Insights to Migraine
Jaw clenching muscles of migraine suffers are 70% larger in volume and generate significantly higher bite forces than control subjects. (muscles enlarge and strengthen resulting from habitual intense exercise) (1,2)
Migraine sufferers who experience headaches soon after or upon waking show significant evidence of nocturnal jaw clenching (3).
Pericranial tenderness (soreness of the muscles of the scalp upon palpation) is present in every migraine and tension-type headache sufferer, while absent in controls (4) . (Pericranial tenderness results from over work of a muscle, i.e., jaw clenching during sleep)
Tension-type headache patients contract their temporalis muscles (clench their jaw) during sleep, on average, 14 times more intensely that asymptomatic controls (5).
Simple minimal voluntary jaw-clenching (of less than 30% of maximum effort) for 30 minutes (with two rest periods) still results in a headache for 63% of migraine sufferers (6) . Jaw clenching during sleep can frequently exceed voluntary maximum (7) .
A traditional dental mouthpiece can allow for clenching intensity and resultant symptoms to perpetuate or intensify (8,9).
A device which prevents molar and canine tooth contacts reduces clenching intensity to 1/3 of maximum (10).
The NTI-tss, which prevents molar and canine tooth contact while being worn
during sleep, provides a 77% average reduction in migraine pain episodes for
82% of migraine sufferers (11).
