American Board of Orthodontics (ABO) Practice Exam

Question: 1 / 660

What is one long-term effect of Class II elastics compared to functional appliances?

Greater skeletal changes

Significantly diminished skeletal changes

Long-term effects of Class II elastics are characterized by their ability to produce dental changes rather than skeletal changes. While functional appliances are designed to encourage skeletal adaptations by modifying the position of the mandible and influencing growth patterns, Class II elastics primarily work by pulling the maxilla back and the mandible forward through the dental occlusion.

Over time, this results in improved dental occlusion but does not significantly alter the skeletal structures. Consequently, the long-term treatment outcomes from Class II elastics often show diminished skeletal changes compared to the more pronounced effects associated with functional appliances. This difference is critical in understanding treatment options when addressing Class II malocclusions and the role of various appliances in orthodontic treatment plans.
