hey it's dr amanda with street smash solutions street smile solutions.com and today we're gonna
talk about arch wires yay you guys always have so many questions about archwire so i'm gonna
take you through my opinion about archwires what i use them for what i don't i have tons of videos
on archware's already if you want to watch all my straight wire archwire videos you can go to
my youtube channel which is straight smile solutions so go to your youtube channel put
the word straight smile solutions in the search bar it'll take you to my youtube channel which
has a green banner then on the home page there are a variety of different playlists there's one
for straight wire or braces you can watch all the hundreds of videos in there and learn a lot about
everything you know free orthodontic education but let's just do a quick video specifically i
want to talk about tma today which is one video that i hadn't made yet tma shoot i
should know what that stands for and i totally forgot but it's it's basically beta titanium
is another word for it a beta titanium is a hybrid material that means it's somewhere in between
your nightie and your stainless steel is it okay so it's got some properties of both in there
turned into tma okay so what properties does it have well let's talk about knife type so we've got
our night we've got all kinds of super elastic knife ties i've done videos on the difference
between copper nighttime regular night time reverse curve nikai thermal activated nighttime
there's a lot of different knights out there whatever personally in my opinion just do regular
night time you really don't the benefits and the extra expense really don't make it that important
so what about the properties of knife iron well nighttime is nickel titanium it's a super elastic
wire it used to be pretty expensive it's much cheaper now of course the cool thing about it
this is a o2o so it's round so you can see what it is it says upper okay and it says
o2o o2o if you only see one dimension means it's round and the dimension is o2o of a millimeter
um so it is that's a pretty thick round wire so when you bend it it bounces back
see it doesn't actually make a bend you can stick it in all the teeth and blah blah and engage in
everything and then boom it just goes back right pretty cool stuff that's so the teeth and the arch
take on the properties of and the dimensions of that wire of course you want to pick the right
arch form for that so this is a natural arch form every company calls them different things
they might call a natural standard oh boy they might call them square tapered and ovoid whatever
pick one company and stick with it that's the main thing this is a pretty nice nice arch form
i like it it's nice and rounded okay there's some that are way too narrow they're like
this we don't want those okay because everyone's a nice broad archwarm we don't want something like
this that's a little ridiculous this is a nice arch form just make sure you stay with the same
company for all your cases and pretty much the same arts form occasionally i'll get an
adult where i'm like okay we can't expand these arches um they're just too narrow you know we're
gonna have to stick with them more tapered arch form but that's pretty much few and far between
so for the most part for most your patients you're gonna stick with it standard you need
to make sure you have an upper on the upper and a lower on the lower there are a few straight wire
courses that are out there i call them courses and air quotes that use universal that's a huge
mistake you're going to have some funky back teeth bites so you always want to use upper on the upper
and lower on the lower and it'll say lower if you have lower i don't have any hair right now but
you can see upper o2 round wires like this are meant for leveling and aligning which is their
first stage of doing it it's not meant for space closure okay no power chain on these it's not
meant for open coil springs none of that it's not meant for elastics the only thing you're doing
with round wires is leveling and aligning once you've finished that you're going to move on to
rectangular you can do more things with rectangular okay sorry that's tma but you
get the idea okay so let's find some other no i don't have any other rectangular ones but anyways
okay so upper on the upper lower on the lower round for leveling and lining rectangular heavy
rectangular for other types of movements like elastics open coil springs add power chain okay
like we said tma has properties of both knight and steel here's stainless steel okay so we saw what
happens with nighttime when you bend it let's get stainless steel out and see the difference
between that is if i do that with stainless steel sorry i was out cleaning my car today
and my nails are all black so um but you can see stainless steel when i bend it it stays bent okay
that's the difference why do we like this well we don't like that for leveling and lining but i like
this if i want to make a bend in the wire now as a general or pediatric dentist do i recommend you
deal with beds no don't do it no point just get your brackets right to begin with so most general
and pediatric dentists that i work with will never use stainless steel wires they just don't need
them why there's no reason for them even me as an orthodontist barely uses these anymore now do i
think you need tma no i don't think you need that i wouldn't even bother buying it i used them a lot
in residency because our residency was really into like cantilevers and weird kind of biomechanics
now there are more efficient ways to get things but they taught us all the basic ways and we used
to make cantilevers out of tma um we also used to make intrusion arches out of tma so it had
some of the benefits so i'll just open it and show you these are kind of expensive but i'm going to
wrap one so tma has some elastic properties like the nighttime but it also has the ability to be
bent so i can do this and you can see it bends right but it also is a little bit elasticky
oh my god this is like a five dollars i just threw out the window but yeah tma is very expensive for
that reason i don't think you really need it i don't think you need stainless steel either very
very rare i'm not saying never buy it but maybe have a few packages but it's very rare that you're
ever going to need it assuming your treatment plan right you use expanders when you need to use them
and you use indirect bonding for your bracket placement and place them right to begin with and
you if you're not using indirect bonding for your bracket placement you're stopping at your 18 nikai
and doing taking a progress panel and doing your re-bracket appointment and getting your
brackets right if you're not getting your brackets right to begin with you will need to do bends and
i don't think i don't think it's worth your time to be very honest to learn to do beds it's
a complete waste of bright space and time so all right so that's pretty much it in terms of the
difference between tma or beta ti nitai stainless steel only other thing i really wanted to talk
about today is the coated wire here's a coated wire i wanted to talk a little bit about that
cool thing about coated wires is that they're kind of pretty you can see this one is white
i've seen them in blues greens oranges yellows so you can do coated wires you know for patients that
want more colors you know problem is these coater wires don't have the same properties as a regular
nighttime to me things move slower so it's not something that i offer i i have ordered offered
the coated ones before but these always flaked off like the coating it looked always kind of gnarly
so i mean do i recommend doing that no but i just wanted to bring it up to you
well the other thing i want to talk about today is the reverse curve wire and i've done
other videos on that so make sure you go into my youtube channel put in reverse curve or rcs
rcs reverse curve of speed wire and it explains what a reverse curve wire is for or an accentuated
curve it's the opposite same wire make sure you keep upper with upper lower with lower right
but they're very handy i only do these at the very final wire the last two months let's say i
have a slight deep bite that i want to open and everything else is straight i don't necessarily
want to go in and do a bite plate or enter a bite turbos because i don't have to go back to
a nighttime wire and use box elastics maybe i don't feel like bonding the sevens because that
takes a lot of time and they tend to break off and i just want to open the bite a little bit
or i have a slight open bite i want to flip this over on the top to get a little more extrusion
of the anterior teeth that is the benefit of this i think this is something at 1925 that you
would want to stock both upper and lower i would highly recommend it these do really come in handy
but they're only the last few months you do not do them at the beginning of treatment like case
is done done done we're just trying to either open and close a bite at the end that's what i use them
because if you start mixing these up in the middle of treatment it's you're going
to waste your time and money because these are expensive so anyways all right hopefully
that was helpful hopefully you learned a lot about wires again if you want help with a case
we help with individual cases as well as you can get a subscription a monthly subscription
we help you with all your cases we can help you screen your cases do your treatment plans help
you with your clinch checks i'll show you about bracket placement tell you what wires to use what
mechanics to do to try to get your objectives etc etc take you to help you with new services like
hey let's go into interceptive let's do growth modification invisalign bionators twin blocks
really fun stuff like that expanders sagittals molar uprighting all that definitely cool
that's my favorite stuff that's out there all right thanks so much have a great day
