What is SomnoGuard® SPX?

SomnoGuard® SPX is a two-piece, adjustable mandibular advancement device (MAD). It is the latest development in the field of prefabricated SomnoGuard® 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 oral 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 oral appliance allows the width of the tray to be altered. After heating the trays in a hot water bath, they can be adapted according to the jaw size by gently pulling the trays apart or pressing them together.


Thanks to the memory effect, the thermoplastic material reverts almost to its original form when reheated. This allows the fitting of the trays to be easily repeated if the fit is not optimal.


The two-piece, adjustable mandibular advancement device mainly encloses the less sensitive rear teeth and the front teeth only from the front side. Thereby less pressure is exerted on the dentition. SomnoGuard® SPX allows mouth breathing and a slight mouth opening.

The fitting process only takes about 20 minutes

(Please also read the instructions for use)

1. Heat the trays in a hot water bath for approx. 60 seconds.

2. Bite into the soft thermoplastic material. It forms according to the teeth and leaves a dental impression.

3. Cool the trays in cold water to harden the material.

4. Connect the trays using two side connectors.

A special holder makes the adjustment of SomnoGuard® SPX even more comfortable. To do this, the tray is “clicked” into the holder, heated in the hot water bath and then fitted in the mouth.


How to adjust the protrusion of SomnoGuard® SPX?

The package includes two screw connectors as well as a connector set (connectors without screws). The extent of the mandibular advancement depends on the length of the connectors. The shorter the connectors, the greater the advancement. It is recommended to start the therapy with the screw connectors and – when the optimal protrusion has been determined – to use the connectors from the set (connectors without screws) for long-term use. However, therapy can also be started directly with the connectors without screws.


The screw connectors each have a spindle screw in their center. The length of the connectors can be changed by turning the spindle screws using the spanner. The screw connectors can be replaced in the long term with the connectors from the set (connectors without screws). To do this, measure the length of the screw connectors and then select the appropriate connector lengths from the set.


Depending on the extent of the adjusted mandibular advancement, the upper airway is more open. Snoring and nocturnal breathing pauses can thus be reduced.



Who is the SomnoGuard® SPX mandibular advancement device suitable for?

The SomnoGuard® SPX mandibular advancement device is suitable for every jaw size, also for patients with a receding lower jaw (retrognathia).
