ABSTRACT:
A dental guard fittable over a patient's upper incisors is composed of an arcuate plastic tray of about 1.5 inches in length and having in cross-section a U-shape. A compliant elastomeric adhesive plug of a hydrogel lies within and is self-adhered to the channel of the U-shaped tray so that when pressed into place over the patient's incisors, the teeth remain embedded in the plug and the dental guard remains adhered in position over the incisors but leaves the posterior teeth (molars including premolars) on either side uncovered. The use of such a dental guard protects the incisors from the levering forces exerted by the laryngoscope blade during intubation and provides the intubator an unobstructed view for easily guiding an endotracheal tube via the pharynx through the vocal cords and into the trachea.
