Is an E arch a fixed or removable appliance?

Explanation:
An E arch is a fixed appliance. It is attached to the teeth (usually with bands on the molars) and connected by a wire that remains in the mouth for the duration of treatment. Because it is cemented/banded in place and not removable by the patient, it delivers continuous, clinician-controlled forces on the teeth, independent of patient cooperation. This is what differentiates it from removable appliances, which patients take out and wear as instructed.
