GrayDuckTM Stent

        Introducing a new custom oral stent to                        provide immobilization and tissue sparing                  during head and neck radiotherapy

Introducing the only custom-fitted bite block      that can deviate the tongue in multiple directions  




The GrayDuck Stent is a new tongue-displacing oral stent, providing mucosal sparing and immobilization of the tongue, teeth and jaw during head and neck radiotherapy.  


The patented GrayDuck Stent immobilizes the jaw in the same position each time during treatment and deviates the tongue in a number of positions; laterally (left or right) or depressing (downward).  


GrayDuck  is custom-fitted to each patient and requires about 10 minutes for initial fitting.
