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.

The present invention relates to an electrochemical device for releasing ions, comprising an electrical circuit comprising a first electrode and a second electrode adapted for providing a galvanic cell when the electrodes are exposed to a fluid constituting an electrolyte, and a boost converter adapted for amplifying a potential generated between the first and the second electrode. The electrical circuit further comprises a third electrode connected with an output side of the boost converter, wherein the second and the third electrode constitutes an electrolytic cell powered by the galvanic cell when the electrodes are exposed to a fluid. The present invention further relates to devices, such as a toothbrush or a shaver, adapted for being used in connection with a fluid, comprising such electrochemical device for releasing ions.

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 care device has a field generator adapted to generate an electric field in a mouth of a user, responsive to an input control signal. The electric field is for imparting a force upon particles forming a biofilm to be removed by the oral care device or upon cleaning agent particles. A cyclic control signal is generated for intermittent generation of an electric field at a first RF frequency. The use of an intermittent generation of an RF electric field means the force applied to particles (in particular polarized particles) by the field is itself cyclic. The cyclic nature of this applied force is found to be more effective in the disintegration of a biofilm to be removed, and hence makes subsequent mechanical removal, e.g. by brushing, easier.

A vibrating toothbrush and an eccentric shaft are proposed. The vibrating toothbrush includes a head in which bristles are planted, and a handle from which a head coupler protrudes, the head being detachably coupled to the head coupler. The toothbrush includes an electric motor accommodated in the handle to generate rotating force; and an eccentric shaft rotatably connected to the electric motor, at least a portion thereof being eccentric to generate vibration and thereby transmit vibration to the head coupler. The eccentric shaft includes a motor fixing part connected to the electric motor; an eccentric weight configured to be offset from a rotation center of the electric motor; and a rotating shaft formed of a metal material, and connecting the motor fixing part and the eccentric weight.

The present disclosure provides a brushhead for an power toothbrush detachably attached to a handle of the power toothbrush, the handle including a vibrating drive shaft, the brushhead comprising: a main body defining a receiving cavity which is configured to receive at least a portion of the vibrating driving shaft, the main body including a cavity wall substantially surrounding the receiving cavity and an end connected to the handle, with an opening which is defined in the end of the main body in air communication with the receiving cavity, so that the vibrating driving shaft is capable of being inserted into the receiving cavity through the opening; and an engaging assembly mounted in a side wall of the main body, the engaging assembly comprising an elastic member, which is made by metal material; wherein, a recess is defined in the outer surface of the side wall, the elastic member is deformably received in the recess, the elastic member is elastically deformed by force provided from the vibrating drive shaft when the brushhead is attached to the handle of the power toothbrush.

An oral care system comprising: a. an electrical motor b. a base assembly comprising: i. an elongated base-assembly main body defining an elongate axis; and/or ii. a battery or a battery compartment optionally including electrical contacts for a battery, the battery and/or the battery compartment being electrically wired to the electrical motor; and c. a head assembly is disclosed herein. Methods and kits are also disclosed.

An ultrasound applicator having spatially extended functionality to treat various oral and dental diseases. The applicator incorporates a multi directional ultrasound transducer system, which spatially irradiates the oral cavity with ultrasonic pressure waves, operational to simultaneously treat and destroy disease causing bacteria and bacterial chains on the gums and the inside surfaces of cheeks and lips, providing relief from Gingivitis, Recurring Aphthous Stomatitis, Lichen Planus, and Mucositis. A motorized version featuring sonic frequency orbital vibration of the applicator is described.

An electrical appliance for personal care includes a handle with a longitudinal axis, and a plug-on part which can be attached to the handle, wherein a vibration unit having an electric motor and an eccentric element is arranged in the handle, wherein a plug-like coupling structure protrudes from the handle, which plug-like coupling structure forms an interface with a substantially mirror-inverted socket-like coupling structure of the plug-on part, wherein the interface has at least two stages with different circumferential geometry, wherein at least one of the stages has a rotation-preventing device between the handle and the plug-on part, and wherein a stop surface of the handle for the plug-on part extends obliquely with respect to the longitudinal axis of the handle.

Hands-free systems, devices and methods, adapted for brushing, cleaning and treating all of a user's teeth simultaneously, are provided. In some embodiments, such a device comprises brushes for cleaning all of a user's teeth simultaneously. In some embodiments, such a device includes a generally U-shaped channel(s), accepting, cleaning and/or treating all of a user's teeth simultaneously. Customized fluid jets within such devices are provided, introducing dentifrices and other treatments into the channels. In some embodiments, compartments and cartridges with a proprietary form factor for delivering dentifrice and other treatments and for disposing of waste without mess are provided. In some embodiments, data are gathered, analyzed and serve as the basis for a treatment plan, which may then be carried out by the system(s), device(s) and method(s), over time.
