The present invention relates to a method for producing a positioning tray for brackets of dental braces, wherein the positioning tray has a positioning aid and one or more associated brackets, wherein the positioning aid is formed as one piece with the associated bracket(s), comprising the following steps: obtaining original data which describe the present geometry of one or more teeth of at least one jaw of a patient; obtaining target data which describe the geometry of the one or more teeth of the at least one jaw of the patient after treatment with dental braces; calculating tray configuration data which describe the geometry of brackets with respect to the present geometry of the one or more teeth of the at least one jaw of the patient and the positioning aid arising from the original data and the target data, wherein the calculation of the tray configuration data is carried out such that using the described brackets of this type, the positioning aid is connected such that it can be used in order to position the brackets with respect to the teeth of the patient such that the bracket(s) can be connected to the surface of the teeth of the patient, and that, together with an ideal curve (basis for planning), previously determined and to be connected to (one of) the bracket(s), a correction of a malocclusion can be carried out; producing, on the basis of the tray configuration data, a corresponding positioning tray through a generative or ablative manufacturing method. The invention further relates to a corresponding device, a computer-readable storage medium and a corresponding positioning tray.

The orthodontic bracket includes a base and a bracket body extending from the base. The bracket body includes a lower labial surface on which a first indicia is displayed and a plurality of tie-wings extending from corner portions of the base on which a second indicia is displayed. The labial surfaces face the patients lips, once positioned on the patient's tooth. The first indicia can be a number corresponding to a specific tooth in a patient's mouth to which the bracket is designed to attach. The second indicia can be a dot positioned on a tie-wing associated with a specific quadrant of the patient's mouth.

A dental template for positioning an object on teeth of a patient and method for fabricating the same. The method includes creating a digital model of the patient's teeth, creating a simplified template model based on the digital model, and fabricating the dental template based on the simplified template model. The template model is simplified by removing certain features of the patient's tooth anatomy. The dental template can be located on a patient's teeth using four or fewer positioning 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.

An automated procedure for correcting teeth misalignment in orthodontics using the steps of Generating a 3D digital model of a jaw having the misaligned teeth. Processing the 3D model to generate a corrective plan. Designing a set of corrective elements capable of applying corrective forces to the misaligned teeth through elastic forces. Designing a set of attachments that react to the corrective forces. identifying locations for applying the attachments to the surfaces of the teeth; Bonding the attachments to the identified locations. Rescanning the jaw of the patient and generating a final 3D model of the jaw with aligned teeth. Fabricating the corrective element in accordance with geometry of the final 3D model of the jaw. Applying the corrective element to the teeth wherein. Removing the attachments. A second 3D scan can be made to determine errors, and finite element analysis may be used to determine force vectors.

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.

The present disclosure provides methods, computing device readable medium, devices, and systems having a dental attachment placement structure. One dental attachment placement apparatus includes a body having an attachment placement surface that is to be placed on an attachment affixing surface of a tooth and wherein the attachment placement surface includes a portion that is shaped to allow placement of an attachment at a particular position on the affixing surface of the tooth and a portion of the body having a contour that is shaped to correspond with a contour of an alignment surface of a tooth and when the contour of the body and the corresponding contour is aligned, the attachment is located at the particular position and can be secured to the affixing surface of the tooth.

An orthodontic appliance and associated systems and methods are disclosed herein. In some embodiments, the appliance comprises an anchor configured to be positioned adjacent a patient's teeth, and an arm extending away from and coupled to the anchor. The arm can include a first end portion at the anchor and a second end portion configured to be coupled to a securing member adhered to a tooth of the patient. The second end portion can include a first region and a second region extending from the first region at an angle. When the appliance is positioned adjacent the patient's teeth and secured to the securing member, the first and second regions may inhibit the second end portion from translating and/or rotating relative to the securing member.

Systems, methods, and devices for producing orthodontic appliances are provided. In one aspect, an orthodontic appliance comprises an outer shell comprising a plurality of cavities shaped to receive the patient's teeth and generate one or more of a force or a torque in response to the appliance being worn on the patient's teeth. The orthodontic appliance can comprise an inner structure having a stiffness different than a stiffness of the outer shell. The inner structure can be positioned on an inner surface of the outer shell in order to distribute the one or more of a force or a torque to at least one tooth received within the plurality of cavities.

Orthodontic braces comprising rotatable versatile brackets are provided. Each rotatable bracket has two different slot sizes, and rotation of the whole bracket before its bonding to the tooth brings one or the other of the slot sizes into horizontal alignment so that different archwires corresponding to the selected size can be accommodated.
