To the Editor.—In the February Archives, Salisbury et al1 described an appliance to protect the maxillary teeth and palate during endoscopy using a heat-cured acrylic splint fabricated in a dental laboratory. We have found that silicone dental impression material makes a thoroughly satisfactory appliance for this purpose. Polysiloxanes, which have the greatest final hardness, are the most suitable formulations. The appliance can be made by the surgeon in five to ten minutes either at the bedside or in the operating room, and thus there is no delay for fabrication. The material is durable (it is used for dental guards in athletics), yet disposable, with a unit cost of 10 to 15 cents.
