Sleep-disordered breathing and sleep apnoea are important health issues. “Snoring” can not only impact your bed partner, but can also be associated with a more serious condition called sleep apnoea. “Snoring” is an attempt to open the airways. This is the first sign of sleep disordered breathing. When a person stops breathing for more than 10 seconds during their sleep cycles then the condition is classified as apnoea. The airway obstruction can be partial or complete. All people who snore should be evaluated for obstructive sleep apnoea.

If you suffer from any of the following symptoms you may have sleep-disordered breathing or sleep apnoea:

  • Tiredness and dried throat upon waking
  • Excessive daytime sleepiness and lack of focus during the day
  • High blood pressure or heart disease
  • Anxiety or depression
  • Grinding or clenching
  • Morning headaches
  • Sexual problems
  • Intermittent snoring
  • Gasping and choking during sleep
  • Poor memory which can decrease job performance
  • Irritability and personality changes
  • GERD (Gastroesophageal reflux disease) a digestive disease in which stomach acid or bile irritates the food pipe lining.

Sleep-disordered breathing (SDB) is the result of a problem with either the oral airway or the nasal passages. Sleep-disordered breathing (SDB) and the related clinical syndrome, sleep apnoea, have been associated with hypertension in clinical reports since the early 1980s. Nasal obstruction frequently has been associated with sleep-disordered breathing as a potential etiologic factor

Oral airway abnormality can be related to:

  • Large tonsils and adenoids
  • Small airway
  • Crooked teeth
  • Hormonal imbalance (menopause)
  • Obesity
  • Pregnancy
  • Nasal passage obstructions include:
  • Sinus problems
  • Allergies
  • Large inferior turbinates
  • Collapsing of the airway during breathing in and out

We suggest patients to do overnight sleep studies to diagnose sleep disorders such as sleep apnoea. The sleep study will determine the level of severity of sleep apnoea.

Other sleep disorders can be diagnosed through sleep study such as restless leg syndrome and insomnia.

The sleep study can be done in the hospital or in the home. The home sleep study gives patients the comfort of sleeping in a natural environment. However, in some complex cases we suggest the patient to do an overnight sleep test in a hospital.

After analysing the data by a sleep physician, based on the degree of sleep apnea we suggest the sleep appliance or CPAP machine.


Oral appliances are custom designed for individual patients based on a complete assessment and an accurate bite registration. Some patients may choose to use over the counter appliances, which we do not recommend as they are often inaccurate and may lead to further health complications.
We offer the following appliances based on the patient’s specific problem:

  • ON6
  • Dorsal
  • EMA
