Oral Anti-Snoring Device

Snoring is the vibration of the respiratory structures that result in a sound due to obstructed air movement during breathing while sleeping.

Snoring Signs and Symptoms

  • Restless sleep
  • Awakenings due to gasping or choking
  • Personality changes
  • Morning headaches
  • Family, Social and Work problems

Normal Airflow
  • Snoring is a partial airway obstruction that reduces the airflow but does not cause arousal from sleep
  • Apnea is a more than 80% decrease in the airflow for at least 10 seconds, ending with an arousal from sleep

Mechanism of Action of Oral Appliances:

Tongue retaining devices

  • Advances the base of the tongue
  • Actively holds tongue forward to open airway

Mandibular advancement devices

  • Repositions and stabilizes the mandible, tongue, and hyoid bone (and sometimes the soft palate)
  • Increases baseline genioglossus muscle activity
