  • Patent number: 8827698
    Abstract: Provided is an improved self-ligating orthodontic appliance and methods of assembling the same. The improved orthodontic appliance uses at least one resilient clip to releasably couple an archwire to the body, where a portion of the clip is rigidly coupled to the appliance body in a position and orientation that minimizes the overall profile of the appliance. The appliance is assembled by combining a press fit coupling between the clip and appliance body with an interference fit coupling between the clip and retaining structure located on the body. Advantages include a greater freedom to select a bonding pad location, lower bracket profile, decreased engagement force, enhanced clip fatigue life, and ease of assembly.

  • Patent number: 8714973
    Abstract: 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.
