Abstract
An at least aesthetically integral orthodontic appliance which is formed from an orthodontic base and a separately formed orthodontic body, as well as a method for making the same. In one embodiment, a base and body are separately formed by metal injection molding, the upper surface of the base having a pair of preferably mesio-distally extending alignment rails formed thereon. The lower portion of the body is positioned between these rails and forced into engagement with the base. The resulting assembly is thereafter heat treated to form an at least aesthetically appearing and preferably structurally integral orthodontic appliance by an amorphous blending of the interface between the base and body.
