An orthodontic device and, in particular, an orthodontic bracket that is slidable along a wire without external forces is provided. The device may include a first and second gear, each of which are independently movable between a locked position in which the gear is prevented from rotation, and a released configuration in which the gear extends into the channel to engage a wire received within the channel and is rotatable to move the device along the wire. The first gear may be rotatable to move the device in a first direction while the second gear may be rotatable to move the device in a second direction opposite the first direction. Thus, the first and second gears have the ability to move along the wire in short or long distances, as desired.

A dental device comprising one or more elongate elements such as wires arranged to contact and exert pressure on one or more teeth, and a reel, which reel is arranged to move the elongate element.

A method or apparatus for controlling movement of one or more teeth comprising a device and a software application operated remotely.

An orthodontic correction system is disclosed for correcting Class II malocclusions, Class III malocclusions, dental asymmetries and/or dental related skeletal anomalies in which the patient's dentition is permanent or near permanent. The correction system attaches to a patient's dentition via a novel orthodontic appliance that is affixed to, e.g., pre-installed upper and lower archwires. The correction system includes one or more adjustable length assemblies each of whose ends pivotally attach to a patient's preinstalled maxillary and mandibular archwires. Each pivot is a ball hinge comprising a spherical head that pivotally attaches, allowing the alignment assembly to have free excursion, motion, and/or rotation along multiple axes.

A teeth adjustment arrangement includes a plurality of end retainers adapted for affixing to abutting teeth respectively; and a space expansion unit coupled between the end retainers to create an opposed expansion force against the end retainers for enlarging a corrective space between the abutting teeth corresponding to an associated tooth therebetween. Therefore, the associated tooth is adapted to concurrently move within the corrective space and align with the abutting teeth at the same time.

Embodiments of the present disclosure are directed to devices and a method for orthodontic torquing. For the various embodiments, a pliers for crimping coils of an orthodontic torquing spring to an arch wire includes: a pair of plier halves, each of the plier halves including a handle, a jaw, and a pivot section, each of the jaws including a crimping face defined by a distal edge having a length in a range of 200 percent to 400 percent of a diameter of the orthodontic spring, a first lateral edge, and a second lateral edge, the edges defined by a radius of curvature in a range of 0.1 millimeters to 0.5 millimeters, a textured surface on at least one of the crimping faces to frictionally engage the coil of the orthodontic spring, and a pivot joint connecting the pivot sections of the pair of plier halves such that the handles can be manipulated to cause the crimping faces of the jaws to move together to crimp a coil of the orthodontic torquing spring to the arch wire.

A method and system for optimizing stiffness of an orthodontic archwire for a tooth malocclusion of a patient with a computer system, the method including: constructing a model of a patient's teeth in the computer system; inputting material properties of the archwire to the computer system; and determining an adjusted stiffness of a first section of the orthodontic archwire, the first section associated with the tooth malocclusion of the patient. In some cases, the adjusted stiffness may be determined based on different variables associated with the patient's teeth, which may include at least one of interbracket distance, malocclusion magnitude, bracket slot size, wire size, teeth size or extent of stiffness modification of the archwire.

An orthodontic retention system includes a fixed component that remains on teeth and a component that attaches to this fixed component. The fixed component and the component have mating or interlocking parts. The component that mates with the fixed component can be removable. The component that mates with the fixed component can be adjustable. The retention system also can include magnetic retention components to retain the removable component with respect to one or more teeth. The retention system also can include an element that replaces as tooth.
