评论

  • This young lady has a narrow arch with an anterior open bite.
  • Her skeletal Class II was improved in the treatment due to the autorotation of the mandible and correcting the anterior open bite.
  • The major mechanics in Invisalign treatment is molar intrusion and a vertical jump to simulate the automation of the mandible.
  • Arch expansion in Invisalign was excellent to the jump achieved at the end of treatment
