Obstructive Sleep Apnoea

Snoring, Grinding and Obstructive Sleep Apnoea (OSA or MAD) appliances

What is Obstructive Sleep Apnoea?

Obstructive Sleep Apnoea (OSA) is a severe and chronic medical condition that affects 750,000 Australians. As we get older, its incidence increases affecting your sleep, health and quality of life. OSA has been linked to hypertension, diabetes, heart disease, stroke and driving related accidents and it can also put unnecessary strain on your relationships

What Causes OSA?

During sleep, the muscles that control the tongue and throat relax. The airway becomes narrowed and constricted when the tissue at the back of the throat sags and incoming air then makes the tissue at the rear roof of the mouth (the soft palate), the flap of skin hanging from the palate (uvula) and the throat vibrate, making the unpleasant sound that we call snoring.

It is essential to seek treatment if you or a loved one have OSA or show symptoms like snoring, excessive sleepiness during the day, pauses in breathing or teeth grinding while you sleep.

Ask yourself these questions:

  • Do you snore?
  • Do you have high blood pressure?
  • Do you feel unusually tired during the day?
  • Have you been told you choke or gasp while you sleep?
  • Have you tried any treatments for sleep disordered breathing?

If you answered “yes” to ANY of these questions, ask us about being evaluated further for risk of sleep disordered breathing and treatment options.


In MouthOne of the treatment options we can prescribe is a custom made Mandibular Advancement Device (MAD) or Splint for you, such as SomnoDent. A SomnoDent device gently and non-invasively adjusts the forward movement of your jaw, which then opens your airway to help breathe easily and have a restful sleep. The SomnoDent appliance is custom made to fit your teeth and mouth and fits over your upper and lower teeth, similar to a sports mouth guard.

We will…

  • Review your sleep condition history
  • Perform a complete examination of your teeth, mouth, head and neck
  • Make a model or cast of your teeth and mouth to send to the lab to custom make your device
  • Take a bite impression to establish how far forward to move your jaw in a comfortable position
  • Once the device comes back form the lab, we’ll make sure it fits correctly and will adjust it for optimal treatment results
