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.

A method for making an orthodontic appliance comprising: receiving, by a processor of a computer system, a three-dimensional digital model of an orthodontic appliance; determining, by the processor, a compensation factor to be applied when manufacturing the orthodontic appliance using the laser-based system, the determining the compensation factor including: aligning the three-dimensional digital model of the orthodontic appliance in a three-dimensional space with a predetermined position; determining a deviation of a position of a model groove base from a desired position of the model groove base, the compensation factor being based on the deviation and relating to an amount of material to be used during the manufacturing of the orthodontic appliance; causing the laser-based system to apply the compensation factor for manufacturing the orthodontic appliance.

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 for making an orthodontic bracket comprising: receiving, by a processor of a computer system, a three-dimensional digital model of an orthodontic bracket; determining, by the processor, a compensation factor to be applied when manufacturing the orthodontic bracket using the laser-based system, the determining the compensation factor including: aligning the three-dimensional digital model of the orthodontic bracket in a three-dimensional space with a predetermined position; determining a deviation of a position of a model groove base from a desired position of the model groove base, the compensation factor being based on the deviation and relating to an amount of material to be used during the manufacturing of the orthodontic bracket; causing the laser-based system to apply the compensation factor for manufacturing the orthodontic bracket.

A bracket, for an orthodontic device, the bracket including a bracket base including an attachment surface configured to attach the bracket at an associated surface of a tooth; at least one bracket slot configured to receive at least one arch wire of the orthodontic device, wherein the bracket slot is arranged on a side of the bracket base that is oriented away from the attachment surface; and at least one locking device that is configured to lock at least the bracket slot at least partially so that the arch wire is prevented from moving out of the bracket slot, wherein the bracket is integrally formed in one piece, wherein the bracket is configured with a convex camber at a back side that is oriented away from the attachment surface, wherein the convex camber extends over at least 50% of a height of the bracket that is measured parallel to the vertical axis of the bracket.

A device for correcting misaligned teeth, the device including an arc element; and at least two transmission elements, wherein each of the at least two transmission elements is configured to cooperate with a respective tooth surface and includes a respective coupling portion wherein each of the at least two transmission elements is connected or connectable in the respective coupling portion with the respective arc element in a force transmitting manner, wherein the arc element has an overall parabolic cambered shape that is adapted to a lower jaw or an upper jaw of a patient, wherein the arc element includes at least one activation section which is arranged between two adjacent transmission elements of the at least two transmission elements and configured so that the arc element is at least locally elastically deformed in an installed condition of the device.

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.

An orthodontic appliance, includes a crimpable tubular shaped portion having at least three walls selected from the group consisting of a lingual wall, a buccal or labial wall, an occlusal wall and a gingival wall, the at least three walls defining and opening configured to receive an archwire therethrough in a mesial-distal direction. The appliance includes at least one wing joined to the tubular shaped portion, the at least one wing extending longitudinally in the mesial-distal direction. A slot is provided in the at least one wing open to an end of the wing in the mesial or distal direction and having a depth in the mesial distal direction and a height in a gingival-occlusal direction configured to receive a ligature wire or elastic.

A method of fabricating a customized orthodontic appliance includes a setup model forming step of preparing a setup model corresponding to teeth after ideal orthodontic treatment for a patient, an arch wire forming step of preparing an arch wire corresponding to a dental arch of the setup model while being disposed to closely approach tooth surfaces of teeth of the setup model, and an orthodontic bracket forming step of forming a bracket body corresponding to each of the teeth with reference to the arch wire. Through this, the customized orthodontic appliance capable of minimizing the distance between the tooth surface and the arch wire to accurately perform the ideal orthodontic treatment is fabricated. Also, convenience and accuracy of procedure is improved, and irritating sensation in the oral cavity is minimized.

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.
