Elastics are used to move all of the upper teeth against all of the lower teeth. If Dr. Trosien has asked you to use elastics, it is very important that you are able to wear them.
"Triangle" elastics are used to close the bite down in front. They hook up to the farthest forward hook on the upper and the farthest forward 2 hooks on the lower.
"Class 2" elastics are used to pull the upper teeth back against the lowers (to correct an overbite). They hook up to the farthest forward hook on the
upper and the lower molar hook.
"Class 3" elastics are used to pull the lower teeth back against the uppers (to correct an underbite). They hook up to the farthest forward hook on the lower and the molar hook on the upper.
