Clinical tip: Midline Correction with Intermaxillary Elastics｜【Chris Chang Ortho】CC451

- Abstract
Asymmetric intermaxillary elastics are often indicated for midline correction. However, asymmetrical elastics in the posterior segment often result in occlusal canting due to unwanted molar extrusion. To avoid this side effect, a recommended alternative is to use z-shaped elastics in the anterior segment instead of asymmetrical elastics in the posterior for mild midline correction.
摘要
改正中線常須借助不對稱的配戴顎間橡皮筋（Intermaxillary elastics），然而對後牙施展不對稱牽引會造成大臼齒的不當擠壓，使咬合平面歪斜。為了避免這樣的副作用，後牙應儘量避免使用不對稱的牽引，可改用在前牙區拉Ｚ字形橡皮筋，以改正輕微中線偏移問題。

As a person who is in this procedure to correct midline shifting, it is good to know what my orthodontist is trying to do to correct my midline as I always want him to explain what he is doing and what process I’m in but he’s always in a rush. This helps me a lot. Good to know! Thanks a lot!
Orthodontics is fascinating!
Why am I even watching this? I'm not a dentist
Thank you for your watching.
😂😂😂
Because you are captivated
Thx Dr Christ Chang for your lesson ❤❤❤
I think, the important moment under such influence is rectangular arcs. It is also necessary to take into account the final molar ratio. The arcs must be fixed to prevent slipping in the grooves. And I do not like clamping hooks.
Smart solution. Other possibility its use an elastik from 23 to 43... or a heavier elastic than the other side.
Not good. Incisors are sensitive with direct vertical force. It will cause extrusion.
Excelente trabajó del Dr.Chan
It hurts so much its torcher every single minute
hello dear Doctor
hope you are doing great
I want to clarify some points if u don't mind dear doctor, 1. The long class 2 elastics in posterior segment + z-shaped will neutralize the effect of clockwise cant rotation ( the moment and force ration in long class 2 elastics produce big moments as u mentioned in the beginning)? why u didn't use only z-shape elastics?
2. the z-shape elastic ( between upper central two opposite forces will equal 0 + on lower canine to premolar will it equal zero? then from 12 teeth distally to lower 33 teeth mesially will act like short class 2 but the force direction is to the upper center of Resistance so will have translation movement of maxilla but due to distance between force and center of resistance on the lower arch will still have some moment right?
thank you for your knowledge dear Doctor
hope to meet you one day and learn more from you
good job thank you
My orthodontics are so stupid. I have the last case and they put the elastics in the same directions (CII elastics), making the midline even worse. When I told them or recommended to put the elastic in differing directions (CII and CIII), he agreed with me. But now I am worried about my canted smile even becoming worse as I already have right upper teeth more intruded. It is so frustrating. Is it rude If I show them this video?
So... you told/recommended them to do something... and now you’re complaining about your own recommendation??? Maybe stop trying to be the doctor just bc you watched RUclips. Just a suggestion. 😄
How is your teeth now?
@@johnh5149 Obviously I missed your reply but listen Sherlock, I was complaining about the risk of occlusal canting as shown in the last case. I am not the orthodontist, they are so When I brought up that my midline is off and advised elastics in different directions to line up the midline, they SHOULD have known about occlusal canting and the elastics SHOULD have been exactly as the last case....NOT just class II and Class III. My upper teeth are concaved in because of that reason now.
Ps; after SIX years of braces, I learned the hard way that NOT everyone knows what they are doing and you have to speak up and express your concerns.
@@celciemacabinguil9508 It is much better.....about to remove it in a month or two.
@@gdaebb9179 you had the braces for six years??? I did my braces just yesterday. What do you recommend me to get done with my braces within two years max. My case is midline discrepancy and bite correction and I’m adult. I wish you all the best.
I had perfectly aligned set, but after completing the treatment ( to push the teeth back), I realize my teeth were no longer aligned. I consulted with the same doctor who did my treatment, about my concern. To this the doctor suggest that the only way to fix this is by pulling out one healthy tooth to have enough space to move teeth for aligning.
This video, show there is no need to pull out healthy tooth in order to do the aligning.
this video is a simplified example to make people understand. not everyone have the same set of teeth. alot of other factors to take into account
Hi, what Is the best arcs to use elastics for II or III class to have best results?thanks
Nice clinical tip, but check the last part of the presentation. I believe the patient's left side should have a Class III elastic instead of a Class II. Let me know if this is correct.
Si, me parece lo mismo. Avísame si esto es correcto. Gracias.
Jerry Smith I feel same
Jerry Smith Same question.
