Bruxism - the grinding and clenching of teeth

Bruxism affects over 50% of the population, and can be debilitating for many sufferers. However, despite being prevalent throughout the UK and worryingly on the rise, bruxism often remains overlooked and underdiagnosed. Whilst, for some, bruxing doesn’t cause any serious symptoms, for many – the habitual bruxers - the side effects are painful and persistent, and include headaches, migraine on waking and many more.

The Sleep Clench Inhibitor - SCi & SCi+

Previously known as NTI-tss, the SCi is the most clinically effective FDA approved treatment for TMD, bruxism, and medically diagnosed migraines. With excellent clinical results, SCi and SCi+ are proven to relieve patient symptoms.


How does the SCi work?

In a study by Clark GT et. al, tension-type headache patients without signs or symptoms of TMD clenched their jaws during sleep, on average, 14 times more intensely than asymptomatic controls. Moreover it has been shown, that temporalis contraction is twice as intense during sleep than in waking patients.

The SCi reduces parafunctional intensity of the temporalismasseters and to a degree, the lateral pterygoids (the tiny muscles at your jaw joints that open your jaw), eliminating posterior and canine contact thereby reducing temporalis clenching.

Try it yourself

Take a pencil and place it between your molars or canines. With your hands, feel the temporalis muscle bulge in the temple area.Then transfer the pencil between your incisors and palpate the temporalis at the same spot on your temples again: do you feel the difference?

Studies show that the possible contraction intensity of the temporalis muscle when only the incisors occlude is reduced by an average of 70%!

Indications for SCi

All cases requiring a disconnection of the occlusion and/or the relaxation of the masticatory musculature, such as:

  • the prevention of symptoms associated with bruxism

  • the treatment of certain types of TMD

  • the prevention of occlusal trauma, e.g. protection of restorations and implants in cases of severe bruxism

  • the prevention and treatment of chronic tension type headache and migraine pain

Advantages of the SCi

  • Excellent clinical results

  • Extremely simple and fast chairside procedure: fabrication in 20 minutes; no delays or lab fees

  • Excellent patient acceptance and compliance

  • High diagnostic value

  • Scientifically proven efficacy

Fitting and adjusting the SCi

The SCi is designed to be made chairside, though we also have the SCi+ that is an in-lab made version.

Designed to be quick yet effective, the SCi is simple to make and typically takes 10-15 minutes to ensure it is correctly fitted.

Your patient should test the device with their tongue to ensure they cannot remove it easily.

Watch our short fitting demonstration to see just how easy it is. If you'd like to know more, just give one of our technicians a call.

Clinical Testimonials

Dr. Pav Khaira, Red Sky Dental Spa and founder of the Migraine Care Institute

"The SCi - Chairside Splint system and the SCi+ laboratory made splints have become such an integral part of my everyday dentistry as much as it part of my more complex treatments. The results I have been getting are just amazing, recently I've resolved migraines in a lady who'd suffered with them for 30 years. The SCi is a cornerstone in my dental practice."


Dr. Andre Hedger. BDS. LDS. RCS. (Eng) FHS., Private GDP and Secretary of the British Society for the Study of Cranio- Mandibular Disorders.

This not a cure for TMD but significantly reduces symptoms and is definitely one step better than a normal bite guard as it reduces muscle clenching. There is no better method on the market to switch off chronic bruxing. This treatment increases patient loyalty because you've provided something for them that's improved their lifestyle by reducing or eliminating some of their chronic symptoms. The market is huge and unexploited."
