  • Alignment of both arches through derotation
  • Arch form improved
  • All treatment goals were achieved case
  • Harmonic arches were achieved

Comments

  • Achievement of proper Class I buccal relationship with concurrent improvement of the overjet was achieved by sequential distalization of the upper posterior segments.
  • Class II elastics was worn throughout treatment for anchorage during distalization and also for enhancement of the buccal occlusion through the elastics effect.
  • Intrusion of the lower anterior segment was achieved through relative intrusion by a combination proclination and intrusion of the lower incisors.
  • Proclining the lower incisors also helped to expand the arch for relieve of crowding and subsequent improvement of alignment of the teeth.
