Having a fully adjustable lower tray makes VitalSleep more effective than ZQuiet's design. With VitalSleep's Accu Adjust System, the lower tray can be adjusted 1 mm at a time up to 7 mm, by easily turning two screws. Increasing the forward position of the mouth guard's lower half will increase the opening of your airway and improve your breathing during sleep.
One of the benefits of having an Accu Adjust System is that VitalSleep users are able to slowly adjust the extent of advancement allowing them to transition slowly to the most effective distance of adjustment with minimized soreness that is common when beginning use of a MAD. VitalSleep is the most adjustable MAD on the market.
