ONIRIS® is an innovative and patented mandibular advancement device designed to bring you maximum comfort and effectiveness. It is a device – similar to a sports mouthguard or a dental tray- that gently holds the lower jaw in an advanced position while sleeping. It thus keeps the air passage at the pharynx open and prevents the obstruction phenomenon that causes snoring and sleep apnoea. Numerous clinical studies show that this technique works. ONIRIS® is the only one to offer a custom-made impression that can be re-fitted several times and total freedom of movement that allows quick, comfortable and efficient adaptation.

Yes, and because you ask for more than just promises, we offer results!

The ONIRIS® mandibular advancement device is the first self-adapting anti-snoring device to have been tested in many hospitals and clinics by sleep specialists, ENT specialists and dentists in France. It has demonstrated an effectiveness and comfort level equivalent to custom-made oral devices made in dental laboratories, which cost hundreds ofpounds. These rigorous tests ensure that what we promise is a reality:

You have evidence not promises (1).

[1] Prospective multi-centre open, uncontrolled study carried out within the Assistance Publique-Hôpitaux de Paris [university teaching hospital] with the main objective of evaluating the effectiveness of the ONIRIS thermoformed mandibular advancement device in 41 patients suffering from snoring and severe sleep apnoea syndrome, who are refusing or abandoning CPAP. The duration of follow-up was 45 to 60 days, controlled by an independent laboratory based on a protocol validated by the AFSSAPS [French Health Products Safety Agency], the Institutional Review Board Sud Med IV, the CCTIRS [Advisory Committee on Health Research Information Processing] and the CNIL [National Commission for Information Technology and Civil Liberties].

Tell your dentist that you are wearing a mandibular advancement device and if your teeth change a lot, check with him/her that you can still wear the ONIRIS® oral device.

This does not usually pose any problems. However, we advise you to ask your dentist whether these appliances are of good quality and not fragile.

Yes, for several decades clinical studies have shown that mandibular repositioning devices are effective against snoring and sleep apnoea. There are of course other treatments.

This is why mandibular advancement devices are generally recommended as the first treatment to try to combat snoring and sleep apnoea [1] by the American, European and Japanese Academies of Sleep Medicine.

But for a mandibular advancement device to work, it is essential that it combines several characteristics:

  • A high-precision dental impression to avoid dental pain and movement.
  • Precise advancement adjustment from 0 to 11mm for maximum effectiveness and comfort.
  • Total freedom of movement allowing you to breathe naturally, drink or talk.
  • Easy to use, can be repeated and readjusted if necessary for more comfort.

ONIRIS is the only over-the-counter anti-snoring oral device to bring together all these features to give you a quality, comfortable and restful night’s sleep.

[1] In the case of mild to moderate sleep apnoea. In case of sleep apnoea, mandibular advancement oral devices are recommended in case of refusal of or in combination with positive pressure ventilation machines. In case of sleep apnoea, ask your doctor for advice.

Surgery can be effective but it is very expensive, presents risks and does not guarantee results even though it is definitive. Ventilation masks are effective but restrictive and are reserved only for severe cases of sleep apnoea. Nasal dilators can help some snorers if nasal breathing is limited, but this is not the main cause of snoring. And throat lubricants (sprays or lozenges) don’t work for more than a few minutes and on very light snoring.
