  • Aesthetic smile line was achieved
  • Harmonic arches were achieved

Total treatment Time

  • 10 months

  • Maxillary: 14 + 14 = 28
  • Mandibular: 14 + 14 = 28

Aligner wear time

  • 1-week

Comments

  • Posterior sectors expansion.
  • Torque correction mainly at the upper canines.
  • Dental and smile aesthetics improved significantly, due to the crowns and gingival zeniths leveling, as well as a decreased gingival exposure of the lateral/posterior sectors on the right side.
  • Harmonious smile, with a significant improvement of buccal corridors, that appear narrower due to the expansion of premolar and upper molar sectors, as well as the torque correction essentially at the superior canines level.
  • IPR to help solve the lower incisors crowding.
  • Anterior extrusion, to help correct the protrusive guide and smile improvement.
  • Considered the occlusal plane cant tipping down and to the right, the extrusion of the lateral and central upper right incisors.
  • In addition to the inverted smile line, these teeth were in a higher plane without gingival exposure
  • Digital Smile Diagnosis in order to minimize and avoid possible failures, considering the small margin of error with this treatment plan.