I have a CLASS II DEEP BITE and my orthodontist has almost concluded my braces journey albeit I still have them on. I have a major midline discrepancy on my bottom teeth and she says it’s normal and can’t really be fixed. I feel very sketchy and want a second opinion. Who should I go to for getting this checked out? Can it be done online by any chance?
Same!!! Update???
@@Klarisszaivncsk i changed my orthodontist and my new one worked on fixing my bite and it has significantly improved over the past month!! i have 4-5 months worth work still left with elastics and i’ll get them off!!
@@minimistu did you have to pay some extra money at your new ortho because you already had the braces on??
@@Klarisszaivncsk yes but luckily it wasn’t as expensive since I didn’t pay my last instalment at my current ortho so it kind of compensated for that.
@@minimistu i called an other ortho and they said they have to take off my braces and put a new one on and pay for it. Lmao. So you didnt have to do this? Did you bring your old papers/x-rays to your new ortho?
我認為這樣仍然會產生咬合傾斜
what if top is already middle
only lower teeth need adjusting
Zen Kantaphon they would still Have to give you braces for your upper and lower row
if it’s after braces it might be because you are still used to biting down with crooked teeth
No decent answer till now.. haha
Great tip
I am at the end of my treatment. The Clockwise Rotation U1 Q Loss is what my Dr. is trying to achieve right now. However, I keep trying to tell him that this has only moved my 1st molar, with no movement of the K9 tooth at all. It has not only pulled the molar in towards my tongue, but it also pulled it out some. To the point that I have now grinned down the tooth. I’m starting to lose my patience with my Dr for not listen to me, but now I am mad. What should I do?
Are you an orthodontist?
wsyd? stop winging and crying
It's necessary to create space in a dental arch to correct the midline?
Thank you.
I think left side elastic incorrect in last part? It must fit from UL6 to LL3 instead of UL3-LL6?
I don't think there is nothing wrong with the final diagram. The LHS should be a C2 Elastic, If you use C3 elastic on LHS you will make the cant worse.
He put mine on Parallel and on the video it said no to do that. I’m scared now
This adjustment is possible in adults over 35 yrs??
Occlusal cant will not happen. Yes in theory correct. But in practice it won't.
I’m victim of malpractice by Federico Hernández Alfaro (maxillo Monkey-facial Institute in Barcelona). Looking for an experienced professional for the revision this time.
I think my orthodontist is doing the first one to correct my midline because i'm missing a canine on my upper teeth... Can someone enlighten me with risk on this
what about presence of insufficient overjet? still cl 2 elastics?
Soundtrack please
Lol that's exactly how my teeth is
Me parece que el señor Jerry Smith tiene razón. Avísame si esto es correcto. Gracias.
How to get treatment from nepal ?
I'm interesting in fixing teeth,but I don't have tools to learn
For the intermaxillary elastics, was it a single elastic or three?
Can braces fix weak chin
The Z shaped elastic consists of 3 different elastic or single elastic?
The same, thank you, my friend!
Z shaped elastics, is it three pieces of elastics to create the Z or just one? @@ChrisChangOrtho
They’re making me wear 1 on 1 side and 2 on the other and i feel like its messing up my teeth 😭
if upper midline and lower midline is wrong, the z-shaped elastic will effect both uper and lower midline.In case , only lower midline is wrong ,so I want to correct only lower midline. How should I use intermaxillary elastics ?
Try TADs in the lower arch with elastics to correct midline
Excuse me Dr., what kínd of program use to do that video?
now i understand why my occlusal plan was canted, My doctor corrected my midline with classII elastic on a one side and class III elastic on another side :(
Did he fix this for u somehow? Because i have the same problem But didnt mention to him yet
@@Klarisszaivncsk no, i removed brackets and the problem isn't resolved completely.
Good
Здравствуйте скажите а вот ставят коронки они вообще могут перетерать пищу как своими родными или ето для красоты ставят
Bro music?
Why warning
This is my problem, do you have clinic here in the philippines?😊
Ganyan Yun akin Hindi magkatapat 😢 sana maayos ni dra
Nice.. love that.. duration how long to use the elastics and how to rwtqin this after treatment..can u pls explain..thank u
Can midline shift of teeth cause jaw assymetry
sadly yes
My bottom midline was centered with my top before my braces, now it's moved off to the left and I have a big gap where I didn't have before. I still have two years to go and my orthodontist has said it's part of the process. I hope she's right, but I really don't understand why she would mess up my bottom midline. Is this normal for some people?
