Abstract:
One aspect of the present invention is a self-ligation type orthodontic bracket which has a simple structure and in which a shutter can be reliably opened and closed, and fixed. The orthodontic bracket is provided with: a bracket body having a slot to which a wire is attached and an introduction port connected to the slot; a shutter provided between the slot and the introduction port to be able to move forward and backward; and a stopper wire which is attached to the bracket body and prevents the shutter from detaching. The stopper wire is elastic. Both end parts of the stopper wire are supported by the bracket body. When the shutter is closed, the central part of the stopper wire is located at a position which blocks the path along which the shutter moves forward and backward.
