Ultimately this is pretty easy. Not too many variations.

“please fabricate u/l fixed expander with buccal tubes”

or 

“please fabricate u/l fixed expander”


This is pretty standard for fixed if you want to archive the script for future patients.

Only variation would be one of the following:

1. Please solder anterior bite plate
2. Please solder facemask hooks

3. Please solder tongue/thumb crib
