Total Treatment Time

  • 22 months

Number of aligners

  • Maxillary: 34

Retention

  • Maxillary: Bonded lingual wire (33-43) and removable retainers
  • Mandibular: Bonded lingual wire (12-22) and removable retainers

Results achieved

  • Class I relationship was achieved through favorable mandibular growth both anterio-posteriorly and slightly vertically enhanced with good class 2 elastic wear.
  • Upper anterior teeth aligned and level
  • Mild upper crowding was resolved.

Comments

  • Interesting treatment as patient presented with a full class II, skeletally based malocclusion
  • Treatment options typically considered, would be either a 2 phase approach of functional orthopedics, followed by braces, or a single phase treatment of braces with class 2 elastics
  • I elected a similar approach, but utilized Invisalign Teen with class 2 elastics
  • This treatment was successful because it was likely to be the favorable growth pattern and staging, combined with excellent patient elastic and aligner wear compliance
  • I would alter 2 things in a future similar case
  • I would use a full class II elastic –correction simulation in the patient Clincheck set up.
  • Class II elastics from buttons 1.3 (UR3), 2.3 (UL3) and 3.6 (LL6), 4.6 (LR6)would be more beneficial in overbite and incisal height corrections.
