Results achieved

  • Class I relationship maintained
  • Functional canine guidance on both sides
  • Normal overjet and overbite achieved
  • 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 linewas achieved
  • All treatment goals were achieved case
  • Harmonic arches were achieved

Comments

  • The desired treatment outcome was achieved through a combination of sequential distalization of the posterior in the upper left quadrant and mesialization of 1.4 in order to create space for the eruption of the transposed 1.3
  • The curve of Spee was leveled in the lower arch with the intrusion of the lower anterior
  • Class II elastics were added for anchorage during the distalization process
  • While leveling the curve of Spee we used lingual root torque on the lower incisors for control of the root inclination
