ABSTRACT:
A combined mouth retracting and saliva ejecting device has a forward suction portion, a right cheek retractor portion, a left cheek retractor portion, and a rearward suction portion, the device being configured to be placed within the mouth of a dental patient. The device is constructed of a single piece of rigid, but resilient, tubular material, the material having an elastomeric memory. The device is tubular and has a cylindrical or other shape cross section and can be constructed of material so as to be either disposable or nondisposable, the nondisposable version being capable of heat or chemical sterilization. The device can be made in almost any size to accommodate the wide variety of patients that it may be used with, including children. The device may also incorporate fiber optic technology whereby light transmissive fibers are imbedded into the device to allow for selective illumination within the patient's mouth as either a light source for light curable dental compounds or for enhanced visualization.
