Abstract
Systems and methods for moving a tooth using a light, continuous force are disclosed. In examples, a bracket has a surface which is mounted to a tooth, and a pair of wings defining a slot having oppositely disposed upper and lower surfaces that converge at an apex. A wire runs through the slot at a distance from the apex. And a tensioning device presses the wire against a surface of the slot, the system is configured so that the wire gradually moves toward the apex of the slot.
Claims16
A system for moving a first tooth in a patient's mouth, the system comprising:
- a bracket having a surface configured to be mounted to a first tooth and a pair of wings defining a slot having oppositely disposed first and second surfaces that converge at an apex, a wire running through the slot at a distance from the apex, and
- a tensioning device comprising a cap operatively attached to one or more springs, the cap configured to provide a force against the wire and through the bracket pressing the first surface of the slot toward the wire;
- wherein the system is configured so that the tensioning device gradually moves the apex of the slot toward the wire.
A method for moving a first tooth in a patient's mouth, the method comprising:
- mounting a bracket to the first tooth, the bracket comprising a slot having oppositely disposed first and second surfaces that converge at an apex;
- placing a wire within the slot;
- and
- bringing a tensioning device into contact with the wire so as to provide a force through the tensioning device and the bracket, the force through the bracket pressing the first surface of the slot toward the wire at a distance from the apex, thereby imparting a force on the first tooth;
- wherein the tensioning device is a cap-style clip that gradually moves the bracket such that the apex of the slot moves toward the wire.
