20100129765ORTHODONTIC APPARATUS AND ORTHODONTIC MEMBER - An orthodontic apparatus includes an orthodontic bracket and an orthodontic member removably coupled thereto. The orthodontic member includes an engaging member configured to engage a tie wing of the bracket in non-contact relation with the archwire such that the member exerts no active forces on the archwire. A bumper extends from the engaging member so as to cover a side of the bracket and thereby prevent or reduce contact between the bracket and opposing teeth. The orthodontic member may include a support pad and/or nubs for limiting movement of the member relative to the bracket. The orthodontic member may also include decorative elements for aesthetic purposes.05-27-2010
20100129764CERAMIC ORTHODONTIC BRACKET WITH IMPROVED DEBONDING CHARACTERISTICS - A ceramic bracket has mesial and distal sections that are initially spaced apart from each other by an elongated channel. The bracket is debonded from a patient's tooth at the conclusion of treatment by pivoting one or both of the mesial and distal sections in an arc about a reference axis extending in a direction generally parallel to the channel. The bracket includes a recess that extends across a base of the bracket in generally parallel relationship to the channel. The base of the bracket has an aspect ratio that is less than about 0.95 and enables the bracket to be debonded with less force than might otherwise be necessary.05-27-2010
20110151390Orthodontic bracket - An orthodontic bracket is provided for correcting teeth alignment. The orthodontic bracket allows for not relying on how an operator is skilled in ligation and also for minimizing the friction. The orthodontic bracket includes a slot having an opening into which an orthodontic wire can be inserted, and a shutter that can slide to block or unblock the opening. The orthodontic wire is placed in the slot by causing the shutter to slide and unblock the opening, inserting the wire through the opening, and causing the shutter to slide and block the opening. The orthodontic wire will not disengage from the slot, whereby rotation control, tipping control, and torque control may be reliably performed. Further, it is not necessary to perform ligation that causes the wire to be securely pressed against the bottom of the slot. Since the ligation is not tight, the tooth in question can be smoothly shifted.06-23-2011
20080248440Orthodontic Bracket - An orthodontic bracket includes a base, an archwire slot extending through the base, and archwire slot extensions extending substantially in the mesiodistal direction from opposite sides of the base.10-09-2008

According to one embodiment, the self-ligating orthodontic bracket includes a mounting base for attachment to a tooth surface, an archwire slot formed upon the base and sized for receiving an orthodontic archwire, a rotary ligating cover selectively rotatable between an open position permitting access to the archwire slot and a closed position covering the archwire slot, and one or more locking features for holding the rotary ligating cover in a closed position. In one embodiment, the bracket includes one or more locking tabs on the rotary ligating cover aligned in coplanar relation to the rotary ligating cover and cooperatively mating with cutout portions in the base. In one embodiment, the bracket includes at least one resilient retention mechanism adjacent to the one or more locking tabs and aligned in coplanar relation to the rotary ligating cover. The resilient retention mechanism may include one or more relief channels permitting flexing of at least portions of the rotary ligating cover adjacent to the one or more locking tabs.06-25-2009

The means for selectively narrowing the width of the arch wire slot may comprise one or more spaced apart cuts disposed in at least one side wall defining the arch wire slot so as to define a bendable portion of the sidewall.05-28-2009
20130115567Orthodontic Appliance For Bite Correction - A bite-correcting orthodontic appliance attaches directly to the elements of braces (i.e., brackets and archwires); flexes in its distal 25-45% to stay away from the food bolus; has a reduced elliptical profile for patient comfort; and introduces gentle force vectors to the patient's upper and lower teeth that sweep in an arch to lift up on the front of the molar and down on the lower front teeth as the appliance tries to return to its preinstalled (passive) state, resulting in rapid, yet gentle changes unseen in the orthodontic industry.05-09-2013
20090117512Orthodontic Instrument For Use With Adjustable Orthodontic Apparatus - An instrument is provided, comprising a handle and at least one working end. In a first embodiment, the working end comprised a first leg and a second leg, the second leg for disengaging a spring clip. In a second embodiment, the working end comprises a first leg and a second leg for grasping a connector plate of an orthodontic bracket, and a depth limiter attached to the first leg for preventing inadvertent grasping of an orthodontic bracket base plate.05-07-2009
20130183632UNIVERSAL LINGUAL BRACKET SYSTEM - The present invention discloses a universal lingual bracket system, comprising No. 1-7 universal lingual brackets connected in series by an arch wire. The universal lingual bracket includes a base plate and a bracket body portion that are integrated as a whole. A mesh bottom is arranged on the base plate and the mesh bottom is integrally molded with the base plate. The mesh bottom, the base plate and the bracket body portion are integrally molded. In addition, the mesh bottom is in the structure of an interlaced woven wire mesh, so that the universal lingual brackets have strong capability to be against the teeth surfaces and they are unlikely to come off. Even if they come off, they will not damage the mesh bottom. The mesh bottom can be used again once it is treated by sandblasting. The universal lingual bracket system provided by the invention has the advantages that it can be securely and easily installed and has high durability; therefore it is applicable to various universal lingual appliances.07-18-2013
20110311934Orthodontic Bracket and Arrangement for Correcting Irregularities of the Teeth - An orthodontic bracket comprises a body portion and a locking portion. In the orthodontic bracket there is a surface against the tooth and a surface facing away from the tooth. In the body portion there is an archwire slot for the archwire. There is a locking portion slot in the body portion, which slot is open towards the surface of the orthodontic bracket facing away from the tooth, whereupon it forms an opening on said surface, and the archwire slot is situated in the wall of the locking portion slot. The locking portion can be attached to the body portion. There is a setting slot in the locking portion. The locking portion can be rotated into at least two of the following positions: standby position, in which the setting slot is towards the opening on the surface facing away from the tooth, transfer position, in which the setting slot is towards the archwire slot or locking position, in which the locking portion closes the archwire slot at least partially. The archwire can be placed in the setting slot of the locking portion when the locking portion is in standby position, and the archwire can be placed in the archwire slot when the locking portion is in transfer position, and in the locking position the locking portion is arranged to hold the archwire in place in the archwire slot. The archwire or archwires set in place are in locking position arranged to focus force to the orthodontic brackets. The amount and orientation of the force depend on the stress of the archwire and the orientation of the archwire slot.12-22-2011
20130189638SELF-LIGATING ORTHODONTIC BRACKET - An orthodontic bracket having a bracket body configured to be mounted to a tooth includes an archwire slot having a base surface defining a base plane and a slide engagement track defining a translation plane. The translation plane is angled with respect to the base plane. A ligating slide is engaged with the slide engagement track of the bracket body and movable along the slide engagement track and parallel to the translation plane between an opened position, in which an archwire is insertable into the archwire slot, and a closed position, in which the archwire is retained within the archwire slot. The translation plane is angled with respect to the base plane so as to prevent the ligating slide from contacting the gingiva surrounding the tooth when the ligating slide is moved to the opened position.07-25-2013
20120028206SELF LIGATING BRACKET SYSTEM - A self ligating orthodontic bracket system includes a bracket, a slidable ligating member and at least one wedge locking ramp.
