Orthodontic Assistant Practice Exam

An elastic separator is typically placed by doing what?

1. Only pushing through the contacts

2. Stretching and pushing through the contacts

3. Using scissors to cut it

4. Installing it within the molar region only

The correct answer is: Stretching and pushing through the contacts

Placing an elastic separator involves the technique of stretching and pushing it through the contacts between teeth. This method is effective as it allows the separator to expand within the interproximal space, creating the necessary space between the teeth for orthodontic purposes. The stretching action helps to properly seat the separator without damaging the adjacent teeth or gums. The other methods mentioned would not achieve the desired result. Simply pushing through the contacts might not provide enough force for proper placement, while cutting the separator with scissors is not a standard practice and can compromise its integrity. Additionally, installing it solely in the molar region does not consider the broader application of separators which might be needed in other areas to facilitate orthodontic treatment.
