2.3.4. Tongue Pressure
incisors, palate
TONGUE, CAVITY
Tongue pressure was measured using the JMS tongue pressure monitor TPM-01 (JMS Co., Ltd., Hiroshima, Japan). A tongue pressure probe was inserted into the oral cavity, and the base of the probe was lightly cupped by the upper and lower incisors to fix the mandible. The probe was fixed between the anterior part of the tongue and hard palate, and the patient’s tongue was pressed against the probe as hard as possible (maximum tongue pressure value). The maximum tongue pressure (MTP) was measured twice, and the larger value was used as the maximum value.
