The invention relates to a cartridge for storing, discharging and applying a dental compound, in particular a paste for preparing and drying the gingival sulcus (sulcus gingivae) during dental impression taking. The invention relates to a cartridge (1) for storing, discharging and applying a dental compound, comprising a container (2), which has a hollow chamber (4) for accommodating the dental compound, and a cannula (3). The hollow chamber (4) comprises an outlet opening (5) and an actuator opening (6) opposite the outlet opening (5), and the cannula (3) is fluid-connected to the outlet opening (5), is arranged on the container (2) and is straight in the starting state. The cartridge is characterised in that the cannula (3) is made of plastic and is plastically deformable under standard conditions with the application of manual force in such a manner that a permanent bend by an angle of at least up to 65 in comparison with the starting state can be achieved without buckling the cannula (3).

A dispensing apparatus includes a body, two inlets for flowable masses and two outlets through which the flowable masses can be dispensed, with one inlet being connected to one outlet and the other inlet being connected to the other outlet through the body. The two inlets are spaced apart from one another by a first spacing and the two outlets are spaced apart from one another by a second spacing, and with the second spacing being larger than the first spacing. A connection ring engages the body and is pre-mounted to the body. The dispensing apparatus is configured to be non-releasably connected to a two-component cartridge via the connection ring for the supply of the flowable masses to the inlets.

Examples of a dental orthotic guard and protection device are disclosed. The device is re-usable and can be used by users with or without braces. The protection device comprises a body shaped to correspond to user's dental arch and an aerating trough formed in the body such that it rises upward from its surface. The aerating trough has a plurality of openings to allow fluid circulating in and out through the trough to prevent fluids accumulating on a surface of the protector and provide free air flow. The dental orthotic can further comprises a U-shaped guard with top and bottom surfaces that are substantially flat such that the guard sits flat on top of user's teeth to provide fluid flowing between the user teeth and the guard. The dental protector and guard can be connected as a single piece for use as dental orthotic device in small children.

A dental dispenser that receives a cartridge and a blunt tip applicator for the safe and controlled extrusion and placement of dental materials such as non-injectable anesthetics.

A dispenser for dispensing a liquid such as a tooth whitening gel can include a plunger and a housing having a first chamber that receives a first arm of the plunger and a second chamber that receives a second arm of the plunger. The housing can further include a first channel in fluid communication with the first chamber, a second channel in fluid communication with the second chamber, and a third channel formed at an intersection of the first and second channels. The housing can further include a static mixer than mixes a first liquid from the first chamber with a second liquid from the second chamber. The plunger may be disposed along a first axis and the third channel may be disposed along a second axis that intersects the first axis at an angle of between 10 and 170.

A system for remote orthodontic treatment and assessment includes an application server to receive multiple images that represent the teeth of a user and receive an approval from a staff device that indicates a person has approved the images for assessment by a provider. The application server is further receive another approval from a provider device that indicates that the provider has assessed fitness of the user for treatment. The application server may receive the images from a user device. The application server may receive an approval from the provider device that indicates that a treatment plan is approved. In response to receiving the approval of the treatment plan, the application server optimizes 3D models of the treatment plan and provides a visualization of the 3D models to a user device.

Systems and methods of remote orthodontic treatment include receiving a plurality of images from a customer where the plurality of images represent teeth of the customer, receiving a first approval from a staff computing device where the first approval is indicative of a staff user approving the plurality of images for assessment by a dental professional, receiving a second approval from a provider computing device where the second approval is indicative of the provider approving a fitness of the customer for treatment, generating, in response to receiving the second approval, a treatment plan including a series of steps to reposition at least one tooth of the teeth of the customer, and manufacturing one or more aligners based at least in part on the treatment plan where the aligners are specific to the customer and are configured to reposition the at least one tooth of the teeth of the customer.

A dental impression kit includes a container including a dental assembly that includes a dental tray and a predetermined amount of base putty and catalyst putty, where the base putty and the catalyst putty are mixable to form a putty mixture, and the predetermined amount of base putty and catalyst putty are amounts sufficient such that the putty mixture can be positioned in the dental tray for creating a dental impression. The dental impression kit includes instructions instructing a user to administer the dental assembly to create the dental impression, where the dental impression provides information necessary to manufacture a plurality of dental aligners specific to the user and being configured to reposition one or more teeth of the user, and where the predetermined amounts of the base putty and the catalyst putty are in the range of 0.5 ounces and 1.5 ounces.

A method includes receiving representations of a first set of dental impressions including a first dental impression of an upper dental arch of a user and a second dental impression of a lower dental arch of the user having been created using contents from an initial dental impression kit sent to the user, identifying a defective dental impression, sending a retake dental impression kit to the user where the retake dental impression kit includes a set of dental trays consisting of dental trays corresponding to the dental arch associated with the defective dental impression, receiving representations of a second set of dental impressions of the dental arch associated with the defective dental impression, and manufacturing, based on the second set of dental impressions, a plurality of dental aligners specific to the user and being configured to reposition one or more teeth of the user.

A syringe housing has a space that is sized for accommodating a syringe containing a fluid to be dispensed. The syringe is insertable into the syringe housing through an opening at a first end of the syringe housing, and a nozzle configured to engage a dispensing tip of the syringe is located at a second end of the syringe housing opposite to the first end. A syringe adaptor, which includes a pneumatic connector that is connectable to a gas supply for introducing a gas into an air chamber enclosed within the syringe housing and the syringe, is removably coupled to the syringe housing for retaining the syringe after it has been inserted into the syringe housing. The gas is operative in use to apply a force inside the syringe to drive dispensation of the fluid through the nozzle.
