A Single Versatile Appliance for Habit Interception and Crossbite Correction

الملخص EN

Digit sucking is a common childhood behavior, which has an adaptive value for children up to the fourth year of life.

It is usually associated with oral pleasure and self-comforting behavior.

But chronic practice may produce deleterious effect in the form of dental and skeletal deformities.

Adjunctive therapy using bluegrass appliance as a permanent reminder and quadhelix appliance as a reminder as well as a slow palatal expander has proven successful in intercepting digit-sucking habit and expanding the arch for crossbite correction.

In the present case, a versatile modified quadhelix appliance incorporating a roller was designed to clinically correct the habit and its resulting dentofacial deformities.
