HIGH PERFORMANCE ACOUSTICAL CLEANING APPARATUS FOR TEETH

摘要

The dental hygiene apparatus includes a body portion (12) from one end of which extends an elongated resonator arm (32). The arm (32) is mounted for oscillating action about a torsion pin (38), by means of an electromagnet (t6) in the body acting in combination with two permanent magnets (34, 35) which are mounted on the rea r end (31) of the resonator arm (32). On the forward end (44) of the resonator arm (32) is mounted a set of bristles (47). The ar m (32) is driven such that the tips of the bristles operate within ranges of amplitude and frequency to produce a bristle tip velocity greater than 1.5 meters per second, producing a significant cleansing effect beyond the tips of the bristles.
