Narval CC

Narval™ CC is ResMed’s premier oral appliance. As one of the lightest oral appliances available, Narval CC is designed to be discreet, comfortable and effective. Crafted from a lightweight, flexible and metal-free biocompatible material, unlike any other oral appliance, this specially designed device allows you the freedom and flexibility to talk and drink — a solution so comfortable, you’ll never want to go a night without it.

Narval CC works by simply holding your jaw in a forward position while you sleep to expand the space behind your tongue and help prevent obstruction and snoring. A recent clinical study found that worn nightly, Narval CC significantly reduces sleep apnea symptoms and improves quality of life.1 Get easygoing sleep therapy — night after night — with Narval CC.

Narval™ CC is the first and only CAD/CAM custom-made mandibular repositioning device (MRD) on the market. Narval CC is the ultimate MRD solution for patients with mild to moderate obstructive sleep apnea (OSA), as well as those who are unable to comply with continuous positive airway pressure (CPAP) treatment. It is also a first line treatment for snoring in the absence of OSA.

Ask your doctor or Dentist about Narval CC and check with your medical insurance provider to find out how oral appliances for sleep apnea are included in your plan.
