Orofacial Myofunctional Therapy
What is Orofacial Myofunctional Therapy?
(IAOM webpage, 2019). Orofacial Myofunctional Disorders are atypical, adaptive patterns that emerge in the absence of normalized patterns within the orofacial complex. The regular presence of these adaptive movements can often result in a variety of disturbances.Examples of Orofacial Myofunctional Disorders include one or a combination of the following:
- Thumb and finger sucking habits
- A routine habit of resting with the lips apart
- A forward resting posture of the tongue between or against the teeth
- Tongue Thrust
- Other harmful oral habits
Orofacial Myofunctional Disorders are often related to, or can contribute to a variety of medical and dental disorders. These disorders can include:
- Malocclusion (improper alignment of the teeth)
- Periodontal disorders
- Orthodontic relapse
- Changes associated with abnormal jaw growth and position
- Therapeutic intervention can involve the selection of appropriate oral tools such as straws, lip or bite blocks, appropriate food items, etc. for jaw-lip-tongue dissociation needed for eating and drinking.
- Techniques for handling and swallowing of saliva, liquids and solids
- Oral resting posture activities
- Labial-lingual-pharyngeal muscle resistance exercises
- Exercises to improve lip closure may include holding a tongue depressor between the lips (Ray, 2003), use of a lip gauge (Paskay, 2006), smiling widely and then rounding lips alternately (Meyer, 2000), and lip resistance activities (Satomi, 2001).
- Exercises to improve tongue, lip, and jaw differentiation include oral tactile stimulation and tongue movements without assistance from the jaw, such as tongue tip to alveolar ridge or tongue clicks against the palate (Meyer, 2000). Isotonic and isometric exercises target the lips and tongue, in order to teach closed mouth resting posture and nasal breathing
