case ${dir##*/} in

esac

Note that find's output is not post-processable unless you use
some trick or can guarantee that none of the file names contain
newline characters. find has a -exec predicate, there should be
no need to use a while loop.

read alone is for something very special. If you want to read a
line of input, it's IFS= read -r dir.

Note that there's no guarantee that the while loop will or will
not be run in a subshell in the code above. So if for instance
you do a cd in that loop, it may only change the current
directory of that subshell.
