Results achieved

  • Class I relationship achieved
  • Functional canine guidance on both sides
  • Posterior crossbite corrected
  • Deepbite improved
  • Overjet improved
  • Midlines coincident
  • Proper axial inclination of incisors
  • Curve of Spee leveled
  • Arches aligned and coordinated
  • Alignment of both arches through derotation
  • Arch form improved
  • Aesthetic smile line¬†was achieved¬†
  • All treatment goals were achieved case
  • Harmonic arches were achieved

Comments

  • In the upper arch expansion + derotation of canines and incisors with sequence of derotation, I included in sequence of round tripping to make it more predictable.
  • After derotation IPR + intrusion + retrusion + palatal root torque.
  • In lower arch expansion + derotation of premolars to open space necessary for correction of whole crown crossbite (scissor-bite) of teeth 1.4, 4.4. Proclination + intrusion of lower incisors together with expansion and derotation of lower canines (rotated by 50 degrees).
  • With the sequence of round tripping of lower incisors and canines and integration of rotation at the same time, I de-rotated lower incisors and canines.
  • After derotation followed intrusion + retrusion + lingual root torque.
