A MAS is a simple, custom-made medical device similar to a mouthguard, but smaller and less bulky. The MAS is worn at night while you sleep and is designed to hold your lower jaw slightly forward to keep your airways open throughout the night.
This allows for easier breathing, reduces snoring sounds, and most importantly, can result in a marked improvement in sleep quantity and quality. Many patients report feeling more well rested and refreshed than they have in years (as do their partners).
MAS devices are easy to wear, and it is often possible to speak, yawn and drink while wearing them. They are small, light and easy to carry with you when you travel. The cost is similar to a CPAP and most health funds offer a rebate.
