hi it's dr. Amanda from straight smile solutions today we're going to talk about adjusting labial
bows and if you have a Hawley retainer labia bows are really useful this is kind of how we moved
teeth minor tooth movements before aligners were invented so we've been doing this for hundreds
of years and it's a really economical way to have some minor tooth movement lab fee on a
basic Hawley and this is a little bit more of a blinged-out Hawley but it's maybe somewhere
around 75 to 125 dollars depending on how much you bling it out how much you customize it so this is
a labial bow right here let's turn it around okay and usually it goes from canine to canine okay now
to tighten alle Bilbo you're gonna need two major pliers to adjust it the first one is called a
three prong pry plier as you can see here okay as you can see here it has three prongs easy to know
the opposite or the inverse of the three prong plier and both of these you should have if you're
going to be messing with Hollies is called a bird beak plier so a bird beak plier if you can see has
a rounded tip and also has a square tip so it has two tips one is round and one is square that's why
it's called bird beak okay so to tighten the three prong with a three prong plier you want
to find your u loops one two okay and then you're going to put the single the doubles on the top and
the singles on the bottom see that okay and when you do this this will tighten same thing on the
other side you want to tighten ever ever so small okay just a tiny little squeeze sometimes I'll
even tighten just by squeezing with my fingers sometimes I'll even tighten if I want to just
by taking the bird beak and compressing it like that a little bit goes a long way with tightening
you only need to tighten if when you try it in the mouth if there's clearly a gap between the
incisors and the bow the bow should be touching the incisors but it shouldn't be pushing on it
super hard you just want it lightly touching the incisors to be passive and if you want to active
you give it a tiny squeeze with the three-pronged plier and that's pretty much it now that is what
you do if you want to retract teeth pull them back or close a gap but that's only gonna happen
on the top arch if you have place to put them okay so when you have a holly like this there
is acrylic right here and there's a space between the teeth and the acrylic the teeth cannot move
if the acrylic is will adapted to the incisors so with the top teeth first of all you have to see if
there's even overjet if you get a bite I'm gonna show you example what I mean by this let's get in
a model okay if you get a bite say like this okay and if you look here the bottom teeth are hitting
the incisors is a matter of fact if you got a piece of articulating paper and put it right
here bit down and all around you would see marks up here if you see marks up here cannot retract
teeth with a Holly it's impossible because there's no place for them to go because they're hitting
the bottom teeth the only time you can close a diastema or retract teeth with the Holly is if
there's overjet okay so not possible in this case so that's one of the biggest mistakes that people
make when they think they can close the space or retract incisors bottom teeth shouldn't be
a problem because usually unless you have a negative overjet if you have a positive over
jet it shouldn't be a problem retracting bottom teeth and closing a gap with the Holly so anyways
that is your trick remember you're gonna need a bird beak and a three prong plier okay and
articulating paper is also really helpful if you need to remove acrylic you can just get a really
skinny acrylic fur and get in there and remove a little bit of acrylic a tiny bit at a time goes
a long long way a justice with the three prong wear it for a couple weeks to a month and then
repeat always check your with articulating paper to see if there's still clearance to do that and
that is my trick on how to use Hollies to close spaces stay tuned for more videos thank you
