The Snoreeze Oral Device and the Snoreeze LabFit Oral Device are adjustable mouthpieces that treat loud snoring and sleep apnoea. They work by holding your jaw in the right position to keep your airway open. This allows you to breathe easily and quietly.
Oral devices are also known as mandibular advancement devices, snoring guards and snoring mouthpieces. Adjustable oral devices are approved by the National Institute for Health and Care Excellence (NICE) for the treatment of sleep apnoea.
Mandibular advancement works in two distinct ways: to reduce air turbulence caused by airway obstruction, and to inhibit collapse of the upper airway. By moving the jaw progressively forward, mandibular advancement pulls the tongue and other connected tissues forward. This creates more space between the base of the tongue and the epiglottis. Advancement of the jaw acts on the muscles of the velopharynx and the cross-sectional shape of the upper airway. In a majority of OSA patients, it increases the calibre (or tone) of the velopharynx musculature, making it less prone to collapse.
Clinical studies show that mandibular advancement:
- Tightens the soft tissues of the pharynx’s lateral walls. This reduces air turbulence and the soft tissue vibration that causes snoring.
- Activates the genioglossus muscle and increases airway muscle tone.
- Changes pharyngeal pressures to normalize the physiological properties of the upper airway.
