코멘트

  • Resolved the crowding with upper anterior expansion and lower anterior labioversion.
  • Resolved the crowding-making space by expanding the deciduous molars.
  • Acquired the space by adjusting the distal rotation of deciduous posterior teeth and 1st molar.
  • Achieved the overbite with relative intrusion by intruding the upper/lower anterior teeth and extruding the premolar/molar. The Precision Bite Ramps helped in this case.
  • Achieved the overjet with a retraction by the expansion of canines, premolars, and anterior protraction.
