Abstract

An essentially a U-shaped oral isolation device having a tongue arm, a buccal arm, and a hinge section is provided. The device is an essentially hollow member having an upper suction chamber and a lower suction chamber within the hollows of the oral isolation device. Each chamber further comprising suction inlet apertures through which saliva, fluid, aerosol mist, and debris can be evacuated from the operative site, and a suction outlet chamber through which the collected saliva, fluid, and debris are removed from the device. A U-shaped hinge member joins the buccal arm and the tongue arm. It has position memory which permits the user to squeeze the arm members toward one another for placement in the mouth and upon release, the arm members exert opposing positional influence against the tongue and cheek. Also provided is a method of use for the device in which the tongue arm and buccal arms are forced toward one another. The hinged member is then inserted into the patient's oral cavity and placed around the rearmost tooth. Upon proper placement of the device, the user releases the pressure on the arms of the device, the arms thereby exerting opposing positional influence against the cheek and tongue, resulting in retraction of the tongue and cheek, thereby creating a clear operative field. A reduced pressure high volume device is then attached to the upper chamber suction outlet and a low pressure reduced volume device is attached to the lower chamber outlet.
