What is used to connect multiple elastics in an orthodontic setup?

In an orthodontic setup, hooks or buttons are specifically designed to connect multiple elastics. These components serve as anchorage points for the elastics, allowing orthodontists to effectively apply force to move teeth into the desired position. By attaching elastics to these hooks or buttons, an orthodontist can create the necessary tension and coordination between different teeth, which is essential for achieving the intended dental outcomes.

Brackets, on the other hand, are primarily used to hold archwires and are bonded to the teeth, while archwires are the actual wires that connect the brackets and aid in the movement of the teeth. Separators are used to create space between teeth before placing bands, rather than for connecting elastics. This distinction highlights the specific role that hooks or buttons play in the orthodontic process, making them the correct choice for this question.
