评论

  • This is a Class II div1 malocclusion with large overjet, deep bite and lip protrusion case
  • We created space in the upper arch space with the extraction of the 1.4 and 2.4
  • Spaces were closed with maximum anchorage.
  • We created space in the lower arch with the extraction of the 3.5 and 4.5 to achieve Class I
  • Due to poor compliance during the initial aligner treatment, we still had a posterior open bite and molar mesial tilting
  • After the 2nd refinement we were able to improve the patient's profile and finish with an ideal occlusion
