Description: The NTI appliance fits on the upper front teeth and is designed to prevent tooth clenching and grinding. The objective of the NTI-TSS is to relax the muscles involved in clenching and mastication, thus supposedly diminishing the chances for migraines and tension headaches to develop. It is sometimes used for temporomandibular joint dysfunction (TMD).

Indications: However, because it fits on only a few teeth, it places a great deal of stress on them and that can be harmful. Also, because of its small size, if it comes off during the night, there is danger that it could be swallowed or aspirated.

Insertion: Patients can remove and reinsert
