Interceptive elastics in mixed dentition are used to correct bite relationships by applying forces between arches to guide eruption. Which option best represents this use?

• A. They apply corrective forces between arches to guide eruption and correct posterior crossbite or bite mismatches
• B. They whiten teeth
• C. They have no role in mixed dentition
• D. They only affect aesthetics

Answer: (A)

Interceptive elastics in mixed dentition work by applying forces between the upper and lower arches to influence how teeth erupt and how the bite develops. These cross-arch forces guide erupting teeth into a more favorable path and help correct bite relationships, especially posterior crossbite where the upper arch is too narrow compared with the lower. By directing eruption and, when needed, widening the maxillary arch, they promote a more harmonious occlusion as permanent teeth come in, reducing the need for later, more extensive treatment. They aren’t about whitening, and they do have an important role in mixed dentition, not just aesthetics.
