Treatment summary

Results Achieved

  • Class I relationship maintained
  • Functional canine guidance on both sides
  • Anterior crossbite corrected
  • Normal¬† overjet and overbite achieved
  • Proper axial inclination of incisors
  • Curve of Spee leveled
  • Aesthetic smile line¬†was achieved

Total treatment Time

  • 24 months

Number of aligners

  • Maxillary: 46 + 7 = 53
  • Mandibular: 37 + 13 = 50

Aligner wear time

  • 7-10days

Comments

  • This patient had a protruded lateral profile that we wanted to improve
  • We planned to extract all the first premolars and retract the upper and lower anterior teeth.
  • his patient has moderate periodontitis with moderate gingival recession and alveolar bone resorption, which lead to the long clinical crown
  • Therefore the retention is better and anchorage control and anterior torque control easier than patients with short clinical crowns
  • G6 optimized attachments were applied on all the quadrants except lower left
  • G6 optimized attachments are a good solution for first premolar extraction cases

Retention

  • Maxillary: Vivera
  • Mandibular: Vivera
