Abstract: The present invention is directed to orthodontic brackets having wire slots therein that are less than about 0.0175 inches in width, and greater than about 0.0165 inches, and more preferably about 0.017 inches. Additionally, the slots of the brackets of the invention can have a shallower depth than prior art slots, and in particular, a depth of approximately 0.024 inches. Thus, in one embodiment, a bracket having a slot of 0.017?×0.024? (0.43 mm×0.60 mm) is provided, wherein this new bracket is particularly useful for reorienting second molars. Moreover, the brackets of the present invention are in keeping with clinical requirements for anchorage and the need for overtreatment. In addition, the present invention meets the needs for placing teeth in positions to protect against the forces that cause malocclusion in order to best prevent relapse. Furthermore, the present invention provides the requirements for application of appropriate forces, particularly dental expansion.
