NTI
Tension Suppression System
The most effective FDA-approved method of
migraine prevention
|
"NTI"
refers to the nocturnal inhibition of trigeminal nociception.
During
unprotected nocturnal parafunction, massive amounts of noxious input
(called nociception) bombard the trigeminal sensory nucleus .By
keeping the molars and canines from touching, the method of generating Nociception
to the Trigeminal is Inhibited. (so it's not the presence of incisal contact that is
therapeutic, but the absence of posterior and/or canine contact)

Migraine:
A Disorder of the Trigeminal Nerve
The trigeminal nerve gets
its name from its three divisions, each having specific
responsibilities. The
first two divisions (I and II) are primarily responsible for reporting
sensations
back to the brain (called “sensory” nerves). The
“busiest” is the third division (III),
which provides sensations
from everything below the cheekbone, including teeth, lips, gums, and
the jaw
joint.
|
In migraine, the main center
for sensation reception (called the “sensory nucleus”) has become
hyper-sensitized and responds unfavorably to normal outside stimuli. Part of the response to the stimuli (commonly
known as “triggers”) can be chemical secretions (primarily CGRP) that
irritate and inflame
arteries surrounding the brain (resulting in migraine pain) and within
the
sinuses (resulting in pain, stuffiness and discharge, or “sinus
headache”).

of Migraine

Until recently,
the third division had been
ignored as a possible contributing factor in migraine.
In a large
percentage of migraine sufferers, the
motor root which travels within the conduit of the (sensory) third
division is hyperactive, commanding tremendous
amounts
of potentially damaging activity from the jaw muscles during sleep. This results in a bombardment of noxious
(negative)
information going back to the sensory nucleus, thereby
sensitizing it, making the patient far more susceptible to
migraine attacks.

Preventing migraine
at its source…
without drugs.

The NTI
device reduces trigeminal motor hyper-activity and the resulting
noxious sensations back to the trigeminal nerve.

Want proof?
Feel
how it works.
While
touching the muscles
of your temples (at the X’s below), bite down on a wooden pencil with
your back
teeth as hard as you can. You’ll feel
the muscle bulge as it intensely contracts. Now
compare to when biting on the pencil with
your front teeth only. That’s how the
NTI device works.
