Abstract

In a preferred embodiment of the invention, a dental scaler for the cleaning of teeth in which the scraper is an air-driven vibrator having a scraper mounted on a distal end of a rigid tubular device, with the rigid tubular device being mounted within a resilient support permissive of vibrations of the rigid tubular device and the vibrations of the tubular device being brought about by the exiting of air onto an air-cushioned rotary wheel mounted around the tubular device rotatably, the rotation thereof resulting from the force of the air from preferably a plurality of ports permitting the air to exit from the ports against the inner surface of the air rotary wheel, and the rotation of the rotary wheel bringing about the vibrations which are imparted to the rigid shaft, while the firmly supported tubular shaft within the resilient support structure thereof itself amplifies the magnitude of the vibrations by itself vibrating and transmitting its vibrations back to the rotary wheel, the outlet ports from the tubular device being angled laterally sidewardly in a direction transverse to the longitudinal axis of the tubular device in a preferred embodiment, as well as the ports being angled in an axial direction relative to the longitudinal axis of the tubular device thereby enhancing the optimal flow of air from within the tubular device into the space between the exterior surface of the tubular device and the inner radius surface of the air wheel and preferably also there being similar angular passages between the tubular device and the outlet portions of the air wheel at end-points of the air wheel axially.
