Systems, methods, and devices for producing appliances for expansion of the arch of a patient are provided. An arch expanding appliance comprises a force generating portion to apply an arch expansion force and a retention portion to hold the force generating portion on the teeth. The retention portion comprises a flexible portion and a stiff portion. The force generating portion applies a force to move teeth associated with the flexible portion, while the stiff portion resists movement of its associated teeth. The orthodontic appliances can be designed according to the specifications provided herein and manufactured using direct fabrication methods.

A dental appliance having an integrally formed reservoir and/or an ornamental design integrated thereon. The ornamental design can be selected or customized by a patient. The design can be created by directing energy to the dental appliance to alter a material property of at least a portion of the appliance to create the design. Alternatively, a groove or recess can be formed on a surface of the appliance to either mechanically retain an ornamental design or the groove or recess can be filled with ink to form the design. The appliance, including the integrally formed reservoir, can be formed using direct fabrication techniques.

The present disclosure relates to ornamental indicia carrier and method of producing the same. In some embodiments, the ornamental indicia carrier comprises an ultraviolet light (“UV”) cured ink printed on a thin flexible film and combined with an adhesive layer. The ornamental indicia carrier is capable of enduring the conditions inside the mouth for an extended period of time and can be used in conjunction with a dental appliance.

A cover device formed of a plastic or similar composition is structured for removable attachment over a bracket of an orthodontic appliance to conceal the bracket from view. The cover device includes a main plate with an outer front face, and top and bottom claws integrally formed with the main plate, curling behind the main plate, and each terminating at distal ends in spaced, opposing relation to each other behind the main plate. The front face includes an ornamental design or other indicia that is applied by polymer fusion technology to significantly reduce the risk of exposing the user to inks and pigment compositions, particularly if the cover device is accidentally swallowed. The application of the indicia by polymer fusion technology also increases the structural integrity of the cover device; mechanically strengthening the cover device at its point of greatest flexure.

A dental bracket has a base and an engaging unit. The base has two engaged protrusions and two limiting protrusions. The engaging unit is mounted on the base and forms a space between the base and the engaging unit. The engaging unit has a plate, two engaging arms, and a blocking protrusion. The plate has a first surface and a second surface being flat and opposite the first surface. The two engaging arms are formed on the first surface of the plate and respectively engaged with the two engaged protrusions of the base. The blocking protrusion is formed on the first surface of the plate, is arranged between the two limiting protrusions of the base, and divides the space into two channels for inserting an archwire. The second surface of the engaging unit is flat and is able to decrease the foreign body sensation in the mouth.

The invention provides an intelligent dental ornament and a method of using the same, the intelligent dental ornament comprising: a dental ornament body with a cavity, a tester located within the cavity and for detecting a physiological parameter, a battery used by the tester, and a trigger switch for triggering the tester to start test; the dental ornament body is further provided with a through-hole for at least one pipette of the tester stretching out of the dental ornament body, and a sealing cover for sealing the through-hole. When the trigger switch activates the tester, the sealing cover is opened, and the pipette of the tester stretches out of the dental ornament body through the through-hole to obtain the saliva of the subject, and the physiology parameter in the saliva is detected, and the detection result is sent to an external device in communication with the tester. The intelligent dental ornament can intelligently detect the physiology parameters such as the blood glucose or alcohol content without affecting the aesthetics of the dental ornament, and has the advantages of simple operation, reducing pain of the user, being reusable, and reducing cost.

The removable veneer for teeth is a cosmetic accessory adapted to overlay the teeth. The accessory includes a veneer designed to simulate perfectly positioned human teeth. A fastener system is employed to removably attach the veneer to the existing natural teeth of a user. Various teeth adornments may be attached to the veneer, if desired, when the wearer wants to assume a more modern look.

Systems, methods, and devices for producing appliances for expansion of the palate of a patient are provided. A palate expanding orthodontic appliance comprises a teeth engagement portion comprising a plurality of teeth engagement structures and a force generating portion coupled to the teeth engagement portion and configured to apply force to cause the patient's palate to expand. The orthodontic appliances can be designed according to the specifications provided herein and manufactured using direct fabrication methods.
