Orthodontic bracket

An orthodontic bracket comprising:

• a body configured to be adhered to a tooth;
• a cover coupled to the body such that the cover is capable of linear and rotational movement;
• and
• an elastic member configured to press the cover to maintain a locked state of the cover,
• wherein the body comprises a wire slot, an attachment surface configured to be adhered to the tooth, a guide part and a body locking part, the guide part having a guide recess formed with an inclination angle, the body locking part being configured to latch onto the cover,
• the cover comprises a hinge part and a cover locking part, the hinge part having a hinge protrusion configured to be inserted into the guide recess to enable linear and rotational movement, the cover locking part being configured to be latched onto the body locking part,
• an upper end of the guide recess is open to receive the hinge protrusion of the hinge part for installation and a lower end of the guide recess is completely closed to limit a downward linear movement of the hinge part of the cover such that the cover remains engaged from the guide recess even when the cover locking part is not properly latched onto the body locking part,
• a distance between the upper end and the body locking part is less than a distance between the lower end and the body locking part,
• a distance between the upper end and the attachment surface of the body is greater than a distance between the lower end and the attachment surface, and
• after the hinge part of the cover is installed in the guide recess, the hinge part of the cover linearly moves along the guide recess when the cover moves from an open position to a locked position.
