A detachable orthodontic bracket and wire system includes bracket bases, brackets, and an arch wire for guiding alignment of teeth. The bracket bases are positioned on a lingual surface and/or a facial surface of the teeth. Each bracket base includes a first surface, a second surface, and at least one first interlocking element. The first surface is rigidly attached to the lingual surface and/or the facial surface of the teeth. The second surface opposes the lingual surface and/or the facial surface of the teeth. The first interlocking element is attached to and positioned in a direction substantially perpendicular to or parallel to the second surface of each bracket base. The brackets include at least second interlocking element that interlocks with the first interlocking element. The arch wire is inserted through a slot channel of each bracket. The bracket and the arch wire are infused and rigidly anchored within enclosing layers.

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.

The present disclosure provides methods, devices, and systems that utilize dental appliance etch templates prior to or during dental treatment. One dental appliance etch template includes a removable shell having one or more cavities formed therein, where the one or more cavities are shaped to receive teeth of a patient, and the shell includes a well, the well including a wafer, where the wafer includes etch material to etch a tooth of the patient.

The present invention relates to orthodontic brackets designed for use with the deciduous teeth and method for its use. The brackets provide one or more debonding tabs which reduces the potential for damage to the deciduous tooth due to the application of excessive force during the debonding process. The small size of the brackets allow the brackets to fit available crown space on the deciduous teeth. Further the brackets are shaped to minimize mechanical forces applied to the deciduous teeth when engaged with an archwire. The bracket bases are shaped to conform to the morphology of the deciduous tooth crown surface thereby providing an optimal adhesive interface with the deciduous tooth. The deciduous brackets provide proper adhesion to avoid unwanted detachment of the brackets which often occurs when the use of permanent brackets is attempted on the deciduous teeth.

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.

A method of manufacturing pre-formed, customized, ceramic, labial/lingual orthodontic clear aligner attachments (CCAA) by additive manufacturing (AM) 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 using reverse engineering, and saving the 3D CAD model, designing a 3D CAD structure model for one or more CCAA on various parts of each tooth, importing data related to the 3D CAD CCAA structure model into an AM machine, directly producing the CCAA in the ceramic slurry-based AM machine by layer manufacturing, enabling the provider to deliver patient-specific CCAA's by an indirect bonding method to the patient's teeth to improve the efficacy and retention of the clear aligners.

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.

A training method for evaluating the bonding accuracy of orthodontic brackets is provided. The evaluation method includes a training device for racket bonding accuracy evaluation which includes virtual teeth with root-shaped connectors and an evaluation base to fix the virtual teeth. Multiple reference lines are marked on the evaluation base, and their intersection is set as the evaluation point. When the virtual tooth is fixed to the evaluation base, the reference lines and the evaluation points are utilized for rapid evaluation of the bonding accuracy of the bracket. Moreover, thanks to their horizontal arrangement, when there are multiple virtual teeth, the evaluation of bracket bonding would be more intuitive and efficient than using the traditional articulator.
