What is the Science behind Aligner Attachments/Engagers?

Despite the widespread utilization of aligner attachments/engagers, there is relatively little evidence for their efficacy in the scientific literature. The topic is further complicated by the diversity of clinical opinions regarding their use and effectiveness. Some clinicians use attachments/engagers on almost all the teeth while others use none at all.

This presentation will focus on the evidence for using attachments and provide insight regarding key tooth movements where they are required and review the relative effectiveness of the various designs. The goal of this presentation is to provide quality information to participants so they can make effective decisions regard use of attachments in their aligner treatments.

1. Learn about the basic aligner attachment/engager designs.
2. Understand how the various designs deliver biomechanical forces.
3. Know the relative efficacy of the various attachment designs for specific tooth movements.
4. Learn about effective tooth movements without the use of attachments/engagers.
