A method for producing a mouthpiece toothbrush is provided, in which at least one dental arch of the patient for whom the toothbrush is intended is scanned to generate scan data, or an impression of the dental arch is made. Based on the scan data or the then digitised impression, the dental arch space occupied by the dental arch is recorded. A bristle space is constructed around the at least one dental arch, and a toothbrush moulded piece is calculated, the surface of which facing the dental arch is determined by the dental arch space plus the bristle space. The surface is covered with a bristle carpet.

In one embodiment, the invention may be a teeth cleaning device including: a first support structure comprising a first dentature channel configured to receive at least a first portion of a dentature of a user; a plurality of teeth cleaning pads located within the first dentature channel; a plurality of air bladders operably coupled to the teeth cleaning pads; an air-flow subsystem operably coupled to the air bladders; and a control unit operably coupled to the air-flow subsystem, the control unit configured to: (1) pressurize the air bladders with external air in a pressurization mode; and (2) transfer air between select ones of the air bladders in a cleaning mode.

The present invention relates to the manufacturing of a bristled pad for a mouthpiece toothbrush, a bristled pad, the manufacturing of a mouthpiece toothbrush with such a bristled pad, and a mouthpiece toothbrush. The bristled pad is manufactured from a prefabricated foil and prefabricated bristles. The prefabricated bristles are attached to the prefabricated pliable foil of at most 700 μm by fusing the fixed ends of the bristles with the foil. In the method of manufacturing the mouthpiece, the bristled pad is attached to the body of the mouthpiece.

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.

The invention provides for an oral treatment unit, or an assembly of a plurality of oral treatment units, for confining an electromagnetic field having a frequency in the range of 100 kHz to 300 MHz and adapted to be inserted into an oral cavity, which may form part of an oral cleaning device in combination with a base unit, including a first cleaning element coupled to the oral treatment unit. The oral treatment unit further includes a material structure coupled to the oral treatment unit adapted to receive an initial electromagnetic field and output a focused electromagnetic field, wherein the material structure has a passive electromagnetic field focusing function, which focuses the received initial electromagnetic field in the near-field region of the material structure. A further aspect of the invention provides for an oral treatment unit, or an assembly of a plurality of oral treatment units, for confining and modulating an electromagnetic field having a frequency in the range of 1 MHz to 300 GHz and adapted to be inserted into the mouth, which may form part of an oral cleaning device in combination with a base unit, including a first cleaning element coupled to the oral treatment unit. The oral treatment unit further comprises an electromagnetic field focusing element adapted to receive an electromagnetic field having an initial frequency and output a focused electromagnetic field. The electromagnetic field focusing element comprises a first material structure having a first passive electromagnetic field focusing function, which confines the modulated electromagnetic field at a given distance from the first material structure by performing one or more of: an attenuation rate control function in the near-field region of the first material structure; or a propagation direction modification function on the electromagnetic field. The electromagnetic field focusing element has a modulation function that modulates the confined electromagnetic field, thereby generating a modulated electromagnetic field.

A teeth cleaning travel kit includes toothbrushing mouthpiece that has two inverted channels dimensioned to receive upper and lower bites of dental arches of a user, the channels being integral with one another. Teeth-cleaning bristles inwardly project within the two inverted channels to bear inwardly against teeth and gums of the user, wherein the channels and teeth-cleaning bristles are configured such that mastication produces relative brushing movement of the teeth-cleaning bristles over the teeth and gums. An oral hygiene promoting product is attached to one of the two inverted channels and the teeth-cleaning bristles that is released by action of the user's mouth. The teeth cleaning travel kit also includes a vessel that contains a rinsing fluid and kit packaging that contains the toothbrushing mouthpiece and vessel.

An orthodontic remodeling device, wherein the bite plate is modified to have textured teeth and gum facing surfaces so as to provide cleaning, massaging or acupressure effect when in use.

Automatic toothbrushes are disclosed herein. A toothbrush configured in accordance with embodiments of the present technology can include, for example, a handle and a mouthguard coupled to the handle. The mouthguard can be configured to be positioned within a mouth of a user over multiple teeth of the user. A brush assembly having a plurality of bristles can be removably positioned within the mouthguard for engaging and cleaning the teeth of the user. A motor can be disposed within or coupled to the handle and configured to articulate the brush assembly within the mouthguard.

An oral cleaning unit, e.g. a head for an oral cleaning and/or treatment device, includes electrodes for generating an RF field for providing an oral cleaning and/or treatment function. The unit includes at least a first and second protruding structure, which protrude in a same general direction away from a base or support structure. Each comprises one or more electrodes. The protruding structures are arranged facing one another and separated by a space or gap which is configured so as to be able to receive a tooth pushed or inserted therein between the first and second protruding structures, and with the protruding structures extending on either side of the tooth, i.e. straddling the tooth. This allows the RF electrodes comprised by the protruding structures to reach to a location at least part way down side faces of the tooth, closer to interproximal spaces, enabling interproximal spaces to be better cleaned, and optionally also to be sensed using RF energy/fields interacting with dental features, when the electrodes are suitably driven by an RF signal.

An oral care device (8) for use in aiding delivery of a substance for an oral treatment purpose within the mouth. The device comprises a field generator (16) which is adapted to generate a field (20) for exerting a force on particles (20) susceptible to the field to guide movement of the particles to a desired location. When operated in the mouth, this allows oral treatment particles to be quickly, safely and efficiently distributed within the mouth to the correct locations for performing the oral treatment function.
