Abstract :
In fixed orthodontic therapy, tooth must be moved during leveling, alignment or retraction into an extraction area. During these procedures, friction is considered between archwires and brackets in sliding mechanics. Friction must be controlled so that the proper force can be applied to obtain tooth movement, to maintain anchorage and to optimize biologic tissue response. The purpose of this article is to review studies which have been carried out to evaluate the factors that influence frictional resistance. These include brackets, orthodontic wires and biologic factors. These factors should be considered for proper tooth movement in orthodontic treatment.
