Abstract
A dental handpiece, consisting of a gripping sleeve part with a built-in air motor for the drive of a treating implement which is supported within the gripping sleeve part. The gripping sleeve part has a detachable connecting member associated therewith; and the air motor has a control device possessing a handgrip associated therewith for changing the direction of rotation of the air motor; and wherein the connecting member is further provided with two passageways having outlet orifices connectable with the air motor for, respectively, the infeed of driving air and the discharge of exhaust air. For collective gripping sleeve parts which are brought into exchangeable engagement with the connecting member, it is necessary to provide only a single control device for changing the direction of rotation, which results in a simple mounting of bearing support for the gripping sleeve parts.
