NTI appliance

NTI stands for Nociceptive Trigeminal Inhibition Tension Suppression System, which explains exactly what it does.

How does the NTI work?

The NTI is an FDA approved occlusal splint (nightguard) designed to reduce muscle tension headaches and migraines.  All the information one would ever be interested in can be found on their website here.  Here is some research

These are the muscles that are most effected by clenching and grinding

What are some of the symptoms that someone that would benefit from an NTI has?

Chronic symptoms of the head and neck can be attributed to the over-worked muscles involved in a clenching or grinding habit:

A) Headache — the temporalis muscle (it closes and clenches the jaw)

B) Sinus pressure and pain — the lateral pterygoid muscles (it moves the jaw side to side and/or forward)

C) Neck stiffness and pain — trapezius muscle (it stabilizes the skull during jaw clenching and grinding)
