Abstract
An orthodontic bracket is provided, including a main body, a cover, and an elastic spring element. The main body has an archwire slot configured to receive an archwire. The cover is hingedly connected to the main body, and the cover can be moved between an open position and a closed position. The open position exposes the archwire slot and the closed position covers the archwire slot. The elastic spring element is disposed in the main body, coupled to the cover and the main body, and configured to generate a force that moves the cover into the open position.
Claims16
An orthodontic bracket, comprising:
- a main body, having an archwire slot configured to receive an archwire;
- a cover, hingedly connected to the main body, and the cover is movable between an open position for exposing the archwire slot and a closed position for covering the archwire slot;
- and
- an elastic spring element, disposed in the main body and coupled to the cover and the main body, configured to generate a force to drive movement of the cover into the open position,
- wherein the archwire slot includes a base wall at an end of the archwire slot, a pair of side walls connected to the base wall, and a curved redirecting wall connected to and inclined to one of the pair of side walls, wherein the curved redirecting wall is closer to the cover than the connected side wall, and a surface of the curved redirecting wall facing the other one of the pair of side walls is concave, wherein the pair of side walls is configured to guide the archwire to move in a first exit direction, and the curved redirecting wall is configured to guide the archwire to move from the first exit direction to a second exit direction, wherein the first exit direction is not parallel to the second exit direction.

An orthodontic bracket, comprising:
- a main body, having an archwire slot configured to receive an archwire;
- and
- a cover, hingedly connected to the main body, wherein the cover has a hinge pin confined within a hole of the main body, and the hole is configured to allow translational movement of the hinge pin along a movement direction and allow rotation of the hinge pin about a pin axis of the hinge pin;
- wherein the archwire slot has:
- a base wall at an end of the archwire slot;
- a pair of side walls, connected to the base wall and extending in a first exit direction, wherein the pair of side walls is configured to guide the archwire to move in the first exit direction;
- and
- a curved redirecting wall, connected to one of the pair of side walls and inclined to the first exit direction, wherein the curved redirecting wall is closer to the cover than the connected side wall, and a surface of the curved redirecting wall facing the other one of the pair of side walls is concave, wherein the curved redirecting wall is configured to guide the archwire to move from the first exit direction to a second exit direction, the first exit direction is not parallel to the second exit direction, so that the cover will not move in the first exit direction due to the movement of the archwire within the archwire slot.
