Abstract: A disposable hand tool for performing dental and other health care procedures in which the entire tool is thrown away and disposed of after use with a single patient. The tool is made of relatively inexpensive materials such as plastic, and since durability and re-use are not requirements the operating mechanism can itself be constructed of disposable materials, including non-metallic materials. In the embodiment described herein, the disposable hand tool has a rotatable working member such as a rotatable buffer for polishing and cleaning teeth known in the dental profession as a prophylactic angle or cup, a rotatable burr also for use by dentists, and the like. The rotatable operating mechanism includes a small turbine of plastic or other disposable material mounted for rotation in a hand held housing which is also made entirely of disposable material and connectable to a hose which in turn is connected to a source of compressed air to drive the turbine.

Abstract: A disposable rotary tool assembly for cleaning teeth comprising what is known in the dental profession as a prophylactic angle, a small cup-like member made of rubber or similar material having a frusto-conical shape which is placed against a patient's teeth and rotated for cleaning and polishing, and a disposable operating assembly for rotating the same which is connected to a dentist's air syringe and powered by pressurized air instead of being connected to the dentist's hand piece as at present which requires a relatively expensive shaft driven connector, not practical to dispose of after each use with a single patient.
