<P>PROBLEM TO BE SOLVED: To improve the aesthetics, use and functionality, and the cost and manufacturability of self-ligating orthodontic brackets. <P>SOLUTION: The orthodontic bracket 10 for coupling an archwire 18 with a tooth includes a bracket body 12 configured to be mounted to the tooth and a clip 14. A clip slot extends through the bracket body transversely to an archwire slot 16. Upon deflection of the clip, it contacts the bracket body at locations that are not in contact before the deflection. The clip includes various structures that cooperate with the body when the clip is deflected to restrict or stop the deflection. The orthodontic bracket may comprise a securing mechanism that is configured to secure the clip in a closed position. A method of manufacturing a shaped unsintered body for use in manufacturing the orthodontic bracket is also provided. A portion of the sinterable particles may be removed using a stream of energy to yield a plurality of posts which are then deformed. <P>COPYRIGHT: (C)2012,JPO&INPIT |
