US 12,427,006 B2 · Mouthpiece for a dental cleaning system and the dental cleaning system

Abstract

The invention provides a mouthpiece for dental cleaning system and the dental cleaning system itself. The mouthpiece has a base and inner and outer arches. An actuator is for applying motion to the inner arch and/or the outer arch, relative to the base. A coupling arrangement converts motion of one of the inner and outer arches in one direction relative to the base to motion in an opposite direction relative to the base of the other of the inner and outer arches. By forming the mouthpiece as a central stationary base enveloped by two contour-following and moving arches, an anti-phase brushing motion at opposite tooth sites along the tooth arch is enabled, giving increased reach toward the molars as well as a reduction in device vibration in the mouth.

Dependent claims

A mouthpiece for a dental cleaning system, comprising:

a base;
an inner arch for positioning adjacent an inner surface of teeth of a jaw of a user;
an outer arch for positioning adjacent an outer surface of the teeth of the jaw;
an actuator;
and
a coupling arrangement adapted to couple the base, the inner arch and the outer arch, the coupling arrangement comprising coupling members extending between the inner and outer arches, the coupling members connecting to the base at a location between the inner and outer arches, wherein the coupling arrangement couples to adjacent regions of the inner and outer arches, and converts motion of said region of one of the inner and outer arches in one direction relative to the base to motion in an opposite direction relative to the base of said region of the other of the inner and outer arches.
