Abstract:

The dental hygiene apparatus includes a body portion (12) from one end of which extends a elongated resonator arm (32). The arm (32) is mounted for oscillating action about a torsion pin (38), by means of a electromagnet (16) in the body acting in combination with two permqanent magnets (34, 35) which are mounted on the rear 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 arm (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.
