Profile: OrthoQuest offers quest™ dry field system, which avoids moisture contamination during intra-oral procedures. Our exclusive patented design combines a tongue shield, mouth prop, and suction system that provides a dry isolated field for dental procedures. The tongue shield is designed so that it also functions as a mouth prop. When placed in the mouth, the upper portion engages the patient's palate. This comfortably and effectively props the mouth open, while preventing the tongue from coming in contact with any tooth surface. The design also enhances visibility for easier access to 2nd molars.
