A pliers for forming orthodontic wires has opposing beaks with complementary wire-forming surfaces that include interfering portions. A hinge mechanism enables the beaks to open and close by rotating about an axis, and also allows a range of axial motion between the beaks sufficient to prevent interference between the wire-forming surfaces as the beaks are closed. By preventing such interference, novel over-bending capabilities can be achieved to form useful bending of low spring rate wire. A spring, such as a Belleville washer, exerts a biasing force parallel to the hinge axis to maintain alignment of the beaks, but allows the required range of axial motion between the beaks to prevent interference.

The tube bore includes mesial and distal ends and a center portion. The center bore portion has a shape and dimensions for receiving and securing the wire. Both the mesial and distal bore ends of the tube are flared to accommodate receiving the arch wire, particularly when extending an arch wire from a first mesial buccal tube to a second distal buccal tube as adjacent molars are engaged in the orthodontic process.

The present invention aims to provide an orthodontic appliance capable of aligning teeth within a shorter period of time than usual without using braces including an orthodontic wire and brackets. This appliance is provided with a dental mouthpiece mountable on teeth and a vibrating element. The dental mouthpiece is so shaped as to apply a biasing force in an aligning direction to a tooth to be aligned in the teeth while being mounted on the teeth. The vibrating element is attached to the dental mouthpiece, generates mechanical vibration and applies the vibration to the tooth to be aligned, thereby activating the bone remodeling of a target tooth and an alveolar bone to promote an orthodontic effect.

An apparatus for bending orthodontic wires has means for guiding and holding a wire. In order to prevent forces resulting from compressive or stretching strain during the bending process, one of these means does not apply any longitudinal forces onto the wire by design. In another implementation, the apparatus for bending orthodontic wires has a gimbal-mounted gripper for bending the wire. Furthermore, a method is disclosed for applying two bends at the same longitudinal wire location in two different directions.

The present invention provides an orthodontic connector, along with related assemblies, used in coupling an orthodontic wire to an orthodontic auxiliary such a force module. The connector includes a slot with rigid and opposing walls and one or more flexible clips, which independently engage the wire. The combination of rigid and flexible components allows the connector to easily engage to and disengage from the wire and couple with a wide range of auxiliaries and fixed orthodontic appliances while simultaneously preventing the connector and associated auxiliary from unduly rotating about the longitudinal axis of the wire. Restricting this rotation advantageously prevents these components from either rotating into the occlusion or into the patient's soft tissue.

Interactive / passive bracket system developed to provide orthodontic treatment in a more comfortable, efficient and faster manner. Its function with the orthodontic wire may be determined by an orthodontist in order to make it interactive or only passive. It is something innovative because no bracket system can provide these two features in the same bracket. The presence of two convertible slots which is also a significant differential feature will simplify the tooth movement in the class I, II and Angle III relations. Besides, the rounded design makes the Revolution systems more comfortable and traps less food, thus facilitating brushing.

An orthodontic device allows direct attachment to orthodontic wires. A force module central portion is coupled to upper and lower end caps. The end caps have clip members that permit direct clipping onto the orthodontic wires to thereby retain the force module on the orthodontic wires. The clip members comprise first and second spaced apart curved members curving in a first direction and an intermediate curved member curving in the opposite direction. One or more of the curved members may flex to allow passage of the orthodontic wire. Alternatively the curved members have different radii of curvature to form a gap that is slightly smaller than the expected size of the orthodontic wire to permit the orthodontic wire to be forced between the gap and retained within a receiver portion formed by the curved members.
