Abstract
An apparatus for maintaining a dry field during dental procedures includes a U-shaped tongue shield for holding the patient's tongue in a retracted position. Cheek distention arms extend laterally outward and forward from the tongue shield to distend the cheek away from the teeth. Lip retractors extend from the cheek distention arms in an arcuate shape above and below the cheek distention arms. Webbing extends between the lip retractors and cheek distention arms to support the soft tissue within the patient's mouth distal to the orbicularis oris muscle.
