The present invention relates to an orthodontic gripping device having a body made of a superelastic metal alloy, cold worked titanium beta III, or solution heat treated and aged titanium beta III. The body has first and second, spaced apart arm portions connected to each other. Each arm portion includes a jaw portion having an inner, arch wire-gripping, surface. The inner gripping surfaces are disposed opposite one another in spaced relation with a station defined therebetween for receiving the arch wire. At least a portion of the station is sized smaller than the arch wire. The arm portions are resiliently deflectable outwardly away from each other to admit the arch wire into the station. Once seated in the station, the arch wire is tightly held by inner gripping surfaces so as to resist displacement of the gripping device relative to the arch wire.

An orthodontic device (10) comprising, a first opening (11) for receiving a first anchoring structure, a second opening (12) for receiving a second anchoring structure and a third opening (13, 14, 15) for receiving a third anchoring structure, the first, second, and third anchoring structures being attached in a mouth of a subject, and an intermediate structure (18) connecting the first, second and third openings, wherein one or more of the openings are stretchable, and wherein the intermediate structure and the openings are made from a creep resistant material.

Non-sliding orthodontic appliances may include an archwire having male fasteners for locking in place with brackets in a non-sliding manner and interproximal loops for exerting forces on the brackets. Appropriate forces may be calculated according to vectors between initial and ideal tooth positions. The brackets may be transferred to a patient's teeth using indirect bonding trays which contain slots for holding and aligning each bracket. The trays may include integrated handles for facilitating handling, may be sectioned into smaller pieces for easier application, and/or may be labeled for facilitating proper registration. Superposition of a digital placement plan and clinical model after bonding may illustrate the accuracy of bracket placement. The archwire may comprise atraumatic ends to avoid patient discomfort. A color registration system can be used to facilitate the attachment of the archwire to the brackets. The archwire may be locked into place with the brackets using crimpable stops.

An orthodontic post and pin system for secure attachment of a dental appliance to an alignment wire, which also facilitates quick and easy removal and replacement. The system described herein uses a “twist-lock” dental post that is rotated onto, and counter-rotated off of, an alignment wire. The dental post includes structural elements to facilitate the twist-lock functionality, as well as structures for accepting a fastener to secure the alignment wire in place and inhibit unintentional or undesired dislodging.

Orthodontic bracket assemblies with archwire cradles that pivot in correspondence with the rotation of pivot-adjusting drums. The orthodontic bracket assemblies include a pivot-adjusting drum that is configured to be selectively rotated relative to a bracket base about an adjustment axis within a range of operative rotation positions, an archwire cradle that is configured to be selectively pivoted about a cradle axis relative to the bracket base within a range of operative pivot positions, and an adjustment driver that is operatively coupled to the archwire cradle and the pivot-adjusting drum and causes the archwire cradle to pivot relative to the bracket base in correspondence with a rotation of the pivot-adjusting drum. A rotation of the pivot-adjusting drum about the adjustment axis adjusts the torque that is applied to the patient's tooth during prescriptive use of the bracket assembly.

The disclosure relates to an orthodontic system and treatment method, including an arrangement of orthodontic brackets against the patient's teeth such that the depth of the respective archwire slots of the brackets generally increases from the anterior teeth moving toward the posterior teeth. The gradual increase of the archwire slot in the bracket arrangement provides for finer control over the movement of the anterior teeth, while providing sufficient control and freedom of movement for the posterior teeth.

An orthodontic correction device includes a correction unit that is adapted to be removably worn on a dental arch. The correction unit includes at least one first receiving part for receiving at least one first tooth which needs correction. The shape of the first receiving part allows the first tooth to move toward the alveolar bone. At least one elongated opening is formed on the occlusal surface of the correction unit and extends to the lingual surface and the buccal surface of the correction unit. The opening exposes parts of the occlusal surface, the lingual surface and the buccal surface of the first tooth. A force exerting assembly is configured to contact the first tooth through the opening, thereby exerting a force on the first tooth to press the first tooth into the alveolar bone.
