Snoring & Sleep Apnoea
Are you consistently feeling exhausted? Or is your partner a persistent snorer?
Around 40% of the population are snorers. Some snore regularly and some only after a few drinks, a heavy meal or if very tired and some others only while lying on the back. Snoring can not only affect intimate relationships and embarrass people who travel or visit friends but also indicate a potentially far more sinister and potentially life-threatening problem called Obstructive Sleep Apnoea or OSA.
What is OSA and how do you know you have it?
Obstructive sleep apnoea is a breathing disorder that happens for some while they sleep. Often linked with snoring and other symptoms, sleep apnoea is caused by the airways collapsing throughout the night. The tongue falls back across the pharynx (the rear part of the mouth down to the voice box and throat area) during sleep when the muscles of the throat and tongue relax causing a partial or total blockage of the airway and breathing. This causes temporary pauses of breathing and results in less oxygen reaching the brain (and rest of the body).
here are, in fact, a number of areas where collapse of the airway can occur. Not only can the tongue drop back onto the back of the throat but also onto the soft palate and uvula, thus blocking the airway.
The soft palate may become elongated and drape deeply behind the tongue and/or lose its muscular tone thus lying back against the back of the oro-pharynx just as the tongue does.
The side-walls of the pharynx may collapse in toward the centre of the airway causing temporary blockage on breathing out.
In the hypo pharynx, the epiglottis may collapse over the throat.
These pauses can range from 10 seconds to over a minute and may occur hundreds of times in one single evening. Because of the lack of oxygen to the brain, it forces you to wake and breathe (although you may not realise you’ve woken up). Because you have had an inconsistent rest and interrupted sleeping patterns, during the hours of the day you’ll likely feel sleepy and even agitated.
Left untreated, obstructive sleep apnoea can also lead to a range of other harmful conditions such as:
- Increased risk of heart attack and stroke
- Dementia and Alzheimer’s disease
- OSA is a very common cause of single vehicle fatal accidents when the driver falls asleep behind the wheel. It also results in an increase in industrial and work-related accidents and poor decision making and inaccurate work. It is frequently accompanied by an increase in resting blood pressure with all those associated health risks as well.
- Clinical depression
There is a very high association between OSA and gastric reflux (GORD or GERD) and bruxism (grinding and clenching teeth) and clinical depression.
- 96% of people who have GORD and Bruxism also have OSA
- 70% of people with depression also have OSA
- 28% of the population over 50 have OSA
- It is more prevalent in males
- Obesity, morbid obesity and metabolic syndrome are high risk factors for OSA
- Poly-cystic ovary syndrome (PCOS) is often associated with OSA
OSA and diabetes, are the two sleeping giants of medicine and, increasingly, your dentist or hygienist is the first to pick up on it.
How can your dentist help you?
Future Dental has been working with patients suffering from OSA for decades. Since 1980, we have constructed a wide range of appliances to help our patients. Because of our experience in this field, we have determined that one particular type stands out from the rest as a comfortable reliable appliance – the Mandibular Advancement Splints (MAS).
While a CPAPmachine is still regarded as the gold standard of treatment for OSA, up to 60% of users are not compliant with this treatment due to social, psychological, comfort and convenience factors. With increasing frequency, MAS are being recognised as an excellent substitute treatment.
While MAS’s still mean having to wear an appliance in the mouth, it is far less inconvenient than CPAP. Recent studies also indicate that a well-made MAS of the right type fitted by a practitioner is just as efficient in treating OSA as CPAP.
After Future Dental has assessed your risk factors and determined the best MAS appliance for you, the Australian companies of OVENTUS or Somnomed fabricates these from impressions and protrusive bite registrations of your jaws taken in a 30-minute visit. We get them back in about 2 to 4 weeks, at which point you will require a further 30-minute appointment to fit them and run through maintenance and adjustments.
While Dr Gibbins has made a number of different brands or types of Snoring appliances over the last 40 years or so, now he concentrates on only 2 brands but predominantly 1.
While Somnomed appliances are a good for snoring and mild sleep apnoea, the same results are achievable by any of the various Oventus appliances which include
Oventus Mono, Oventus 2 Vent T (titratable), Oventus O2 Vent W (winged), Oventus TRD ( tongue retaining device) and now with the latest and probably best addition, The Oventus Optima Device. The Oventus range of appliances are unique in the world of sleep appliances in that each type incorporates an in-built airway that by-passes large tongues, low draping flaccid soft palates and, even better, works equally well if the nose is partly or fully obstructed.
This additional benefit from all Oventus appliances gives them a significantly higher effectiveness in being able to treat even moderate and severe obstructive sleep apnoea.
The ability of Oventus appliances to work equally well in people with nasal obstruction is a unique advantage of Oventus Appliances as all other types and brands of sleep appliances and also CPAP have far less efficacy in anyone who is a mouth breather because of nasal obstruction.

Epworth Sleepiness Scale
Epworth Sleepiness Scale
How likely are you to doze off or fall asleep during the day in the following situations, in contrast to feeling just tired? Even if you have not done these things recently, try to work out how they would have affected you.
Use the following scale to choose the most appropriate number for each situation.
- 0 = would never doze
- 1 = Slight chance of dozing
- 2 = moderate chance of dozing
- 3 = high chance of dozing
- Sitting reading __
- Watching T.V. __
- Sitting inactive in public (e.g. Theatre, meeting) __
- As a passenger in a car for an hour without a break __
- Lying down to rest in the afternoon when able __
- Sitting and talking to someone __
- Sitting quietly after lunch without alcohol __
- In a car, while stopped for a few minutes in traffic __
<8 Indicated normal sleep function
8-10 Indicates mild sleepiness
11-15 Indicates moderate sleepiness
16-20 Indicates severe sleepiness
21-24 Indicates excessive sleepiness
As most people may have trouble answering many of these questions, we find that asking the bed partner the questions often helps to get the most accurate answer to the above.
PLEASE ANSWER THE FOLLOWING QUESTION AS FOLLOWS:
- Does your partner snore loudly?
- Does your partner snore in all positions?
- How often are you kept awake by snoring?
- How often are you forced to sleep in another room?
- For never
- For rarely
- For sometimes
- For often
- For always
Snoring no longer needs to affect your relationships and you can look forward to a far healthier life if your OSA is treated correctly.
