An NTI-tss is a type of splint which the manufacturer claims to help in the prevention and treatment of bruxism, disorders where jaw movement is impaired, tension type headaches and migraine. Bruxism is a disorder where an individual grinds their teeth while sleeping. The following study reviews the current evidence supporting the effectiveness and safety of NTI-tts splint.

The authors searched on 9 electronic data bases and NTI-tts associated websites for all relevant articles. The authors discovered a total of 68 relevant publications. Of the 68 publications 9 reported the results of 5 different human studies. Two of the 9 studies used a technique called electromyography. This technique is used to record the electrical activity produced by skeletal muscles. The two studies compared an occlusal stabilization splint to a NTI-tss splint in patients with impaired jaw movement and bruxism or with bruxism alone. Both studies showed that the NTI-tss splint reduced electrical activity in skeletal muscles. Two other studies focused mainly on patients with impaired jaw movement. One of these studies reported that a stabilization splint was more effective than a NTI-tss splint. The other study reported no difference between the two devices. One study found that patients with tension-type headache or migraine responded better to NTI-tss than to a bleaching tray. The adverse effects caused by the NTI-tss splint were mainly linked to single teeth or to the occlusion.

Studies suggest that the NTI-tss splint may be used to manage bruxism or disorders related to impaired jaw movement. To avoid unwanted effects the patient has to commit to follow-up appointments. NTI-tss splint may be used in patients who want to reduce jaw clenching or tooth grinding or as an emergency device in patients with moderate pain from impaired jaw movement or restricted jaw opening.
