Abnormal tongue positioning is associated with open bites as well as other aspects of malocclusions. Having correct tongue posture and activity are important aspects of successful orthodontic treatment and long term stability. With orthodontic treatment of open bites, the tongue’s environment is changed with the intent that tongue positioning will become normalized. With myofunctional therapy, training exercises are used to correct tongue positioning, which can then lead to improved structure of the mouth. While each approach can have positive treatment results, this presentation will focus on evidence related to treatment outcomes when both form and function are simultaneously addressed.
Comprehend the developmental relationship of tongue posture to anterior open bites.
Recognize potential limitations of orthodontic treatment if tongue function remains abnormal.
Appreciate the synergistic impact of combining orthodontic and myofunctional therapy in achieving long term success when correcting open bite malocclusions.
