High-powered automatic electromechanical toothbrush
First Claim
1. A high torque and high power sonic automatic oral toothbrush for cleaning teeth and massaging gums and being designed and so constructed and arranged to produce acoustic pressures to dislodge bacterial and microbial plaque under the gumline and in pockets without physical contact between the plaque surface and the bristle tips while maximizing the shine and whiteness of the teeth, and, at the same time, stimulating the gums to prevent and arrest periodontal disease, a body member which includes a shaft mounted for oscillating motion, a set of bristles having free end tips, the set of bristles being located close to one end of the shaft;
- and means in the body member for moving the shaft and hence the set of bristles such that the amplitude of the bristle tips do not vary by more than ±
30% when an applied load on the bristle tips increases from 0 to 350 g (3.5 N), such amplitude being sufficient to produce a remote sonic cleansing and massaging action with a coupling fluid at a location at least 2 mm beyond the bristle tips.

Abstract
A sonic toothbrush and method produces acoustic pressure. A predetermined bristle tip velocity is generated under applied load. A predetermined acoustic pressure is produced under applied load. A predetermined shear stress is produced and predetermined mechanical power is produced. Bacterial and microbial plaque under the gumline and in pockets is dislodged without physical contact between the plaque surface and bristle tips.
