Abstract:
1. A treatment device for teeth comprising: a treatment head that is removably fastened to a handpiece, the treatment head includes a head piece comprising bristles and an electromechanical transducer in the head piece for producing mechanical oscillations or waves to be transferred to a treatment area, wherein all of the bristles of the head piece are directly connected on one end to the electromechanical transducer for transfer of the mechanical oscillations or waves in an axis direction parallel to a longitudinal extension of the bristles so that the mechanical oscillations or waves produced by the electromechanical transducer are transferred directly and undamped to the bristles, wherein all of the bristles of the head piece are directly connected on one end with the electromechanical transducer so that the mechanical oscillations are transferred directly and undamped to each bristle and each bristle forms one element for transfer of the mechanical oscillations to a free end of each bristle and wherein the handpiece comprises a vibrator comprised of a miniature motor, the vibrator is activated when the handpiece is switched on and the vibrator serves to mechanically or haptically indicate that the treatment device is activated.
