Abstract
An orthodontic bracket enables orthodontic treatment to be performed without resetting of a bracket body and an arch wire relative to the tooth, even in an advanced stage of the treatment. The orthodontic bracket comprises a bonding plate having a bonding surface matching the curvature of the tooth, a base having a bottom surface united with the bonding plate and an upper surface serving as a sliding surface parallel to the longitudinal axis of the tooth and taking an approximately rectangular shape in plan with a convex curve formed in accordance with the long axis of the tooth. A bracket body is mounted on the sliding surface of the base so as to be slidable along the tooth axis. The base has, at opposing sides of the sliding surface, grooved parallel rails for slidably holding the bracket body therebetween. Each rail has, at its opposite ends, stoppers to prevent detachment of the bracket body. The sliding surface has a central longitudinally-extending visible median line. The bracket body has, on its upper surface, wire slots arranged approximately orthogonal to the tooth axis.
