Comments

  • This is a Class II div2 subdivision case combined with facial asymmetry.
  • The patient wanted a better smile and asked for correction of her gummy smile, deep bite, crowding and rotated teeth.
  • Due to her good lateral profile, I decided to do a treatment without extraction.
  • I designed sequential distalization over Q2, with an elastic jump at the end to correct Class II to Class I over L't side.
  • Gummy smile and deepbite are corrected by intrusion of upper and lower incisors.
  • 2.4 Rotation is corrected with optimized rotation attachment for 60 degree rotation.
  • L't side Class II elastics for anchorage and elastic jump.
  • Total Tx time is 20M.
