Comentários

  • This is a Class III spacing case.
  • When we close all lower anterior spaces, the negative overjet (aka anterior crossbite) will be resolved.
  • But according to the very thin symphysis, retraction of lower anterior teeth needs to be done carefully to prevent labial tipping of the root that causes dehiscence.
  • The power ridge feature of the Invisalign system is very effective to control root torque during retraction of lower anterior teeth.
  • We could notice that only lower incisors crowns were retracted while the roots were still in the bone.
