ORTHODONTIC BRACKET HAVING A LINGUALLY BIASED CLOSURE MEMBER AND ASSOCIATED METHOD

摘要

An orthodontic bracket includes a bracket body having an archwire slot configured to receive the archwire and a base surface that at least in part defines the archwire slot. A movable member is engaged with the bracket body and movable between an opened position and a closed position. A resilient member is configured to engage the movable member to impose a force that biases the movable member toward the base surface of the archwire slot. A method of moving a tooth includes inserting the archwire into the archwire slot, closing the movable member to capture the archwire within the archwire slot, and imposing a force on the movable member that biases the movable member toward the base surface of the archwire slot.

主权项

1. An orthodontic bracket for coupling an archwire with a tooth, comprising:
a bracket body that includes an archwire slot defined by a base surface with opposed slot surfaces extending away from the base surface, the archwire having an opening opposite the base surface; a ligating slide engaged with the bracket body and slidable relative to the bracket body between a closed position and an opened position in which the archwire is insertable into the archwire slot through the opening and in a direction generally perpendicular to the base surface; and a biasing member coupled to the bracket body that engages the ligating slide when the ligating slide is in each of the opened position and the closed position.
