MAD therapy for snoring and OSA
Some people struggle to adjust to CPAP therapy, even with a great mask and a well-designed device. For people with mild-to-moderate OSA or as a second intention for severe OSA patients, there’s a proven, effective alternative to CPAP1: the Narval appliance.
How does MAD therapy work
A mandibular advancement device (MAD) is an oral device that’s custom made for you to wear when you sleep. It holds the lower jaw in a forward position to widen the space behind the tongue. This reduces vibration and stops your airway from becoming obstructed.

Without Narval:
pharynx is collapsed and airflow is blocked

With Narval:
pharynx is open and air flows freely
What are the benefits of effective MAD therapy?
Snoring disappears
Loud snoring disappears in almost 90% of people who use Narval. Having a reliable way to avoid snoring could help you enjoy better sleep, have a positive impact on your relationship and help you feel more confident.
OSA symptoms are reduced
Narval also significantly reduces OSA symptoms: two thirds of OSA patients stop feeling tired during the day when they start using Narval.1
Quality of life improves
With effective MAD treatment for your sleep apnoea, you should also enjoy other benefits including better health, a healthier weight, a more positive mood, more daytime energy, happier relationships and a lower risk of accidents.
What to expect when you choose Narval CC
If you’ve chosen to use Narval CC to help you fight your snoring and reduce the severity of the apnoeas that leave you tired and listless – congratulations! You’re on the journey to better health. Here’s a short checklist of the key milestones along your journey:
Step 1
Make sure you’ve been screened for sleep apnoea, and that you know what your AHI is. Getting an optimal solution depends on having the right diagnosis. Plus, it’s the only way to monitor progress.
Find a dentist with experience in dental sleep therapy. You can ask your sleep physician for a referral, consult the European Dental Sleep Foundation registry, or contact us for help.
In general, you’ll need to see your dentist for a mouth examination and teeth imprints; then you’ll need fitting and adjustment.

Why should I choose a Narval appliance?

Narval is a clinically proven, non-invasive therapy for chronic, loud and bothersome snoring. It’s custom-made to fit precisely in your mouth using advanced CAD/CAM technology. It’s small, discreet and easy to use (including on holiday). You can talk, drink and open your mouth naturally when you wear it. It’s made of a composite material with zero metal, latex and bisphenol A to minimise the risk of allergies. And it’s extremely strong, so you can wear it even if you grind your teeth when you sleep.
