SomnoGuard® SPX is a two-piece mandibular advancement device that allows limited mouth opening. It is our latest development in the field of prefabricated SomnoGuard® mandibular advancement devices and represents a new generation of mandibular advancement devices. The two oral trays consist of a hard outer tray shell and a prefabricated thermoplastic material with memory effect. After heating the trays in a hot water bath, the thermoplastic material becomes easily mouldable. Teeth impressions are formed when biting into the soft material (comparable with a dental impression). After the appliance cools down in a cold water bath, the material hardens and maintains its new shape.
A special slot mechanism in the centre of the front part of the appliance allows the width of the tray to be altered. After heating the trays in a hot water bath, they can be altered according to the jaw size by gently pulling the trays apart or pressing them together.
SomnoGuard® SPX causes the desired advancement of the lower jaw and tongue, and thus the opening of the airways. Snoring is reduced or at best even prevented.

Two connectors of equal length connect the upper with the lower jaw. The lower jaw advancement can be infinitely adjusted by turning the screws between the connectors with the spanner. The opening of the respiratory tract depends on the extent of the adjusted lower jaw advancement.
