ABSTRACT:
The present invention relates to the bracket of an orthodontic appliance for the treatment of dental malocclusion. Brackets of the present invention, which are used for securing the orthodontic wire, are all bonded to the internal sides of teeth, that is, the lingual or palatal side. The wire fixing slot of these brackets is formed either approximately parallel to the tooth axis so that the orthodontic wire may be inserted from the direction of the occlusal plane, or formed almost at a right angle to the tooth axis so that the wire may be inserted from the lingual or palatal side. The bracket has another groove for inserting a lock pin which can lock the fixed wire securely, so that the wire may be locked simply. The bracket is also provided with a shearing groove for cutting the lock pin when the wire is to be exchanged or removed, in order to facilitate the shearing operation with nippers, etc.
