Comments

  • The challenge with this treatment was to correct occlusal cant by intruding posterior Q1 teeth.
  • Extruding posterior q2 teeth, closed then the anterior and posterior open bite.
  • Also, this movement allowed a counterclockwise mandibular rotation.
  • The procedure solved a Cl II skeletal relationship, as can be seen in the final patient profile.
