An orthodontic bracket has at least one base configured for attachment to a tooth surface and at least one bracket element arranged at one side of the at least one base, the at least one bracket element comprising—at least one arch wire slot—two wall portions wherein the orthodontic bracket comprises at least one one-piece covering door having at least one first free end which is shaped to fit within at least one indentation of a first wall portion. The at least one indentation comprises at least one locking elevation and the at least one covering door comprises at least one locking deepening. The at least one bracket element and/or the at least one base comprises composite material such as polyurethane material, and/or the at least one covering door comprises composite material such as polyurethane material, and/or comprises ceramic material.

A method for treating orthodontitis (i.e., gingivitis caused by malpositioned teeth). The process includes evaluating improper morphologies of alveolar bone in the horizontal dimension (i.e., orthodontosis) caused by displaced root(s) of a tooth, uprighting the root of the malpositioned tooth utilizing an orthodontic bracket system thereby causing the alveolar bone to be restored, which in-turn alleviates the orthodontitis. An orthodontic bracket is provided for use with an arch wire to apply corrective forces to a tooth. The bracket includes a vertical member having a slot formed therein for receiving the arch wire and a wide base horizontal member connected to the vertical member. The vertical member is positioned gingivally with respect to the horizontal member. The horizontal member includes opposing first and second ends that extend away from the vertical member and define a pair of spaced-apart wire engaging points engageable with the arch wire during treatment.

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.

An orthodontic bracket can include a bracket body. The bracket body can include an outer body. The bracket body can also include an inner body coupled to the outer body. The orthodontic bracket can include 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.

The invention relates to an orthodontic device which is particularly economical and as small as possible, and which has hooks and a small tube, produced from a sheet metal plate using stamping and bending techniques and without the use of welding or soldering. The orthodontic device comprises a base plate having a flat region with a gingival and an occlusal edge. An occlusal rolling forms the small tube. The gingival edge has a counter-directional rolling. Concave cuts are formed in the side edges in order to form wing-shaped hooks. Both rollings can hold an applicator/protector, with which the orthodontic device is protected during adhesion, and can then be applied to a tooth in the correct orientation.

An orthodontic bracket extension system for orthodontic braces, the orthodontic bracket extension system including a plurality of bracket base extensions each having an aperture in which a corresponding one of a plurality of bracket base can be disposed to increase a bracket bonding surface area for greater securement of each of the plurality of brackets to each of a corresponding plurality of teeth.

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 method of aligning teeth and an orthodontic appliance are provided. The orthodontic appliance is configured to be adhered to a surface of a tooth and configured to receive a plurality of differently sized archwires. The orthodontic appliance includes a bonding surface configured to be adhered to the surface of the tooth, an opposing outside surface, a plurality of sidewalls extending between the bonding surface and the opposing outside surface, and an archwire groove extending from a sidewall of the plurality of sidewalls parallelly between the bonding surface and the opposing outside surface.

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.

The invention relates to a bracket for correcting the position of a tooth, comprising a bracket base of a bracket body, which bracket base can be fastened to a tooth, and which bracket body has a slot, extending in the mesiodistal direction, and also a fourth slot portion that narrows by a predetermined amount (α) in a predetermined region, so as preferably to form a snug fit for an inserted archwire, wherein the fourth slot portion is designed running in the longitudinal direction substantially parallel to the bracket base.
