following reasons:
  • The upper midline follows the facial midline
  • The lower dental midline deviates 0.7 mm to the right side, but is not exposed in facial repose and smile photos
  • a Solid class I occlusion was achieved in both canine and molar region '
  • a Good OJ and OB was achieved in the anterior area
  • No aesthetic or functional reason was found for lower midline correction
  • The patient was highly satisfied with her treatment results
