If your diagnostic sleep study reveals that you have mild to moderate obstructive sleep apnoea, your sleep physician may recommend that you use a mandibular advancement splint. A mandibular advancement splint (pictured to the right) should be fitted by a specialist dentist. This device works to treat your obstructive sleep apnoea by moving your jaw forward thus opening your airway so that you no longer have pauses in breathing overnight.
After being fitted with a mandibular advancement splint (MAS) your sleep physician may request a second sleep study to ensure that your sleep apnoea is being controlled by the device and doesn't need any adjustments. This type of sleep study is the same as a diagnostic sleep study, however you will also be using your MAS device during your sleep.
