A dental device (10) includes a tongue-retracting surface (14) and a throat dam (15, 16) adapted to be positioned in the mouth of a patient. Integral lip-retracting surfaces (17) and a grip portion (18) are connected to the tongue-retracting surface (14) and throat dam (15, 16) by a prop portion (12) which preferably have angled biting surfaces (19) adapted to be engaged by the teeth of the patient. An expandable throat barrier net (23) may be attached to a portion of the throat dam (15). An evacuation system (30) may be provided to remove fluids from the mouth. The biting surfaces (19) may be provided with a pad (21) or a thermoplastic material (22) for the comfort of the patient. A reflective material (27) may be attached to the tongue-retracting surface (14) and a fiber optic rod (28) may be carried by the tongue-retracting surface (14) to assist in illuminating the oral cavity of the patient.
A dental device adapted to be placed in the mouth of a patient comprising an intra-oral portion including a tongue retractor and a throat dam, said throat dam being in the form of a u-shaped flange that extends away from the cheek of the patient when the dental device is placed in the patient's mouth, an extra-oral portion including lip-retracting surfaces and a grip portion, and a prop portion integrally connecting said intra-oral portion and said extra-oral portion, said prop portion having opposed biting surfaces adapted to be engaged by the teeth of the patient.
