ABSTRACT:
A combination bite block, tongue depressor/retractor and airway for establishing and maintaining an open airway while preventing emergence clenching and the resulting dental and soft tissue damage associated with emergence clenching in procedures where anesthesia and/or sedation are used, or when the patient is not in control of their own airway, regardless of the cause. The inventive subject matter includes a tongue depressor/retractor component in both right and left conformations; and a bite block component. The bite block component is a wedge shaped, compressible component that is inserted between the upper and lower molars on either the right or left side of the mouth. The tongue depressor component is comprised by a flat portion of that is inserted into the side of the bite block, and an optional curved portion that retracts the tongue off of the posterior pharynx when in place.
