Important Patient Information

AerStrap MAS
User Guide

The AerStrap MAS is a 3D laser-sintered appliance that has been custom-designed and made for your mouth. The device is both durable and strong.

The AerStrap MAS will position your lower jaw forward to make more room in your mouth for your tongue at night. This action and position for the tongue is supported by the Snore Attack Shield, which you should have received in the package sent to your dentist.

Is this device comfortable and easy to use?

Yes, it is not bulky in your mouth. Follow your dental professional's instructions on the daily use of the device.

I've been fitted with my AerStrap MAS. Do I need any follow-up appointments?​

Return to your dental professional yearly, or as often as necessary if sooner, for revaluation. DO NOT use this device if you have not seen a dentist in over 12 months.

Can I use other cleaning products that I prefer instead of the Aer Clean product?

We recommend Aer Clean because it has proven to be the best cleaner for nylon appliances.  Aer Healthcare has spent many hours researching and testing the best compound to safely and effectively clean the AerStrap MAS. Aer Healthcare has simple instructions to follow to keep your appliance clean. If you choose to use another cleaner, or you do not clean this device every day as recommended, Aer Healthcare can not support any warranty claim for unclean and damaged devices due to an improper cleaning process.

Will this device damage my teeth and bite?

Your dental professional will assess the apparent health of your teeth and you will be instructed on the correct use of this device. Any damage to teeth will not be due to the use of this product. The material can not damage the teeth; so as long as the teeth are sound nothing should happen. You may feel a sense of change in the way you bite in the morning. This will be a temporary change and should resolve on its own.

I have some missing teeth. Will this affect the AerStrap MAS?

Your dentist sohuld have determined that you have enough natural teeth, in a good and healthy state in the upper and lower arches. Implant fixtures in the upper and lower arches can be used to secure the device in the absence of a sufficient number of teeth.

I am about to have some dental work done. Will this affect the fit of my AerStrap MAS?

Seek advice from your dental professional. If the dental work is substantial, the top or bottom tray may need to be remade, and a fee for this will apply. This kind of non-fitting event is not covered by warranty.

My jaw feels sore. What should I do?

In the event of muscle or jaw pain, discontinue the use of the device immediately and contact your dental professional.

There is blood in my device when I take it out of my mouth in the morning, What should I do?

Blood in your AerStrap MAS may be an indication that your teeth and gums need a professional cleaning. Please talk to your dentist about strategies on how to keep your teeth and gums healthy. Do not allow the blood to dry on the device, rinse it well and soak the device in Aer Clean solution as directed.

My AerStrap MAS is damaged. What should I do?

Discontinue use immediately and consult your dental professional

When I use the Snore Attack Shield, I can not breathe out of my mouth. What should I do?

You may experience obstruction of oral breathing with any oral appliance in the mouth. The Snore Attack Shield, combined with the AerStrap MAS, ''retrains'' your breathing so that you breathe exclusively through your nose. Ensure that you can breathe through your nose BEFORE using this device.

My nose feels ''too small'' when I use the Snore Attack Shield and I feel like I can not breathe well even though my nose is clear. What should I do?

Sometimes your nose can collapse at the front when you breathe through at night. Nasal cones or strips can help with this issue. Click here if you want to buy nasal cones.
