Total treatment Time

  • 18 months

Number of aligners

  • Maxillary: 46 + 23 = 69
  • Mandibular: 32 + 19 = 51

Aligner wear time

  • 1-week

Comments

  • This is a class I malocclusion case with anterior crowding and crossbite
  • Both upper and lower incisors flare out and create a protrusive profile.
  • The plan was to do extraction on 1.4,2.4,3.5,4.5  to resolve crowding, and some retraction for an improved profile.
