ABSTRACT:
A turbine insert for insertion into a head-housing of a turbine elbow for dental use includes a rotatable axle which has a plurality of turbine blades disposed thereon. One of the axle-ends is adapted to receive a dental tool and a threaded cap may be attached to the head-housing. Support means are provided for receiving the rotatable axis, and the other axle-end is rotatably supported in the threaded cap through the support means. A protective sleeve which surrounds the turbine blades is formed with an opening for the passage of compressed air for driving the turbine, and at least partially surrounds and rotatably supports the dental-tool receiving axle-end through the support means.
