Custom-Fitted Oral Immobilization

      and Tongue Displacement Stent

​

 

 

 

The GrayDuckTM Stent is a new tongue-displacing device, providing oral mucosal sparing and jaw immobilization during head and neck radiotherapy. Requiring less than 10 minutes to custom-fit a patient, the patented GrayDuckTM Stent immobilizes the jaw in the same position for each radiotherapy treatment.  GrayDuckTM deviates the tongue in a number of directions; laterally (left or right) or depressing (downward).

Instructions for Use

GrayDuckTM is custom-formed to each patient by undertaking these simple procedures:

​

       1.    The stent is placed in hot water for two minutes before placing in the patient’s mouth to custom form teeth to the softer teeth-                         contact material  

       2.    The stent paddle type is selected for tongue deviation.  It is inserted into the stent body and snapped into the universal                                 joint/gimbal. Adjustments are made as necessary to ensure proper paddle placement and patient tolerance
