Remedial therapy based on restoring the balance of the oral muscles.
Myofunctional therapy is a remedial therapy based on the recovery of the imbalance in the functioning of the oral muscles. In general, abnormal oral habits cause an imbalance between the oro-facial muscles. This imbalance can lead to an abnormal physiognomy and morphology.
For example, dysfunctional oral habits like mouth breathing, thumb sucking, etc. in combination with an abnormal swallowing habit can lead to a strong protrusion of the upper front. The tongue thrusts the front buccal elements forward. The lips, which are not closed in case of mouth breathing, do not exert any counter pressure.
In this case, the incorrect use of the muscles and the absence of counter-pressure will lead to an abnormal shape of the jaws and/or teeth. The functional malocclusion is a fact. If it has to be changed, it is obvious that the function of the muscles involved should be changed first.
A multidisciplinary approach is therefore desirable for a lasting result. Dentists and orthodontists deal with the shape and morphological abnormalities of the teeth and speech therapists deal with the function of the oro-facial muscles.
