Directions for use: The one-piece mandibular advancement device (MAD) / anti-snoring mouthpiece is infinitely adjustable can be customised in a warm water bath. Remouldable several times. The upper jaw and lower jaw mouthpieces are connected with each other by means of a fine adjustment screw. The MAD can move the jaw forward by between 0 - 10 mm, thereby opening the upper airways (obstructed airways are a major cause of snoring). Snoring is thus prevented. Comfortable thanks to the individual adjustment of the anti-snoring mouthpiece by means of fine adjustment screws and high-quality materials.
