AASM Practice Parameters

Oral appliances are indicated for use in
the following patients:

1st Line Treatment

  • Mild to moderate OSA (AHI 5–30) for patients who:
    • – Prefer MRDs over CPAP
    • – Do not respond to CPAP
    • – Are inappropriate candidates for or fail CPAP
    • – Fail behavioral measures treatment
  • Primary snoring for patients who do not respond or are not appropriate candidates for behavioral measures treatment

2nd Line Treatment

  • Severe OSAS (AHI>30) in case of lack of compliance with CPAP


Technical benefits
  • Computer-aided design (CAD) enables a high degree of customization
    to suit the complex dental anatomy of individual patients
  • Computer-aided manufacturing (CAM) through selective laser
    sintering guarantees a consistently accurate MRD
  • Made of highly resilient and durable biocompatible polymer
    material; Narval is metal-free, flexible and lightweight
  • Narval CC focuses retention on select teeth, relying on
    material friction and unique design to secure the device
    in place and maintain efficacy

Clinical benefits

High compliance

  • 80% of patients wear the Narval device seven nights a week by six weeks into the treatment
  • Treatment compliance was high after 18 months with the Narval CC being worn an average of 6.2 nights per week3
  • Easy to titrate, highly adjustable (15 mm protrusive range–1 mm increments)

Demonstrated results

  • Patients with moderate OSA exhibited an average decrease in apnea–hypopnea index (AHI) of 57%
  • Rapid improvement on parameters of sleepiness and quality of life
Patient benefits

Discrete and comfortable—yet effective

  • Minimal bulk in the mouth ensures patient comfort and compliance
  • Lateral flexibility eliminates “locked-in” sensation and offers freedom to talk and drink
  • Narval device does not load incisors, thereby limiting risk of incisor tilting and improving patient comfort
