Profile: Isolite Systems designs & markets dental devices. Our dryfield illuminator is a dental device that combines the functions of light, suction, and retraction into a single tool. It provides increased visibility in the working field, quick reliable isolation and moisture control, faster dental procedures, and offers improved ergonomics for dentists, hygienists & dental assistants. The new shape and design of the medium DV mouthpiece allows for more complete tongue retraction & a better fit in a patient's mouth. Its expanded cheek shield shape provides improved suction that goes deeper into the vestibule. The new design also provides additional suction capacity within the bite block itself, assuring that saliva does not pool behind the mouthpiece.
