When is a Mandibular Advancement Splint worn?

The Mandibular Advancement Splint (MAS) is worn anytime you sleep. The device is very discrete, allowing you to close your lips so it is not obvious that you are wearing it.

Is it comfortable?

It is custom made to fit your mouth and it does not impinge on your tongue. You can open and close your mouth normally as the MAS does not lock or fix your jaws together.

What will the dentist do?
On your first visit, we will thoroughly examine your teeth and mouth and may use X-rays to confirm your oral health status, as well as ensuring that you are dentally appropriate for the device. Dental impressions are required to fabricate a MAS. They are taken, and sent to our laboratory where the appliance is made. Once custom made for you, the appliance will be inserted and you will be shown how to insert and remove it yourself, as well as how to clean and care for it.

What is an oral appliance?

An oral appliance is a small device, similar to an orthodontic retainer or an athletic mouthguard. It is worn in the mouth during sleep to prevent the soft throat tissues from collapsing and obstructing the airway. Some appliances hold the lower jaw forward during sleep while others have direct effect on tongue position. Oral appliances relieve snoring and may treat OSA by realigning the jaw and/or tongue in relation to the head. Although oral appliances do not work on everybody, a well-made, well-fitted appliance may reduce or eliminate snoring, and may significantly relieve symptoms of OSA.  

Are oral appliances effective?

Oral appliances were first utilized in the 1930's to help people breathe properly during sleep. By the 1980's, physicians and dentists began to seriously study the effectiveness of oral appliances to treat snoring and obstructive sleep apnea and found them to be effective in many, but not all cases. Recent studies show oral appliances to be effective in treating snoring and mild to moderate obstructive sleep apnea.    

Are all Oral Devices as good as each other?

No. There is a range of such devices available, some of which are not custom-made or adjustable. Most are either uncomfortable, ineffective or both.  We carefully choose the appliance that will work best for you. 

What is a MAS?

The MAS is a custom made medical device, designed to hold your lower jaw (mandible) forward while you sleep. This tightens the muscles of the upper airway to allow easier breathing. The  MAS is a type of oral appliance, comprised of upper and lower components, which allows normal mouth opening and closing. The device titrates easily to achieve comfortable usage. 

What if I have a bridge or denture?  
Patients with crowns or bridges can be successfully fitted with a MAS appliance. Adjustments are made in the appliance to ensure that fragile crowns and bridges are not harmed.

Sufficient healthy teeth are required in order to use an oral appliance. In order to be fitted for the appliance, a patient must have at least a few lower natural teeth and it is acceptable to have an upper denture. Patients with partial dentures may be successfully fitted with a MAS as long as there are sufficient teeth on the lower arch for optimal retention.

The MAS may be fitted over dental implants.  An edentulous upper splint covers the palate in the same way as a full upper denture secured by suction and made to oppose a lower splint.
