Results achieved

  • Class I relationship achieved
  • Functional canine guidance on both sides
  • Normal overjet and overbite achieved
  • Overjet improved
  • Significant improvement of overjet
  • Midlines coincident
  • Proper axial inclination of incisors
  • Curve of Spee leveled
  • Arches aligned and coordinated
  • Alignment of both arches through derotation
  • Arch form improved
  • Aesthetic smile linewas achieved
  • All treatment goals were achieved case
  • Harmonic arches were achieved

Comments

  • 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
