Dental Cleaning Device

A mouthpiece for simultaneously brushing at a plurality of dental positions, the mouthpiece comprising:

• a body provided with at least one recess, wherein the at least one recess has a curved length direction extending parallel to the z-axis, and a U-shaped cross-section transverse to the length direction, the at least one recess being configured for encompassing, viewed in the curved length direction, a plurality of dental positions;
• wherein the body comprises a recess wall delimiting each of the at least one recess;
• a plurality bristles attached to the body, wherein each of the plurality of bristles has a fixed end which is, at the recess wall, attached to the body, wherein each bristle extends from the fixed end, into the recess, towards its free end, which is arranged in the recess;
• wherein a system of three mutually orthogonal axes is defined, comprising an x-axis, a y-axis, and a z-axis, the z-axis being a curved axis following the contour of a dental arch, the x-axis and y-axis being perpendicular to each other and defining an xy-plane which is flat and perpendicular to the curved z-axis;
• wherein the body is configured to subject, when said plurality of dental positions is encompassed in the recess, a plurality of said fixed ends of said bristles reciprocatingly to a first back and forth pivot movement around a first pivot axis, a second back and forth pivot movement around a second pivot axis and a back and forth translation movement along a translation axis, the first pivot axis, the second pivot axis and the translation axis being mutually perpendicular, the first pivot axis being parallel to the z-axis, and the second pivot axis and translation axis extending in the xy-plane.

• and
• wherein the body comprises a recess wall delimiting each of the at least one recess,
• wherein the recess wall is lined with a plurality of bristles extending from the recess wall into the recess;
• a meshwork lying against the recess wall or fixed to the recess wall, the meshwork formed by nodes and mesh members, each said mesh member extending from one said node to another said node, each said node connecting at least three said mesh members to each other, and wherein each node carries one or more of said bristles or a tuft of said bristles.
