The GRAIL: Predictable Class II Correction with Aligner Therapy

‐ Feb 13, 2021 10:00am

Class II correction with aligner therapy is difficult, but there is a misunderstanding as to why. It is not difficult to plan treatment and hand out aligners, it is difficult to overcome the psychological barriers to patients wearing elastics when they do not want their orthodontic treatment to show. This difficulty is compounded by the inability to identify in advance which patients will wear elastics from those who will not. This leaves the orthodontist struggling with a patient who will not allow treatment to be completed without fixing the overjet, but who is unwilling to wear elastics to make the correction. Aligner therapy can be made more predictable (and enjoyable) if this dynamic is recognized, appreciated and if we can find ways to work around the trap. This lecture will explain the underpinnings of the psychology around “loss aversion” and present a creative way to correct Class II malocclusions predictably with aligner therapy.

Learning Objectives:

  • Comprehend the concept of “loss aversion” and how it impacts patients motivated by dental esthetics.
  • Evaluate how loss aversion undermines the use of elastics with clear aligner therapy making Class II correction problematic and unpredictable.
  • Gain new clinical techniques and protocols that make correction of Class II malocclusions more predictable with clear aligner therapy.
