How does a Mandibular Advancement Device (also known as a Dental Sleep Device) or Oral Appliance Therapy work?

A Mandibular Advancement Device (MAD) works by a very precise, planned and temporary forward movement of the lower jaw, bringing the tongue forward, which causes a widening of the Airway, preventing it’s closure during Sleep. The cause of the Nighttime disturbance is an overcrowded airway (oropharynx) often causing Snoring, which may be a symptom of Obstructive Sleep Apnoea. Widening or opening of the Airway, reduces Snoring and Sleep Apnoea symptoms.

The Main features of Device Therapy are:

  • Device therapy holds the lower jaw (mandible) in a forward position, relative to the upper jaw (maxilla). This widens the Airway, facilitating overnight optimal Oxygenation, Optimal breathing, with reduced overnight noise.
  • The precise forward positioning of the lower jaw also moves the tongue forward. This prevents the tongue from falling backwards, especially when Sleeping in the supine position (with face upwards), obstructing the Airway.
  • The increased airway (oropharynx) reduces noisy vibrations, which can often cause snoring and also prevents incomplete or complete Airway closure, which leads to Sleep Apnoea.
  • The precise forward jaw position, facilitates the stabilization of the jaw and hyoid bone. This prevents the backward rotation, obstructing the airway while sleeping.
  • The specific alteration in the position of the lower jaw further affects the hard and soft tissue of the Oropharynx (Airway) increasing airway size (volume) and permeability, overnight.

The degree of Mandibular Advancement is important, as there is a dose-dependent effect on improving nighttime Oxygenation and reducing pharyngeal collapsibility. Mandibular Advancement Devices are the most effective in treating patients with Snoring and Mild to Moderate Obstructive Sleep Apnoea. Mandibular Advancement Device systems are also very helpful for patients who cannot manage nor tolerate C.P.A.P. (Continuous Positive Airways Pressure) who have a diagnosis of Severe Sleep Apnoea.
