hey it's dr amanda with straight smile solutions straightsmilesolutions.com and today we're
going to talk about when do you stop using elastics and if you go into my youtube channel
that's not youtube in general but my youtube channel straight smile solutions keep in mind you
can always use that magnifying glass towards the top right to search for any keyword like elastics
or class 2 elastics etc but specifically on the home page of my youtube channel straight
smile solutions there is a playlist all about elastics because you use elastics for a lot of
things not just for braces also for invisalign and other things so go ahead and check out that
playlist and you'll get all the information you need about elastics and as always my youtube is
free it costs me money to make it but i give it to you as a gift back to the industry for free
as a thank you i really would appreciate it if you'd slap that subscribe button please
subscribe to my channel and tell others about my channel because i can only keep my channel going

tell your friends and colleagues specifically i would prefer that dentists know about it so post
it on those facebook message boards you know tell friends and colleagues to follow it and if anyone
needs help with an orthodontic case that's what we're here for just go to streetsmilesolutions.com
and check it out alright so the question today is when do you
stop using elastics of course there's tons of different elastics these are the four most common
um configurations your class two your class three your triangle in your box triangle can be all
different types of triangles this triangle here i made it from three three six you can also have it
be three three four you can have b three three five you can have it be an inverted triangle um
like four three four like this doesn't matter okay a triangle is a triangle a box is normally
three three six six but it could also be three three five five it could be four four
four four five five it could be four six six four you get the idea right box a triangle whatever
you get it okay so i don't normally i use at the if you watch my wire sequencing videos
and treatment sequencing videos again other great keywords for you to watch um i talk about what how
i tackle cases and part of this is how i learned the residency and part of this is just learning to
streamline things um and it works for me really really well and i find that most assistants
like this you know goes well in their office too so um you know obviously braces go on you're
in some type of initial leveling and aligning wires which is usually going to start with a 12
usually a 14 or 16 or an 18 night very rarely at 12 night time i'm going to try to get in the
biggest possible round wire that i can get in so i don't have to change wires anytime soon
but only that i can get in if the wire is fully in the slot that's the most important part if the
wire is not fully in the slide then you're in the wrong wire you know especially if you can
if you're trying your best with one of those literature directors or a figure eight or a
steel tire or whatever okay so you get the idea so you're on your initial wire whatever that is
and let's say we have one of those cases where there's like a high canine you know a tooth that
needs to erupt or it's kind of blocked out buckley a pie then that's when i would use a triangle okay
obviously this isn't really necessary here but this is just showing you the orientation
what about box elastics box elastics i use when we have a deep bite
and i've decided i always on deep bites i always put on either anterior bite turbos or an anterior
bite plate if you want to know when to use when i have videos on that you can search by keyword
lots of content how to make them how to build them how to make the route lab slip etc
um then when you do that you're gonna have a posterior open by it once you place those um
appliances or auxiliaries in and that's when i use the box elastic to help several settle the curve
of sp in the back so for triangles to answer your question since that's what i use triangles for
obviously i'm going to discontinue the triangle once that tooth is an occlusion that's easy right
if you're not sure use articulating paper for boxes i'm going to discontinue it depends on how
big you've made the ramps or how big you've made the how thick the lab has stick the stacked the
acrylic on the bite turbo it's not a requirement for the patient to wear box elastics but it helps
to speed up the amount of time so that they can get that appliance out quicker which is
usually their goal so i like to enable them they don't want to wear it fine we'll let gravity take
its course it's just going to take two or three times as long their choice they want to wear it
so um i give them this i say if you want to speed it up you wear them if you don't you don't it'll
just take a lot longer so i mean we'll keep going with our braces it doesn't matter to me
so usually if i'm not sure i want to get at least a couple teeth into occlusion with
the plate or the turbos in there check with articulating paper a couple people
in occlusion a couple teeth and occlusion on both sides not just like one at least two sets
on each side and then i'll take it out but if i feel like they maybe stack the acrylic too thick
pop the appliance out it's always good to do that so they can brush and floss check the bite i want
to see it almost to an open bite state like almost zero you know to ten percent in terms of vertical
you know instead of i'm sure they started at like 90 to 100 percent you know almost full
impingement so i want to see it over corrected by a little bit and that's when i'll take it out
but if you're not sure like i said you can pop it out check the bite with articulating paper
um but yeah that's pretty much when you finish box class two class three tons of content on
that obviously when you've corrected the class two or class three i mean that's not that hard right
so i mean clearly it's not that hard this is and keep in mind this is not the
the right type of orientation so obviously we're class one here but when you've taken the class two
you've closed the space and you're now in class one then you can stop the class two elastics now
if you have one side where you are still slightly class two on one side where your class one
you can always just wear the side where you finished at night time only and you can wear
the other side full time so that's kind of my little hack for that obviously with class two
cases if you start to get to an edge-to-edge bite well then you better discontinue if you
fully discontinue sums it'll relapse so i like to go to nights just to be safe for a month or so
um class three obviously when you start getting positive overjet you're going to discontinue
same thing i usually just go to nights all right hopefully that was helpful thanks so much
