The left canine relationship is Class II (Fig.3).  Both the teeth #12 and 13 are suprarupted, while #13 is nonsalvageable.  After extraction, an immediate implant will be placed distal to the socket so that once it is osteointegrated, it will be used as an anchorage to intrude #12 and distalize #9-12.

The implants at the sties of #20 and 21 are placed a little distal so that there is space to distalize #22 slightly.
