A headgear can be worn on a user's head to adjustably fix a mouthpiece inserted in an oral cavity. The headgear includes: a front pad brought into contact with and pressed against a front pressure point of an outer surface of the buccinator between the zygomatic bone and the mandible in the face region; one or more rear pads brought into contact with and pressed against one or more rear pressure points so that a resultant force becomes a reaction force paired with a pressing force of the front pad, in a region from the top to the back of the head; a frame fixing the front pad and the rear pads; a front horizontal bar fixed to the frame at a position in front of the lip region of the head; and an adjustment part installed on the front horizontal bar to mount the mouthpiece.

The invention provides a unitary cordless dental drive apparatus in a first embodiment having a handpiece with a cantilever arm 18 extending outward and positioned to allow a dental nose cone 26 to be connected. An activating switch 20 is located at the free end of the cantilever arm 18 in a position that is convenient for manipulation by a user. In a second embodiment, a contactor 22 is mounted below the cantilever arm 18 to contact the nose cone 26 when pressed. In a third embodiment, a standard dental office foot pedal 90 is connected to a wireless transmitter 80 for sending a signal to a receiver 92 located within the handpiece 70 for activating the handpiece 70.

A motor-driven fluid, semi-fluid, or semi-sold material dispensing apparatus including a housing; a plunger/drive rack; an electric motor mounted transverse to the plunger/drive rack; a gear system mechanically coupled to the electric motor and configured to drive the plunger/drive rack, wherein the gear system includes a rack drive gear operatively engaged with the electric motor, the rack drive gear includes a plurality of saw tooth type gear teeth, the rack drive gear teeth being configured to engage with corresponding teeth disposed on the plunger/drive rack; and wherein, the electric motor and gear system are housed in a main body portion of the housing.

An oral hygiene device comprises a housing having an outside mouth portion and an inside mouth portion, at least one energy delivery element disposed in or on the inside mouth portion, configured to deliver energy to one or more teeth of a subject, a controller disposed in the outside mouth portion electrically connected to the at least one energy delivery element, an energy storage unit disposed in the outside mouth portion, and a sleeve removably connected to the inside mouth portion of the housing, the sleeve having upper and lower channels configured to accept the upper and lower teeth of the subject. A method of using an oral hygiene device and a method of administering an oral hygiene treatment are also described.

A wearable controller for a dental handpiece system and a dental handpiece system are disclosed. The wearable controller includes a wearable body. The wearable body includes an input and a display, the input and the display for displaying a graphical user interface (GUI) to an operator providing a plurality of operating selections. A battery is electrically connected to the input and the display for powering the input and the display. A reservoir is secured to the wearable body. An output is electrically connected to the input and the display for receiving an indication of an alert.

The care unit according the present disclosure includes a care apparatus that includes a storage battery and a charging stand that is electrically connected to the care apparatus, and the care unit includes a first terminal, a second terminal, a third terminal, a fourth terminal, a first cover, a second cover, a third cover, and a fourth cover. When the care apparatus is held in a predetermined position of the charging stand, the third cover is not in contact with the first cover in a radial direction orthogonal to an insertion direction of the first cover, and the fourth cover is not in contact with the second cover in a radial direction orthogonal to an insertion direction of the second cover.

A multifunctional dental liner applicator dispenses tooth liner and a stream of air while illuminating the working dental area. The applicator includes a body and a head that is removably attached to a distal end of the body. The head supports a nozzle that is configured to be inserted into a void of a prepared tooth. A liner button on the body controls a valve for dispensing liner out of the nozzle. An air button controls airflow out of openings adjacent the nozzle for drying an area that is receiving liner. Fiber optic fibers extend from a button controlled light source housed in the body to openings adjacent the nozzle for illuminating the working area.

Disclosed herein are embodiments for a handle for securing a patient's mouth in place while an oral procedure is performed. A handle includes a handle head extending from a handle body, the handle head comprising exterior border bumpers to the sides. An indented portion lies in between the border bumpers, the indented portion having grooves oriented substantially perpendicular to a length of the border bumpers. The indented region is configured to receive a patient's teeth and lock the patient's mouth open by preventing the teeth from sliding off the surface of the handle head. With the patient's mouth securely open, a caregiver may then use a second tool (e.g., a toothbrush, flosser, tongue cleaner, etc.) for cleaning the patient's mouth or performing any other oral procedure.

A wireless teeth whitening system includes a mouthpiece that is devoid of any electrical circuitry so that it may easily be cleaned and sterilized. A control module may be coupled to the mouthpiece. This module has an electrical circuit board with LEDs and heating elements mounted on it. When the control module is coupled to the mouthpiece, the system may be used to whiten teeth. The control module includes a battery that may be inductively charged, and may be wirelessly controlled via Bluetooth from a mobile application.

A pump body of an oral irrigator includes a mount, a motor disposed at a rear end away from the mount, a pinion disposed on a shaft of the motor, an annular gear disposed on a shaft member to mesh with the pinion, a cam disposed in the annular gear and adjacent to one side, a linkage secured to the cam, front and rear plungers disposed on a front end of the linkage, and a cylindrical tube disposed on the plungers in the mount. The rotation of the cam only allows the linkage to repetitively moves in a back-and-forth linear motion. Wear between the plungers and the cylindrical tube is decreased to a minimum and leakage is prevented.
