Adjustable, disposable dental prophy tool

摘要

An adjustable, disposable dental prophy tool includes an elongated cylindrical grip end body component and an elongated cylindrical cup end body component. The cup end body component is mounted on the grip end body component so that their major longitudinal axes are offset in non-parallel alignment. A housing for a cleaning and polishing cup drive element is mounted at the outer end of the cup end body component. A drive element is mounted in the housing for rotation about an axis which extends laterally of the longitudinal axis of the elongated cup end body component. The cup end body component is fully rotatable for 360 DEG about its own longitudinal axis relative to the grip end body component. The tool also includes axial locking structure holding the body components together to prevent relative axial movement thereof. The tool also includes releasable angular locking structure selectively inhibiting relative rotation of the body components.
