Interceptive elastics in mixed dentition are used to what?

Interceptive elastics in mixed dentition are used to what?

• A. They apply corrective forces between arches to guide eruption and correct posterior crossbite or bite mismatches, leveraging growth potential
• B. They whiten teeth
• C. They have no role in mixed dentition
• D. They only accelerate root growth

Answer: (A)

Interceptive elastics work by creating interarch forces that influence how erupting teeth align and how the bite develops during growth. In mixed dentition, the jaws are still growing and teeth are erupting, so applying elastic forces between the upper and lower arches helps guide eruption paths and correct bite relationships as they form. These elastics can help settle a posterior crossbite and balance bite mismatches by directing eruption and encouraging proper maxillary expansion or mandibular positioning, taking advantage of the body's growth potential to set up a more favorable occlusion for the permanent dentition. They’re not about whitening, they do have a role in mixed dentition, and they don’t work by accelerating root growth.
