A method (300) for providing feedback to a user of an oral cleaning device (10). The method includes the steps of: (i) receiving (330), from a sensor (28) of the oral cleaning device, data about a plurality of orientations of the oral cleaning device within the user's mouth during a cleaning session; (ii) extracting (340), from the received data, information about one or more stable orientations of the oral cleaning device within the user's mouth during the cleaning session, where a stable orientation is an orientation of the oral cleaning device maintained by the user for a period of time above a threshold; (iii) fitting (350) the information about the one or more stable orientations of the oral cleaning device to one or more expected orientations; and (iv) providing (360) feedback to the user about the cleaning session based on an analysis of the fitted one or more stable orientations.

The present invention provides for oral care systems comprising: an appliance comprising a first and second plurality of nozzles, the appliance configured to be held in the mouth of a user with the first and second plurality of nozzles in fluid communication with one or more surfaces of the user's oral cavity; a source of gas; a source of liquid; and a fluid controller for directing entrained fluid to the appliance. Also provided are methods of cleaning, or otherwise providing benefits to, one or more surfaces of the oral cavity using a system of the present invention.

Disclosed is a dental implant handpiece, comprising an implant handpiece body (1), and a drill bit (2) disposed on the implant handpiece body (1). The implant handpiece body (1) is further provided with an image collector disposed close to the drill bit (2) and configured to acquire images of locations in the vicinity of the drill bit (2) in an oral cavity. In a whole treatment process, a dentist is free of double-handed operation and only needs to hold the dental implant handpiece with one hand. During the treatment process, images near the drill bit (2) are acquired in real time, thus the treatment situation is controlled in real time when each treatment action is executed, and the position and angle of the drill bit (2) may be adjusted at any time according to the images acquired by the image collector.

This invention is about a root canal activator and the activation method. It belongs to technical field of root canal treatment equipment. The eccentric wheel is connected with a oscillatory needle, which is composed of a needle head, a spherical joint and a connecting rod. The connecting rod is connected through a spherical joint to the ball-shaped slot of the eccentric wheel and therefore, a spherical pair is formulated to allow for a degree of freedom. There is a head cover made of soft rubber mounted at the top end of the outer shell. The oscillatory needle is mounted inside the soft rubber cover through a cylindrical joint, which has formulated a cylindrical pair and allows for five degrees of freedom in total.

An oral irrigator includes a base, a reservoir supported by the base and including a bottom wall and a port defined in the bottom wall, and a valve received in the port. The valve is movable between a first position in which the port is open to allow fluid flow from the reservoir to the base and a second position in which the port is closed by the valve. The valve includes a body, a cap extending from a first end of the body, a flange extending from a second end of the body opposite the first end, a sealing member positioned around the body adjacent the cap, and a spring positioned around the body adjacent the flange.

Embodiments of the invention provide a dental network including a portable dental laser station controllable within a remote access system. The dental laser station can include a dental laser, and a dental handpiece assembly coupled to or including the at least one dental laser. Some embodiments include a processor and a non-transitory computer-readable storage medium including a dental laser management process to exchange dentistry-related parameters between the dental laser station or components and a remote network. Some embodiments include a handpiece assembly structured so that any beam size on the output window or surface is greater than any beam size exiting at the input window or surface. Some embodiments include a laser power supply combination with at least one high voltage (HV) power supply, a coupled or integrated simmer supply, a direct current (DC) supply, and at least one laser configured with a power supply.

An orthodontic system and method for aligning at least one tooth of an upper jaw or a lower jaw of a patient. In the system and method at least one orthodontic appliance can be provided which may include at least one force exerting member for applying a force to move the at least one tooth, a tooth movement sensor for obtaining tooth movement data, and a tooth movement monitor for calculating at least one of the distance the at least one tooth has moved and a current position of the at least one tooth from the tooth movement data. An electronic control console may be operatively connected to the force exerting member and in data communication with the tooth movement monitor, for controlling the operation of the force exerting member using the at least one of the distance the at least one tooth has moved and the current position of the at least one tooth.

A dental instrument comprises a fluid driven handpiece in fluid communication with a valve; a source of fluid in fluid communication with the valve; and a controller in electrical communication with the valve and an actuator positioned on the handpiece. The actuator is configured to cause the valve to move between a first position in which fluid cannot flow from the source of fluid to the handpiece and a second position in which fluid flows from the source of fluid to the handpiece thereby driving the handpiece. The dental instrument may further comprise a second actuator in communication with the controller. The second actuator is configured to cause the valve to move between the first position in which fluid cannot flow from the source of fluid to the handpiece and the second position in which fluid flows from the source of fluid to the handpiece thereby driving the handpiece.

An assembly with a handpiece assembly configured to receive electromagnetic energy and fluid, and to selectively deliver the electromagnetic energy and/or the fluid to a target surface. The handpiece assembly includes a handpiece housing and a plurality of fluid lines extending through the handpiece housing. The plurality of fluid lines can transfer fluid from a proximal end of the handpiece assembly to a distal end of the handpiece assembly. A spray mixer can be positioned at the distal end that is coupled to fluid lines of the plurality of fluid lines. An air input port can be positioned at the proximal end that is configured to be coupled to an auxiliary air hose, and an air delivery channel can be coupled to the air input port, and can supply air to a tip of an exchangeable applicator that can be coupled to the distal end of the handpiece housing.

A processing device receives, from an image capture device associated with an augmented reality (AR) display, a plurality of images of a face of a patient. The processing device selects a subset of the plurality of images that meet one or more image selection criteria. The selection comprises determining, from the plurality of images, a first image that represents a first position extreme for the face; determining, from the plurality of images, a second image that represents a second position extreme of the face; selecting the first image; and selecting the second image. The processing device further generates a model of a jaw of the patient based at least in part on the subset of the plurality of images that have been selected.
