The E-arch is used to widen the upper and or lower jaws to make room for permanent teeth. The appliance has two crowns or bands usually positioned on the baby molars or permanent 6-year molars. From the crown on one side is an L-shaped sleeve, and on the opposite side is an L-shaped arm which is attached to the opposing crown.
Between the two “arms” is a spring, which widens the arch by “gently” adding force.
The patient is seen about every 8 to 10 weeks. The arch width is measured and the spring is usually re-activated by adding “crimp stops” to hold the compressed spring in place. This appliance is very effective and requires little attention other than keeping it and the surrounding gums and teeth very clean.
