let me first take a moment to explain
the key to the expander the key is
designed with this bend right here this
is a safety bend this prevents you from
poking the roof of the mouth while
you're doing the turns on the expander
when you go to insert the key into the
expander insert the key all the way up
to this first Bend and that's how you
know you're in the correct position okay
let me show you how to turn the upper
expander I'm going to show you on a
model of real close-up views so that you
can see what I'm doing what you're going
to do is take your key and insert the
key into the hole in the forward
position this is the hole towards the
front of the mouth go ahead and slide
the key into the hole until you feel it
hit that safety bend there then you're
going to push back towards the back of
the mouth until you see the next hole
rotate around into that forward position
that's one complete turn when you go to
remove the key be sure to pull straight
down to remove it and not pull forward
to remove it because as you pull forward
you can see you're reversing the turn so
instead make sure you pull straight down
to remove the key then what you're going
to do is always double-check yourself go
ahead and take your key and see if you
can replace it into that forward hole
again if you can you've done a great job
turning and here's what it looks like to
turn the upper expander in somebody's
mouth so you're going to take your key
insert the key into the hole in the
forward position or the hole closest to
the front of the mouth push all the way
back towards the back of the throat once
you see the next hole visible go ahead
and pull straight down on the key to
remove it and reinsert the key in the
hole in the forward position to check
your turn to make sure you've done one
complete turn okay let me show you how
to turn the lower expander again on a
model of a patient's mouth so you can
clearly see what it looks like you're
going to take the key of the expander
and insert the key into the hole that's
visible at the top of the expander once
the key is all the way into that safety
bend you're going to push the key back
towards the tongue and rotate it around
until you see the next hole become
visible on the top of the expander
that's one complete turn so you can go
ahead and slide your case straight out
towards the tongue
to remove it and again double-check
yourself by putting the key into the
visible hole again to make sure you've
completed your turn and here's what it
looks like to turn the lower expander in
somebody's mouth find the hole visible
at the top of the lower expander insert
your key into that hole make sure the
key drops all the way down into that
safety bend push back towards the tongue
until you see the next hole visible at
the top of the expander then pull
straight back on the key to remove it
and double-check your turn by putting
the key into the next hole that's become
visible and that's how you turn
expanders great job
you
