Narval CC: key features

What is sleep apnea?

Narval CC™ is a clinically-proven1 oral appliance that's custom-made for greater comfort and compliance for your patients. It’s one of the smallest and lightest oral appliances available on the market.

In a five-year ResMed ongoing clinical study, we found that:

  • Patients used it on average 6.7 hours per night, and 6.7 nights per week.
  • Narval CC successfully stops loud snoring in almost 80% of patients who use it.

  • Almost 80% of people who used Narval CC to fight their sleep apnoea — including those with more severe cases of OSA — saw their Apnoea-Hypopnea Index (AHI) decrease by more than 50%.1

  • A bespoke solution that maximises precision and comfort: ResMed is today one of the few companies to use computer-aided design and manufacturing (CAD/CAM) for its oral appliance. Studies show that patients prefer custom-made mandibular repositioning devices (MRDs) over thermo-plastic ones they buy off-the-shelf.2
  • Strong, lightweight material for greater precision: Narval CC is made of polymer, a lightweight and strong material that doesn't smell or leak. It is designed to withstand teeth grinding from patients with bruxism.3
  • Biocompatible4: Polymer is not made from acrylic, metals, latex, paraben or bisphenol A. It’s hygienic to minimise the risk of allergies.
  • Innovative retention method: Narval CC clips onto teeth rather than wrap around them, Narval CC doesn't slide around in their mouth, or stick to their teeth as they take it off.
  • Less stress on teeth and jaw muscles: Narval CC is designed to reduce stress on your patients’ teeth and jaw muscles.5 And it’s designed to make it easy for a dentist to find just the right balance between comfort and treatment effectiveness.
  • Patented articulation: Narval CC’s articulation enables your patients to sleep with their mouth closed5 – but gives them the flexibility to open it, and even drink if necessary. 
  • Manufactured in France and the US: Devices for the European market are manufactured in Lyon, France, whilst those in the USA and Canada are made near San Diego in California.
