Abstract

An improved therapeutic ultrasonic toothbrush for daily removal of soft plaque, disruption of the bacterial colonization process within the gingival pockets, the reduction of the recurrence of aphthous stomatitis, and for the acceleration of the healing of the sores of the oral cavity. The device includes a handle constructed of a rigid material, a battery pack, an electronics driving module, a piezoelectric member, and a removable brush head. The piezoelectric crystal resonates, expands and contracts volumetrically, in tune with the frequency supplied by the electronics driving module and thereby converts the electronic energy into sound-wave energy. The sound waves loosen up the bound between the bacterial plaque and the teeth and disrupt the bacterial colonization process within the periodontal pockets and the mucous membranes of the oral cavity. Ultrasonic emission from the back side of the brush accelerates healing of sores of the oral cavity. A variation of the device provides directional control of the ultrasonic output to maximize either the dental or the dermatological benefits of the brush.
