摘要:
An orthodontic bracket is disclosed having three archwire retention channels in the mesial-distal directions, a central channel and two side channels. The two side channels each include a pair of spaced apart inverted archwire retaining regions having a recess that opens generally towards the bracket base. Each such recess is for grasping or holding an archwire therein. Other aspects are directed to a self ligating orthodontic bracket system that includes a rotatable member for securing an archwire within a slot of a bracket; embodiments that include an orthodontic appliance and method of producing and using the same, and preferably employed in a lingual orthodontic system, that includes friction reducing features between an interior of an archwire slot portion of the appliance and an archwire placed within the archwire slot.

Orthodontic bracket assemblies with torque-adjusting drums. The drum defines at least a majority of the archwire slot of the corresponding bracket assembly, and the drum may be selectively rotated about its longitudinal axis to adjust the prescriptive force that is applied to a patient's tooth during orthodontic use of the bracket assembly. The bracket assembly includes a positioning assembly that selectively retains the drum in a selected orientation relative to the base of the bracket assembly, thereby defining a prescription to be imparted by the bracket assembly to a patient's tooth. In some embodiments, the bracket assembly includes a biasing mechanism that selectively urges the positioning assembly to a position in which the drum is, or is not, retained in a selected position. In some embodiments, the bracket includes a release mechanism that selectively disengages the positioning assembly to permit adjustment of the drum.

An orthodontic bracket includes a bracket body and a ligating slide. The bracket body includes an aperture and an archwire slot. The ligating slide is slidable relative to the archwire slot between an opened position and a first closed position and is pivotable to an angular position in a second closed position. The orthodontic bracket further includes a resilient member that is coupled to the ligating slide and is slidable in the aperture. The ligating slide defines a first height from the base surface having a first value, and in the second closed position, the ligating slide defines a second height from the base surface that is greater than the first value. The bracket body includes a slide support portion having at least one wing extending laterally therefrom. The wing is tapered in thickness. The slide support portion defines a pivot point about which the ligating slide is pivotable.
摘要:
An assembly of a self-ligating bracket intended to be part of an orthodontic apparatus. The bracket having in the longitudinal direction thereof an outer face and an occlusal face and being provided on the outer face thereof with a groove for holding an orthodontic arch wire. An elastic clip that can be moved in a reversible manner between an open position, leaving a free passage for the insertion of the arch wire into the groove or the extraction of the arch wire from the groove, and a closed position closing off the groove. The clip being moveable between said positions by a rotational movement, without the clip sliding in translation.

A self-ligating attachment intended to form part of an orthodontic appliance, the external surface of said attachment being provided with a groove for receiving an orthodontic arch. A elastic clip that can be reversibly moved between an open position forming an open passage allowing the insertion of the arch into the groove and a closed position sealing the groove. A base including an external surface that supports the attachment and an occlusal surface which is intended to rest on one of the patient's teeth, so as to hug the surface of the tooth. In addition, the base comprises a support for the attachment and said base assists in the guiding of the clip, cooperating with the attachment, as the clip moves between the open and closed positions.

The orthodontic archwire bracket comprises a base body (10) having a base element (11) to be fixed to a tooth and a bracket body (20) having a socket element (25) surrounded by a perimetric wall (32) including two opposed slot portions (21a, 21b) forming a slot (21) to receive an archwire. The base and bracket bodies (10, 20) are connected by a ball and socket joint coupling. The perimetric wall (32) has a slit (33) providing a gap. A control element (60) mounted on the bracket body (20) is changeable between locking and unlocking positions to expand or constrict the bracket body (20) by increasing or reducing the gap. The ball and socket joint coupling is locked by friction when the control element (50) is in the locking position and the ball and socket joint coupling is unlocked enabling relative movement in three coordinate axes when the control element (50) is in the unlocking position.
摘要:
A self-ligating orthodontic bracket for ligating an archwire includes a bracket body defining an archwire slot configured to receive the archwire, a movable member movable relative to the archwire slot, and an actuator coupled to at least one of the bracket body and the movable member. The actuator includes a ferromagnetic shape memory alloy and is configured to move the movable member when exposed to a magnetic field. A method of orthodontic treatment using a self-ligating orthodontic bracket having an archwire slot configured to receive an archwire therein and including a ferromagnetic shape memory includes exposing at least a portion of the orthodontic bracket to a magnetic field such that the ferromagnetic shape memory alloy at least partially transforms to a martensitic phase from an austenitic phase, and at least one of inserting an archwire into the archwire slot and removing an archwire from the archwire slot.

Orthodontic anchoring method and custom appliances affixed to teeth, TADs and/or tooth positioning, moving and stabilization appliances and/or orthodontic auxiliaries. Each appliance has mechanical fasteners structured to secure segments of a curable flexible resin rope called a flex fit module (FFM). The FFM is moldable and adaptable to the oral cavity between mechanical fasteners in an uncured first mode where it is cut to length, positioned around the anatomy of the mouth and attached to clamps or fasteners and/or flex fit wafers FFW(s) at each or one end. Each fastener has a clamp or fastener attached to orthodontic auxiliaries, orthodontic appliances or onto a TAD for anchorage purposes. One end of this custom appliance is usually attached via a clamp or fastener manufactured as part of a bracket or band to a tooth. The other end is connected to an appliance, tad, flex fit wafer or auxiliary. Once connected together the system is cured and becomes a solid entity ready to accept orthodontic forces.
