Comentários

  • Invisalign is good for molar distalization and intrusion of lower front teeth.
  • The upper posterior teeth were distally moved by 1mm.
  • Class II elastics were used in the first phase and MA was used in the next two phases to correct mandibular retrognathia and help retract upper incisors.
  • The upper and lower arches were expanded by 1mm per side at the posterior and canine areas.
  • The lip posture was much better after correction of deep bite and retraction of upper front teeth.
