ABSTRACT:
A dental chair overlay is used for opening a patient's airway. The dental chair overlay has a body support and a head support. The body support has a superior end and dorsal and ventral surfaces. The distance between the dorsal and ventral surfaces define a thickness of the body support. The head support is attached to the superior end of the body support. The head support has dorsal and ventral surfaces. The distance between the dorsal and ventral surfaces define a thickness of the head support. The thickness of the body support is greater than the thickness of the head support, such that the airway of a patient lying on the dental chair overlay is urged open.
