The Nociceptive trigeminal inhibition tension suppression system (abbreviated to NTI-TSS , or NTI-tension suppression system ), is a type of occlusal splint claimed for preventing headaches and migraines by reducing sleeping bruxism (teeth and grinding day teeth). Sleep bruxism supposedly leads to trigeminal nerve hyperactivity, often triggering a typical migraine event. Hyperactivity of trigeminal neurons during trigemino-nociceptive stimulation is the cause of the proposed migraine and correlates with imaging of migraine sufferers. The goal of NTI-TSS is to relax the muscles involved in clenching and curling, thereby reducing the chances for migraines and tension headaches to develop through the reduction of nociceptive stimulation that is usually caused by parafunctional activity. Sometimes used for temporomandibular joint dysfunction (TMD).
The NTI-TSS is a small transparent plastic device that, in its most widely used form, is worn in front of four teeth, both curved, at night, and is intended to prevent contact of canine teeth and molars. Usually installed by dentists who are trained in engineering, and built by dental laboratories.

Evidence and security
Since NTI-TSS does not cover all the teeth, it is classified as partial occlusal splint closure. The partial coverage of splints is recommended by some experts, but they have the potential to cause undesirable tooth movement if used 24 hours a day 7 days a week without untargeted (never recommended) teeth, which rarely can be severe. Because patients can not use NTI-tss devices while chewing food, the posterior alveolar structure receives daily stimulation every day, therefore, there is no chance for functional adaptation of the occlusal scheme, ie tooth supra-eruption. Research shows that the alveolar bone requires at least 8 days of lack of stimulation before bone growth in the apex (supra-eruption) can begin. The periodontal ligament that surrounds the roots and holds the teeth in place - if the ligaments are stimulated (held) then it will continue to hold the teeth in the correct position.
As for the anterior intrusion, the lack of continuous apical force does not provide sufficient opportunity to disrupt the incisors. The 2010 review of scientific studies conducted to investigate the use of occlusal splints in TMD concludes the following with anterior bite equipment (another term for partial occlusal splints covering only the front teeth):
"Other types of equipment, including [...] anterior bite equipment, have multiple RCTs (randomized controlled trials) evidence of efficacy in reducing TMD pain.However, the potential for side effects with these devices is higher and indicates the need to close. its use. "
