NTI-tss Plus™

NTI is a 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 fewer 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.
