ABSTRACT:
A dental appliance is made up of an elongated body having a substantially longitudinal axis with opposite end portions making up substantially flat surfaces extending laterally the axis for being engaged by teeth or endentulous areas of the upper and lower jaws of a patient. A circular opening is provided with in this middle region of the elongated body to allow the tube of a saliva and debris ejector to be positioned slidably therein, and within the mouth of a patient when the apparatus is being used. The elongated body is narrower between the flat surfaces of the bite pads for maximizing the visual field of a mouth to the person performing a dental procedure. The elongated body is deformable to ensure stable engagement between the teeth or endentulous region of the upper and lower jaws of a patient and the corresponding flat surface making up the bite pads of the elongated body.
