摘要： The present invention relates to an improved orthodontic bracket mountable on a tooth surface for use in orthodontic mechanics to facilitate movement of teeth along an arch defined by the shape of an arch wire. This orthodontic bracket appliance of the invention provides reduced resistance to sliding during orthodontic tooth movement by incorporating rotating members within the arch wire channel or tube to reduce friction.
