Comments

  • Invisalign orthodontic treatment of molar distalization is appropriate as long as there is enough space in the distal area of the second molar.
  • In cases of moderate crowding, if the side profile is good, the patient's oral volume is small, and the tongue bite marks are obvious, the crowding can be relieved by IPR and distal molar movement.
  • Paid attention to anchorage control during Invisalign treatment.
  • After the treatment, the upper and lower teeth were neatly arranged, the occlusal relationship is very good, and the facial shape is maintained.
