  • Patent number: 4889490
    Abstract: A dental mask (A) is disclosed for protecting the facial area of a dental patient during dental work. The mask includes a mask frame (B) and a protective sheet (C). Latex (24) is used for protective sheet (C) having a medial opening (36) which fits about cheek retractors (12, 14) of mask frame (B). Support arms (26, 28, 30, and 20) support protective sheet (C) in a generally taut condition when the cheek retractors are inserted and retract the cheeks to expose an oral cavity (22) of the patient during dental work. Protective sheet (C) protects the surrounding facial area of the oral cavity, is inclined to provide proper breathing through the nose, and shields the eye area (42) against airborne contaminant particles which are likewise prevented from being deposited on the facial area of the patient.
