Comments

  • This was a Class II case with the need for good vertical control
    The Invisalign treatment was ideal for this case because the aligners and bite force aided the intrusion of the posterior teeth
  • We used the G6 SmartForce features on the maxillary teeth and G5 SmartForce features on the mandibular teeth
  • The lateral appearance was significantly improved
  • All the patient's complaints were resolved

Retention
