Tongue posture

A simple recap of the major points about physiological position:

• the tongue must be in a high position, with its tip and dorsal part in contact with the palatine papillae; in this way the activity shown on the electromyography is minimal,
• presence of a free space in the molar area,
• lips are flexible and connected.

In a pathological position:

• the tongue is in an interdental or addental position,
• the free space in the molar area is increased,
• the lips are not connected and "fall open" (MAURIN).

This position, which is associated with functional problems, increases the likelihood of dento-maxillary abnormalities.
