Sleep apnoea and snoring appliances
For people diagnosed with obstructive sleep apnoea, a custom oral appliance can be an alternative to CPAP, particularly in mild to moderate cases or where CPAP has not been tolerated. Dr Justin Lee is a SomnoMed provider at Westfield Belconnen.
Sleep apnoea is diagnosed by a doctor, not a dentist. Obstructive sleep apnoea is diagnosed by a medical practitioner, usually a sleep physician, following a sleep study. A dental appliance is one treatment option after that diagnosis. If you suspect you have sleep apnoea and have not been assessed, please start with your GP.
How an oral appliance works
In obstructive sleep apnoea, the airway narrows or closes during sleep. A mandibular advancement appliance holds the lower jaw slightly forward overnight, which helps hold that airway open.
It is worn like a mouthguard, custom made to your teeth, and is considerably more portable than a CPAP machine. For people who travel, or who have given up on a mask, that practicality is often what makes the difference between a treatment that gets used and one that sits in a cupboard.
SomnoDent Avant. The SomnoMed device I most often fit. Custom made, less bulky than older designs, and it allows some jaw movement while worn.
What the process involves
- 01
Diagnosis comes first
A sleep physician diagnoses obstructive sleep apnoea from a sleep study. If you have not had one, start with your GP for a referral. Nothing here replaces that step.
- 02
Assessment of your teeth and jaw
Not everyone is suitable. You need enough healthy teeth to anchor the appliance, and your jaw joint needs to tolerate the position. That is what I check.
- 03
Scans and fitting
Digital scans or impressions go to the laboratory, and the appliance is made to your mouth. Fitting takes one appointment, with the position set conservatively to begin with.
- 04
Adjustment and review
The jaw position is advanced gradually over following visits, based on how you are sleeping and how your jaw feels. Your sleep physician may want a follow-up study to confirm it is working.
Grinding your teeth is a different problem
Bruxism and sleep apnoea sometimes occur together, but they are separate conditions treated with different devices. If your concern is worn teeth, a sore jaw or a partner hearing grinding rather than gasping, a night guard is what you are after.
