tongue habits results in anterior open bite or they can develop as secondary to thumb sucking. Many orthodontists have had

the patient had a tongue thrust swallowing pattern. Treatment approaches must incorporate interception of habit and correction
of the malocclusion. The case report explicates a modifi ed quad helix appliance used effectively into intercept tongue thrusting

and more patients accommodating.
