arrangement for remedying toothmalpositions

摘要

The bracket contains a slot aligned in such a way that an imaginary slot plane extending along the slot and through the slot base and slot mouth will form a sharp angle relative to the plane of the base plate. The slot mouth facing away from the vertex faces essentially in the direction of the occlusal edge of the base plate. The bracket comprises a base plate for bonding to the lingual side of a tooth (11-15), provided with occlusal and gingival edges on opposite sides. A raised structure above the base plate contains a slot extending essentially parallel to the base plate for receiving a alignment wire. A fixture is provided for holding the wire inside the slot.
