DUARTE, Mario Sergio. The Modified Quad-Helix appliance in tongue rehabilitation of anterior open bite cases. Rev. Assoc. Paul. Cir. Dent. []. 2013, 67, 4, pp. 292-297. ISSN 0004-5276.

The open bite treatment is always a great challenge for the clinician, especially when the long-term stability factor is taken into consideration, because in most cases, individuals who present this type of malocclusion are affected lingual dysfunction, which, if not corrected satisfactorily, will be the factor of anterior open bite relapse. Thus, this paper aims to present a variation introduced in the original design of the Ricketts Quad-Helix appliance, which allows obtaining excellent results in the rehabilitation of the tongue during his peristaltic movements, as well as serving as a guide to its rest position.
