Abstract
An archwire stop defines a non-linear path through the stop that results in a bend moment between an orthodontic stop and the portion of an orthodontic archwire passing through the stop. The bend moment is accommodated by elastic deformation of the archwire and stop, resulting in a predictable frictional engagement between the stop and the archwire that is useful in maintaining a stop mounted on an archwire during packaging, shipping and handling in a clinical setting. A non-linear path through an archwire stop may be created by a non-linear tubular stop or may be created by appropriate internal features of the stop. The non-linear path through the stop may be selected so that the frictional engagement is greatest toward the free ends of the archwire, preventing the stop from sliding off the ends of an archwire, while permitting adjustment of the stop at the front of the mouth during patient treatment.
