| 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).
