The IsoliteTM Dryfield Illuminator fully illuminates a patient's mouth from the inside out making it easier for dentists to see and work. A thermo-plastic clear elastomer is formed into a soft structural mouthpiece that allows transmission of light, retraction of the tongue and cheek, a built-in provision for bite block and continuous aspiration from the oral cavity. Because of hygiene issues, the mouthpiece is disposable. One-piece injection molding kept cost low.
