NTI-tss™ Plus

The NTI is the only FDA cleared dental appliance for the treatment of migraine pain and associated tension headaches. NTI is a product made exclusively at NDX. By reducing muscle contraction intensity during parafunctional activity the NTI-tss Plus™ minimizes tooth wear, reduces joint strain and disc load, and decreases muscle tension leading to less migraines and morning headaches.

NTI-tss Plus™ Daytime

The NTI-tss Plus™ Daytime is a reduced version of the NTI-tss Plus™ that combines a lower profile with a targeted design for habitual daytime clenchers. A smaller Discluding Element separates the posterior teeth and canines in centric, allowing for a reduced vertical. However, due to its design, the NTI-tss Plus™ Daytime is not effective in excursions and should not be worn at night.

Indications:

  • Migraine or severe headache patient needing daytime therapy for muscle relaxation and pain relief.
  • A “habit” appliance for daytime bruxer or clencher.

Contraindications:

  • May adversely affect speech or appearance for some patients.

Advantages:

  • Smaller Discluding Element is less obtrusive and noticeable for daytime wear
  • Smaller span due to less required retention during daytime use
  • Minimal vertical opening
