A device for generating oscillations for dental applications has an actuator connectable to an energy source and provided with a lifting member. The actuator is connected via a hydraulic linkage to the working device. Via the hydraulic linkage the oscillations generated by the actuator are transmitted onto a workpiece, for example, a crown. With this embodiment it is possible to transmit the mechanical oscillations generated by the actuator onto the crown so that the binder between the crown and the tooth stump is evenly distributed and compressed in a short period of time.
