Fig.5 is a mirror image of the upper jaw (palate).  In addition to the rubber band in the front (black *), a mini-implant (M) and T-bar (white *) are used to hold the front teeth as a solid unit (anchorage. fixed point).  A spring (>) is used to push the back tooth (6) backward (-->).  When the tooth #6 is moved backward enough, a new brace will be place on the tooth #5 (not shown).  The tooth is to be pushed back in the same way.  So forth and so on for the teeth #4 and then #3.  Last the teeth #3-6 are tied together as an anchorage in the back to drag the 4 front teeth backward (2,1 and the other two).  Return to main article
