An orthodontic bracket is provided, including a backend surface, a frontend surface, a first side surface, a second side surface, and a passageway. The backend surface is adapted for attachment and is opposite the frontend surface. The first and second side surfaces are connected between the backend surface and the frontend surface. The passageway extends from the first side surface to the second side surface. The cross-section of the passageway includes an access opening, an archwire slot, a path portion, and at least one rotation portion. The access opening is configured to allow the archwire to enter the passageway. The archwire slot is configured to receive the archwire. The path portion connects the access opening and the archwire slot. The rotation portion is provided in the path portion to allow the archwire to change its orientation.

The invention relates to an orthodontic bracket system, wherein an orthodontic wire is held in an open channel or slot which receives an orthodontic wire without means of any type of applied ligature or any type of moving cover. Disclosed is a static self-ligating orthodontic bracket system for coupling a pre-tensioned arch wire with a tooth, wherein the bracket comprises a bracket body configured to be mounted to a tooth, an arch wire slot configured for receiving a pre-tensioned arch wire therein, the arch wire slot configured with a at least one protruding stop or protuberance on an interior wall surface thereof, the stops spaced apart from one another, and a slot opening for receiving the arch wire into the arch wire slot, the opening having a width less than a diameter of the arch wire slot, wherein the arch wire is configured with a non-spherical cross-section.

An orthodontic bracket is provided, which comprises an outer body, an elastomeric inner body coupled to the outer body, and a bracket base configured to couple to a tooth. The inner body of the outer body is disposed between the outer body and the bracket base. In an embodiment, a removable dental appliance comprises a plurality of polymeric shell portions each having one or more cavities shaped therein to receive one or more teeth and wherein each of the plurality of shell portions is formed to be separate from the other plurality of shell portions, wherein the bracket base is a polymeric shell portion.

Systems, methods and apparatus are provided through which in some implementations an orthodontic apparatus includes a plurality of brackets, wherein each of the plurality of brackets includes a carbon-nanotube forest upon a carbon-nanotube bonding substrate that is adhered to a lingual bracket bonding surface, forming a plurality of carbon-nanotube bonding substrates.

In an embodiment, a method of manufacturing customized ceramic labial/lingual orthodontic brackets by additive manufacturing may comprise measuring dentition data of a profile of teeth of a patient, based on the dentition data, creating a three-dimensional computer-assisted design (3D CAD) model of the patient's teeth, and saving the 3D CAD model, designing a virtual 3D CAD bracket structure model for a single labial or lingual bracket structure based upon said 3D CAD model, importing data related to the 3D CAD bracket structure model into an additive manufacturing machine, and directly producing the bracket with the additive manufacturing machine by layer manufacturing from an inorganic material including at least one of a ceramic, a polymer-derived ceramic, and a polymer-derived metal.

A computer system and computerized method in which orthodontic treatment, including midcourse correction of one or more teeth in a dental arch fitted with a dental appliance, comprises a virtual simulation of a dental arch fitted with a virtual dental appliance in which each of the one or more teeth can be discretely moved from an initial position to a final position allowing modification of the fitted dental appliance by computerized selection of one or more brackets and production of a bonding tray adapted to hold the selected brackets in correspondence to determined bracket bonding locations in the virtual simulation of dental arch.
