<p>The present invention relates to a two piece fixed functional orthodontic bracket appliance (10) to which a flexible archwire (32) can be engaged. This two piece orthodontic bracket appliance (10) allows for constant mobility through a full range of orthodontic tooth movement, and provides for greater innerbracket distance. It also allows free sliding of wires through its components in such a way as to reduce binding and friction. It also provides an irregular base (60) which promotes mechanical bonding to teeth.</p> |
