Role of the Dentist in the management of Snoring and

Mild to Moderate Sleep Apnea.

Management of snoring and "sleep disturbances" using dental appliances is a growth industry. Appliances are simple to make, are universally effective and non-invasive.

Dentists see more patients more frequently than do most health care practitioners and look in the mouth and down the throat of every patient they see.

It is easy for a dentist to observe tell tale signs of snoring/sleep apnea. Size of the tongue, soft palate, u vulva, tonsils, tonsilar pillars, anatomical obstructions. Also look for signs of chronic snoring; presence of pharyngeal edema or abnormal redness.

An astute observer may also notice behavior indicative of sleepiness or fatigue; lethargy, yawning, sighing, slouching, drooping eyelids.

Asking the patient very specific questions can also help to confirm snoring/sleep apnea.

  • Have you ever been told you snore.
  • Do you fall asleep at meetings, watching TV, or reading.
  • Do you feel tired when you wake in the morning or have headaches.
  • Do you feel tired and listless during the day.

Depending on your assessment of the answers you may decide to send the patient to see a Respiratory/Sleep Specialist.

With Dental Oral Appliances being increasingly accepted as an alternative to conventional therapies and CPAP. The role of the Dentist as part of an overall multidicinplinary team is also increasing.

What's needed from the Dentist for the Dental Lab to custom make a comfortable patient compliant MDSA® Adjustable Appliance.

Patient Impressions and Bite Registration.

A protrusive registration, centre aligned with 5mm opening and notation of the approximate amount of advancement where the registration was taken (eq 40% of full passive protrusion). This will ensure the Lab can align the impressions and overcome occlusions when the jaw is advanced.


Any commonly available registration will do

When fitting the patient the Dentist checks for patient comfort, trimming any problem areas and initially setting the advancement at 60-70% of full advancement.

The patient should be advised they could experience transient discomforts for the first couple of weeks, increased salivation etc. If they feel they are uncomfortable with the fitting they should not hesitate to contact the Dentist.

The patient should return at the end of 2 weeks for follow up check and positioning of the advancement etc.

Patient should then come back after 3 months and then on a regular 6 months for check up on alleviation of symptoms and condition of patient teeth etc. It is common that after 3-6months with relaxation of TMJ's the appliance may need to be advanced slightly further.

In a small percentage of patients occlusions have been reported as with change in bite and over jet.

Patients should be made aware of these possibilities at the time of first consultation and consent forms signed.

It is the patients responsibility to continually clean and inspect the appliance and if there is any cracking or degradation return for repairs.

The MDSA is supplied with patient instructions which they should be aware of and follow.
