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 and a bracket component. The base component is adapted for securement to a tooth using an adhesive material and includes a housing having an integral channel guide. The bracket component includes a flange arranged for insertion within the channel guide and is held therein by a spring clip. The bracket component includes an archwire retention head for receiving and retaining an orthodontic archwire therein. In one embodiment, the archwire retention head includes a tube having an archwire tunnel extending mesial-distally therethrough. The cross-sectional shape of the archwire tunnel can vary depending upon the archwire being employed and may provide a frictional or frictionless fit. The tube may be positioned at a predetermined location for correcting a maloccluded tooth. |