Hello, I hope your okay,. I ask Kriss Ai about your concerned and it said Midline shifts and the creation of gaps can be a normal part of the orthodontic process. Treatment often involves moving teeth in stages, which might temporarily cause these changes. Trust the process, as these temporary changes are steps toward achieving the final, optimal result. If you have concerns, communicate with your orthodontist for clarification. Remember, the journey may have temporary inconveniences, but the end result is usually well worth it. I hope this help.😊😊
@@rienne89yes, I'm okay, I hope you're doing well yourself and thank you for responding to my concern. I spoke to my orthodontist this week when I went in to have my wires changed and she said you have to mess up your mouth first in order to correct it. She looked at my midline and said she would be bring it back over in time. Everything right now looks and feels off, I just have to realize that it's the end result that matters.
@@rienne89 Can you tell me more about that kriss ai?
Can anyone tell how long that takes?
4 months i think
What size is Elastic used for The Z shaped Elastic ?
you prolly dont give a damn but does someone know of a tool to log back into an instagram account??
I was dumb forgot the login password. I would love any assistance you can give me!
@Ulises Shane Instablaster ;)
@Musa King thanks so much for your reply. I found the site through google and I'm trying it out atm.
I see it takes quite some time so I will reply here later with my results.
@Musa King It worked and I actually got access to my account again. I'm so happy:D
Thanks so much, you saved my ass :D
@Ulises Shane Glad I could help =)
what if my bottom teeth are like...they skipped a tooth to the left? how can i fix that?? 😂 yes the midline is not in center
How much time it takes to finish the midline treatment ?
This will depend on the circumstances.
name of the song?
that's what i'm looking for! haha
My dentist told me that I have to extract a tooth so that I can have my midline corrected but my the lower part is shifted to the left while the upper part is to the right and he said he needs to extract my 2nd molar at the upper left part . Why??
It depends your won situation. Please consult with your doctor.
im having the same thing, i already got a tooth extracted from the upper right tho..
@@naaimamasood2199 I'm not happy with my progress
@@marielsalem9053 whats ur progress? and how long have u had braces for
@@naaimamasood2199 2 yrs and 9 months, my doctor said that its done already and we are in the healing process but I'm not happy I still have deep overbite and my midline shifts to the right. The first 3 teeths on the right side are still slanted for me
Can you fix midline correction and or canting with TADs?
I think we can. Please go to consult your dentist. Thank you!
Does anyone know how long this process is?
May be as early as 3 and as long as 8 appointments as far as in my practice
Its been a month for me and i havent seen any much movements to my midline yet
Did anybody else got grossed out from the thumbnail?
😊
Hi Doc, may I know the size and oz of elastics?
your orthodontist chooses according to your case and treatment
3.5 oz is the force. Size depends…
Orthodontist are loosing their jobs now🤣🤣🤣
?
With ur presentation method and teachings every BDS doctor will be confident to do ortho cases, then what will the orthodontist do.? Obviously they won't be having so many cases. Jobs lost. Right.
How long does it take to be fixed roughly? My teeth are straight and only my centreline is wrong. I’m wearing my elastics daily but they don’t seem to be doing anything. I really want these bad boys off
This is whats happening with me.
same i had elastics two times but they are not working my centerline is still messed up😀
Itsme Angel thank you 🥺❤️
Same. Been wearing elastics for a while & it doesn’t seem to be moving. I wanna cry lmao😢
same and i get my braces off in a week.. my midline isn’t perfect yet
Good
what if there's premature contact that causing the functional shift?
؟؟
You mean like this? ruclips.net/video/IyVrILWJVp8/видео.html
My midline is off like the first patient but my teeth aren’t that flared out I hope my ortho fix this
my dentist does the opposite of this. i’m worried
What happened
That’s literally my teeth right now
Eso me pasó a mí y ahora tengo problemas de oclusión....
Hi, for the class ll and class lll on 2:26 how long will it take to fix the midline for this type of bite, I have it
What U1 Q loss means
kriss ai said that tt could be a technical term, a code related to equipment operation, or something specific to a particular document or system.
Can I get elastics without getting braces?
This is exactly how I have to wear my elastics right now
My middle line is incorrect. I think my ortodentist don't know this. He didn't put my rubber bands like that
He put mine on Parallel and on the video it said no to do that. I’m scared now
Mine has midline problem the doctor said she gonna pull out one of my teeth. Is it effective?
Everyone has specific cases. We can't help you with that. Sorry
dont ever pull out your teeth its gonna make your face look worse
Bravo! Pure physics 🎉
Isn't it the orthodontist's job to prevent that from happening?
My upper is now midlined but its my lower that is SUPER off the midline and my smile became crooked. And my ortho told me that I only have 3 months. What should I do?
Did he fix it???
@@Klarisszaivncsk Nope, and I'm already hopeless about it
