Innovative and Patented

Oniris is an innovative and patented Mandibular Advancement Device (MAD) designed to provide maximum levels of comfort and efficacy. The device is similar to a mouthguard for sportsmen or a dental splint and gently retains your lower jaw in a forward position during sleep. Once in place, the device allows air to pass freely through the throat, preventing the obstructions that cause snoring and Sleep Apnoea.

Numerous clinical studies have shown that this technique works. Oniris is the only solution to offer patients a customised fitting and total freedom of movement for a comfortable and effective adjustment.

In addition, Oniris is the first – and only – thermoplastic (heat and bite) MAD that is non-inferior to custom-made devices1.


How it works

Oniris includes two sizes in every pack. It is advised that you start with the small size, and in the event this is too small, try the larger device. Each Oniris MAD has an average lifespan of between 12 and 24 months, making it one of the most cost-effective Sleep Apnoea therapies over its lifespan. The device can also be remoulded up to 5 times – a useful function if you are undergoing dental work.

The device has nine adjustment settings. Starting with 0 – when you take the impression. Advancement then starts with position 1. If you are new to mandibular advancement, it is advised that you wear the device for short periods throughout the day before wearing it for a full night of sleep. Your jaw and teeth will need time to adjust, and a slow introduction can reduce the chance of tooth and jaw discomfort.

Once you are happy and comfortable with position 1, you move up to position 2 and so on until you reach a level of advancement which is suitable for you. Advancement options are from 0 to 11mm.

Clinically Proven

The Iris Clinical Study is the largest randomised controlled study in the field of Mandibular Advancement Devices and included 200 patients who were all refusing or not tolerating CPAP. These patients had an average AHI of 26.6/h.

  • 1 year of follow-up in 7 different facilities
  • In Intention-To-Treat (ITT) and Per-Protocole (PP) analysis

To determine whether Oniris thermoplastic heat-moulded titrable MAD is non-inferior to a custom-made MAD for Obstructive Sleep Apnoea (OSA) in terms of effectiveness, compliance and tolerance.

  • The non-inferiority of Oniris MAD is confirmed regardless of the analyzed population (ITT or PP),
    gender, BMI or OSA severity.
  • Good or excellent compliance for 89.7% of patients at 2 months and for 93.1% at 12 months.
  • No significant dental or joint impact was observed in more than 96.6% of patients after 1 year
    of treatment.
  • Publication: The results of the IRIS study were published in the scientific journal


94 % of users satisfied or very satisfied2
83 % of full efficiency on snoring2
77 % of full efficiency on Sleep Apnoea2


Case Study

Habitual snoring occurs in around 44% of males and 28% of females between ages 30 and 60; however, not everyone who snores has a sleeping disorder like Obstructive Sleep Apnoea (OSA).

This device is clinically tested and proven to help reduce or eliminate snoring and can help reduce the symptoms of mild and moderate Sleep Apnoea. We asked a customer whose snoring had progressively worsened over the last six months to document their experience using the Oniris MAD.
