En masse protraction of posterior teeth- A novel approach

Published in American Journal of Orthodontics & Dentofacial Orthopedics (Chhibber A, Upadhyay M. The en-masse protraction of mandibular posterior teeth into missing lower lateral incisor space using a fixed functional applianceAJODO: November 2016):
Thank you doc for the eye opening information that you shared about aligner mechanics and materials. It clearly states that why someone is struggling with aligner for the difficult tooth movements. highly recommended..
hello, i have a few doubts, let us hypothetically say im working smthg similar for my college project, but id like to make thee concept more accesible, im planning on developing a application, for this where u take photos from ur phone, instead of using xrays, to plot the landmark points.
would u recommend this? in that case, the landmark being within 2mm radius might not be possible(not clinically accurate i think), will that still be worth it?
Really interesting! Is this available somewhere for testing? The QR code doesn't work anymore.
Great lecture... Did you have an engineering or heavy classical physics undergrad experience? Biomechanics? Would love to hear how you approached this early in your quest to understanding, thank you.
Thank you so much Doc
Sir, can we apply PAOO in aligners too. Kole's procedure.
Yes, of course. Aligners are one of the many appliances that are used to move teeth. PAOO as it claims is used to accelerate tooth movement. However, as you will experience faster tooth movement, the aligner side effects will get exaggerated too. (orthobites.org).
Very impressive lecture. Great job !
P r o m o s m 😣
Dealing with the nasty virus called HPV was not so easy, but now I can testify to the world 🌎🌍 that I'm negative after using #DrBalogun herbal medicine 😊
Very well demonstrated and explained sir... Thankyou so much for this 🙏
most studies are quite old. isn't it possible that the technology of the aligners has changed the information in the video?
32:57 Is just like roller-coaster effect if we use NiTi 0.016. Or 0.018 or NiTi rectangular wire Instead of using SS wire we get this effect and its called rolorcoster effect same is coming with these aligners from my opinion if we use 2mm sheet with power riges on incisers on gingival area we can get translation movement
Great lecture and presentation. Thank you so much Dr Madhur Upadhyay
Great presentation Thank you so much for sharing really appreciate it!
Excellent lecture
Thanks a lot Doctor
Hi Doctor Thank you for this great presentation.. did the aligners closed the space in the case you started to treat ? Do you provide mentoring services to general dentists in doing orthodontics treatment ?
🙏
So is it true that there is no point in using aligners instead of braces? I was just about to start studying aligners to use in my practice
No knowledge can help Juliana the boy, very difficult mental case.
I have a question , so when you mention the % in the tipping , you show a teeth with a torque movement , I do not know if its a language difference cuz my native language is Spanish , so this movement that you show is tipping or torque ? It confuse me cuz I want to know when I need to use thicker aligners , for torque movement or tipping movement
Broadly tipping comes in two forms: uncontrolled ( root moves in one direction and crown in the other) & controlled tipping ( minimal movement of the root). The tipping movement shown at 25:20 is more toward uncontrolled tipping (UT). Here there is no torque being used ( because that is the classical definition for UT). CT needs some control over the so there is little torque used. Thicker aligners might help with torquing movement, however the evidence is not there.
@@orthobitesorg thank you for your answer
Excellent lecture.. learnt a lot about basics of aligners
Yo is it harmful for reproductive help???
Great lecture. Honest one.
Thank you for your helpful lecture. At 6:27 when force is applied to the tooth, it rotates around the center of rotation which is not necessarily the same point as the center of resistance
Too confusing

Dr. Madhur - Would you be kind enough to share the link of Biomechanics - 1 as I am unable to find it on CZcams...

Excellent work. Where can we get update about this project?
Thank you. It is being worked upon. The full paper has been published. We are using similar projects with our community and in our courses. courses.orthobites.org/courses/first-principles
I need your help! My dentist had me change trays everyday (I didn't know this was unusual) but he had 0.056 mm activation per tray maybe even more for a total of around 1.4 mm. :( 25 trays in 30 days with IPR between tray 15 and 16. No one can help me decide if more damage than just my incisor dying happened because no one knows how the force was applied/compounded. I manage to get my tooth movement table and the staging should be even over all teeth over all 25 trays. 0.392 mm/week velocity attempt with 1.4mm/month total Would you consider this excessive or dangerous? Would you help me figure out what happened on some level?
Great lecture
What a great lecture.
Thank you!
Great lecture but I am still amazed when I hear root movement or tooth translation cannot be done efficiently using aligners specifically invisalign. Building gable bends for the teeth being translated in your clincheck combined with a vertical lingual attachment and a bevelled horizontal offset attachment on the buccal will yield predictable results all the time. All these side effects can be negated by overcorrections in the opposite direction. Cannot extrude posterior teeth you might say? Well how about building a reverse spee wire into the clincheck and having the right attachments, not breaking the aligner biomechanics rules, and see how fast you climb out of a deep bite. It works you just need to micromanage every single tooth.
Great lecture! Thank you for sharing!
how could i get this software?
thank you
Pongan subtitulos pues. Para q todos podamos entender
Done. Please check if the subtitles are showing. However, we cannot guarantee the accuracy of the translation. Thank you.

Hello did u use a symmetric or an asymmetric V-bend?
They were symmetric bends
