A light curing dental system comprising a light emitting tray that precisely distributes an optimal amount of curing light energy to internal, external and extra oral portions of the dental arch to cure a dental material. The light curing dental system generally includes a light source, a light emitting dental tray, an activation module and a photocurable dental material.

Disclosed is an oral caring device. The oral caring device includes a handle part and a caring head part, the handle part is configured to be suitable for hand-holding, the caring head part includes a flushing stem, and a brush head structure, arranged at the second end of the flushing stem. According to the technical solution of the present disclosure, the oral caring device has a synchronous flushing function to improve a cleaning effect and user experience.

An apparatus and method are used to deliver an electrical current to, through or across gingival tissues of a mouth in order to achieve a number of therapeutic, prophylactic, cosmetic, and or regenerative benefits. These benefits include killing or modifying oral microbes, increasing oral vasodilation, reducing oral biofilm, improving oral blood circulation, reversing oral bone resorption, promoting oral osteogenesis, treating gum recession, and fostering gingival regeneration. Other benefits include the treatment of gingivitis, periodontitis, and oral malodor, and other systemic diseases correlated with oral pathogens. Use of systems and methods according to the present invention may effectively tighten epithelial contact with one or more teeth (e.g., by the junctional epithelium and/or the sulcular epithelium) and/or cause a tightening of the oral epithelium, thereby improving an appearance of a human smile.

An electric toothbrush is disclosed, having a handle including a drive motor and a head portion removably coupled to the handle. The head portion includes a brush, an exit port fed by an internal irrigation lumen, and a drive shaft operatively connecting the drive motor to the brush. A disposable irrigant reservoir is removably coupled directly to the head portion. The irrigant reservoir is in fluid communication with the internal irrigation lumen of the head portion. The head portion is configured to be replaceable with respect to the handle, and the irrigant reservoir is configured to be replaceable independent of the head portion. In some examples, the irrigant reservoir is a disposable bulb (e.g., a capsule), and is positioned such that the user can hold the handle while also squeezing the reservoir with the same hand. In some examples, the toothbrush head includes a suction mechanism.

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.

A system comprises a dental tray comprising an array of fixed focus cameras, wherein each fixed focus camera of the first array of fixed focus cameras has a fixed position and orientation relative to one or more other fixed focus camera of the array of fixed focus cameras. The system further comprises a processing device to receive a plurality of images generated by the array of fixed focus cameras, stitch the plurality of images together based on calibration data specifying predetermined image stitching parameters for combining the plurality of images, wherein the predetermined image stitching parameters are based on predetermined fixed relative positions and orientations of fixed focus cameras from the array of fixed focus cameras, and generate a three-dimensional model of a plurality of teeth based on the stitched plurality of images.

A heating device for heating a dental material. The heating device has a body and a socket. The socket is removably received within the body and has a socket wall that forms a receptacle for positioning a container for the dental material therein. The body has a light source for emitting light toward the socket wall in a direction toward the receptacle. The socket wall is at least partially transmissive for infrared light. The heating device allows for heating the dental material within the container.

An intra oral removable orthodontic assembly which influences teeth alignment. The assembly comprises; a intraoral attachment fitted to a seating unit and in use, held in place by intraoral engagement of the attachment with crowns of teeth of a wearer. The intraoral attachment is shaped to at least partially conform to at least a dental arch. The seating unit includes a power source, a PCB controller and a source of vibration transmissible to the attachment. The seating device vibrates in response to the source of vibration at a selected frequency between 60 Hz-130 Hz inducing a response in a selected tooth or group of teeth of a wearer. The attachment includes a working head having an array of displaceable formations responsive to said vibration and arranged to engage said teeth.

The charging stand for a care apparatus according to the present disclosure includes a fifth terminal connected to a first terminal, a sixth terminal aligned with the fifth terminal and electrically connected to a second terminal, a first cover having a cylindrical shape that stores the first terminal, a second cover having a cylindrical shape that stores the second terminal, a fifth cover having a cylindrical shape that stores the fifth terminal, and a sixth cover having a cylindrical shape that stores the sixth terminal. A shape of an input connecting portion formed by the fifth cover and the sixth cover is different from a shape of an output connecting portion formed by the first cover and the second cover.

The invention relates to an electric toothbrush provided with longitudinal, also called axial, oscillating movement that occurs at the active end of the bristle plumes, or nylon filaments, without the end or tip of the brush causing potentially traumatic blows, which represent an undesired risk, as still occurs according to the existing prior art.
