  • Spray shield
    Patent number: 4850868
    Abstract: The apparatus comprises a tubular member that is adapted to be attached to the working end of a dental handpiece and is used to contain and direct material dispensed from the handpiece in order to reduce the amount of airborne particles emitted into the atmosphere by the handpiece and to accurately direct the dispensed material to the desired area. The apparatus is adapted to provide a reference point for the practitioner in establishing the optimum working distance of the handpiece from a particular working area in the mouth when the handpiece is used. An improved dental handpiece using the apparatus of the invention and a method of using the apparatus are also provided.
