Comments

  • For patients with this kind of facial type, the extraction of four premolars and a small amount of mesial movement of molars can adjust the relationship between the molars and significantly improve the face type
  • In the process of using Invisalign the vertical transverse sagittal and torque can be well controlled to achieve final treatment results
  • We didn't correct the midline shift as this was not the treatment goal for this patient
