High performance acoustical cleaning apparatus for teeth.

THE DENTAL HYGIENE DEVICE INCLUDES A PORTION (12) OF BODY FROM AN END OF WHICH AN EXTENDED ARM (32) RESONATOR IS EXTENDED. THE ARM (342) IS MOUNTED FOR OSCILLATION ACTION AROUND A TORSION POINT (38), THROUGH ELECTROMAGNET (16) THAT WORKS IN THE BODY IN COMBINATION WITH TWO MAGNETS (34, 35) PERMANENT THAT ARE MOUNTED ON THE END REAR (31) ARM (32) RESONATOR. ON THE FRONT END (44) OF THE RESONATOR ARM A GROUP OF SOWS IS MOUNTED (47). THE ARM (32) IS DRIVEN SO THAT THE SOW POINTS OPERATE IN MARGINES OF AMPLITUDE AND FREQUENCY TO PRODUCE A SPEED OF SOW TIP GREATER THAN 1.5 METERS PER SECOND, WHICH PRODUCES AN IMPORTANT CLEANING EFFECT IN THE LIMIT OF THE POINTS OF THE SOWS.
