<p>An orthodontic bracket assembly adapted for securement to teeth of the upper and lower jaw is provided. The assembly is a multi- component system that includes a base component (18) and a bracket (22) component. The base component (18) is adapted for securement to a tooth (14) using an adhesive material (30) and includes a housing (47) having an integral channel guide (50). The bracket component (22) includes a flange (70) arranged for insertion within the channel guide (50) and is held therein by a spring clip (72). The bracket component (22) includes an archwire retention head for receiving and retaining an orthodontic archwire (66) therein. In one embodiment, the archwire retention head includes a tube (58) having an archwire tunnel (62) extending mesial-distally therethrough. The cross-sectional shape of the archwire tunnel (62) can vary depending upon the archwire (66) being employed and may provide a frictional or frictionless fit. The tube may be positioned at a predetermined location for correcting a maloccluded tooth.</p> |
