Sleep Apnea

How the SomnoMed MASTM Works

How is Sleep Apnea Diagnosed and what Causes Snoring and Sleep Apnea?

If you or your loved one thinks you may suffer from Sleep Apnea you must have a sleep study completed in order to be diagnosed with the condition. Oral appliances are only indicated for use in patients suffering from obstructive sleep apnea (OSA). The signs and symptoms of OSA include snoring, excessive daytime sleepiness, gasping or choking during the night, non-refreshed sleep, fragmented sleep, clouded memory, irritability, personality changes, decreased sex drive, impotence, and morning headaches.

Factors that affect obstructive sleep apnea are as follows:

  • Age
  • Obesity
  • Alcohol
  • Sedative Hypnotics (sleeping pills)


When the airway narrows or partially collapses snoring results, which is the sound of tissues vibrating. Where there is complete collapse, you have an incidence of sleep apnea, which is when breathing stops altogether.

Is the SomnoMed MAS™ for you?

SomnoMed MAS™ is an effective treatment both mild to moderate obstructive sleep apnea.

OSA is characterized by repeated cycles of partial or complete collapse of the upper airway during sleep. This results in a cessation or reduction of breathing and a decrease in blood oxygen levels resulting in typically unremembered awakenings.

The severity of OSA is defined by the number of these occurrences per hour of sleep. These episodes of obstruction, along with the resultant awakening of the OSA sufferer, occur five or more times per hour, potentially causing marked sleep disruption.

OSA is generally defined as being in the Mild to Moderate level where the SomnoMed MAS™ could be an effective treatment for you.

What the SomnoMed MASTM does

The SomnoMed MAS™ positions your lower jaw slightly forward of its natural position, which has the effect of tightening the soft flesh (or tissue) at the back of your throat, which prevents it from collapsing. The patented fin-coupling mechanism on the lower arch of the SomnoMed splint ensures that your lower jaw (mandible) remains in the correct position, whether you sleep with your mouth open or closed  or open your mouth for any other reason, such as to take a drink. This freedom to move your jaw up and down, without compromising the effectiveness of the device, is a unique feature of the SomnoMed MAS™.

Clinical Trials of SomnoMed MASTM

The SomnoMed MAS™ has been tested in clinical trials, with the results published in prestigious medical journals. It is the only oral appliance with such a body of clinical research to substantiate its effectiveness.

Key Points

  • The SomnoMed MAS™ is clinically validated for the treatment of snoring and OSA.
  • The SomnoMed MAS™ has helped people who have tried other OSA treatments and been unsuccessful or have not complied with their CPAP treatment.
  • The American Academy of Sleep Medicine recommends oral appliances as a first line treatment for snoring and mild to moderate OSA.


Research and clinical trials Research and clinical trials using earlier models of the current model of SomnoMed MAS™ conducted by the Department of Respiratory and Sleep Medicine at St George Hospital, Sydney have found a high level of acceptance and tolerance amongst patients's and concluded that the SomnoMed MAS™ is a viable alternative to CPAP in the treatment of OSA.
