ABSTRACT:
A dentistry hand piece is provided wherein a rotation of a drive motor is converted into an oscillation of a receiving part for a dentistry tool. The conversion of the rotation into the oscillation takes place in an attachment head (3) of the hand piece. The longitudinal axis (51) of the receiving part (8, 8') for the tool in the attachment head (3) is arranged at an angle (preferably approximately at right-angles) to the longitudinal axis (53) of the neck area (1) of the hand piece adjoining the attachment head (3), and the plane of oscillation of the receiving part (8, 8') for the tool is substantially perpendicular to the longitudinal axis (51) of the receiving part (8, 8').
