In using this appliance the tongue is placed into the anterior bulb. Pushing the tongue forward and giving the bulb a little squeeze creates a suction that holds the tongue in the forward position. All the other appliances work by bringing the mandible forward. But everyone can not have their mandible brought forward due to other dental problems. In those cases the tongue appliance works well and has excellent sleep studies to support its use. The only drawback is that it is not very comfortable.
Ideal For These Types Of Patients:
The TSD positions the tongue forward from obstructing the airway, instead of moving the mandible. It also uses gentle suction, rather than the dentition to stay in place.
