How are elastic SEPs used in orthodontics?

In orthodontics, elastic separator devices, often referred to as SEPs, play a significant role in the process of creating space between teeth to facilitate the placement of bands. They are specifically designed to stretch and create a gap between adjacent teeth, which allows for the proper fitting of orthodontic appliances.

While the question focuses on the application of elastic SEPs, choice C suggests that they are "not applicable," which is incorrect because elastic separators are indeed relevant in orthodontic procedures.

The correct function of elastic separators includes seating bands and preparing the mouth for braces, which are essential steps in orthodontic treatment. Thus, elastic SEPs are definitely applicable when discussing their role in orthodontics.
