Order your pre-surgical wires before the post-surgical wires, as you will use the pre-surgical wires first.
The pre-surgical wire should do most of the work as it moves the teeth to their final or near-final position before surgery, so that after surgery the amount of force and tooth movement needed is minimal.
Caution: Do not copy a post-surgical wire for use as a pre-surgical wire as the surgical movements will be copied as well.
