This video shows how an EMA device is advanced. Yours may look different than this one as there are many different types. On this design the lower the number on the strap the more the airway is opened. In treatment we start in a very neutral position on purpose to allow time to get used to wearing the device. After this initial transition the device is often advanced to open the airway further and improve sleep and breathing. By advancing the device we are advancing the mandible and opening the airway further. This is how sleep and breathing are improved and snoring is reduced.
