Orofacial Myofunctional Disorders (OMDs) are disorders of the muscles and functions of the face and mouth. OMDs may affect, directly and/or indirectly, breastfeeding, facial skeletal growth and development, chewing, swallowing, speech, occlusion, temporomandibular joint movement, oral hygiene, stability of orthodontic treatment, facial esthetics, and more.
Most OMDs originate with insufficient habitual nasal breathing or with oral breathing. The subsequent adaptation of the muscles and the orofacial functions to a disordered breathing pattern creates many OMDs. Certain habits or conditions can interfere with proper actions of orofacial muscles causing OMDs. These muscles include cheeks, jaw, lips and tongue. When these muscles function incorrectly due to habits or conditions, it can lead to improper development. This is a typical development causes the muscles to have incorrect adaptations and not work in balance, which can cause a variety of problems.
