Abstract
An orthodontic bracket is provided that includes a cover and a base, wherein the cover can be rotated over an arch wire slot in the base portion. The present bracket invention operates to close when a frangible portion is severed upon initiating rotation of the cover, such that the cover rotates about a hinge, which may include a pin or axle. In one embodiment of the invention, the pin or axle can be moved laterally and/or vertically after the frangible portion is severed. Preferably, the bracket is manufactured to form one piece, such as using an injection molding, machining, or casting process. The bracket offers economical advantages because additional subsequent assembly is not required to attach a cover to a base.
