Basics of Biomechanics 2 (types of tooth movement and couple)

This video gives you detailed explanation about the physics of single force application on a tooth and resultant movement you achieve. how to calculate moment and what is couple.

Thank you so much !!! You are making clear knowledged and successful Orthodontists

[@mukhammadrizorakhimov2088]

best explanation that i have ever heard. Greetings from Uzbekistan.

[@safiariaz9287]

I was struggling to understand this for an hour now , before I found this Alhamdulillah.. I can not thankyou enough for making this easy for us. jazak Allah

[@KyawSanLynn-sl2qu]

I didn't understand about 'couple force' befor watching this video .Thank you so much Dr

[@KeerthiK-dw9vg]

You are a really good teacher sir

[@Aapke_dant_ki_doctor]

Thank you for this!! My professor asked conceptual questions in viva which they never taught to us, but you did so nicely, i have started loving ortho and dentistry, i mean how beautiful all this,!!❤❤thank you so much!!💖💖

[@navyyahsree1320]

Biomechanics was this simple??? Amazing & good work

[@SamiGB1994]

I swear some concepts i did not understand it any time before till I watched this series. Super respect from us to you dear Doctor 🌹

[@zrational7882]

You are a really great teacher

[@deepasharda6289]

Thank you for a great video! Explained so clearly and simply.

[@khan-ey3es]

Plz make a full series on malocclusion, from introduction, classification to treatment of each

[@khan-ey3es]

Oh plz make a full final year series, i have never found such ortho videos, thank u so much sir And plz consider my request

[@aueaungulthopunyanont3927]

thank you so much, I really appreciated this

[@evonnesutherland9727]

You are a genius. Thank you.

Excellent Dr. thank you so much 🌺🌺

[@poojabs8125]

Very nicely explained 👌🏻

[@DrDen-t5k]

At 7:23 when root moved right side by couple force ,crown also moved in opposite direction then how it is different from uncontrolled tipping

[@irfansinstituteofclinicalortho]

You are almost right in saying that. But there are differences 1. Simple tipping is known as uncontrolled because it's just a response of tooth on single force while here in pure torquing, it's in your hands where you want to move the root, labial or lingual 2. Here you are applying just couple 3. In simple tipping center of rotation is slightly apical to center of resistance not here is exactly on CRes

[@DrDen-t5k]

@irfansinstituteofclinicalortho sir I'm actually confused in a point that. When we are referring moment of force cancel out by or balanced by moment of couple. If I take it literally that would mean moment of force representing one force and moment of couple representing 2 forces . That should make it 3 forces? If there is only two forces action.then we don't call it like one moment of force balancing 2nd moment of force. Why we say it like moment of couple is balancing moment of force

[@irfansinstituteofclinicalortho]

@@DrDen-t5k exactly. There's a single force resulting in moment of force. Then there's a couple resulting in moment of couple. But actually could itself is composed of 2 forces. If you consider it separately then these 2 forces also have 2 separate moments but collectively we call it moment of couple. I would recommend to watch part 3 of this series that will clarify you more

These lectures are very helpful!!!

[@hifzanaseem4923]

Thank you so much sir. Keep uploading the same informative videos.

[@irfansinstituteofclinicalortho]

Hahaha finally ;)

[@srijaidhanvantaridentalcar4063]

Best explanation Dr...

[@arfarehmat7607]

You are amazing doc❤️ Thankyousoomuchh for this conceptual lecture. God bless you.

[@irfansinstituteofclinicalortho]

Thanks a lot :)

[@nibeditasarkar6591]

omg so nicely explained ...

[@multinet_1667]

Thank you for making concepts easy to understad ❤️ Please make concept of interrupted and intermittent forces clear

[@imxylius]

very knowledgeable Please make more videos

[@sonalbarnwal7602]

Very impressive vedio

[@meenajayapal8902]

Thank u sir please upload more videos about diagnosis and treatment planning

[@shreyakarmakar4909]

Thanks for explanation 🙏

[@sivakrishna178]

Sir superb way of presenting sir ...please do make vedio on functional cases sir .....your vedio once watched it is like life time impact sir ........please do make vedio on diagnosis of functional jaw orthopaedics ...how to know clinically which jaw is deficiet anteroposterior ly

[@MuhammadBilal-wt3vv]

Wowww

[@su-huihung1551]

Could you explain different springs used with straight wire? like powerchain, etc? Stuff we often see in a clinical setting?

[@gnanasangamam7493]

Sir, 👌👌👌👏👏🤗

[@Nabilashariffff]

Thank you ❤

[@MartinGeorgiev-zp6nm]

The movement that you show at 8:05 is it possible in reality? Wouldn't there be some restrictions from the bone to prevent movement of the root at such a long distance?

[@irfansinstituteofclinicalortho]

Movements are always gradual in orthodontics and of course bone will resist too. But bone resorbs on force application. Secondly, when we try to learn biomechanics we have to neglect all other factors and focus on just force and its 3 dimensional response on tooth

[@zarghunashakur1264]

AOA. Sir your lecture was amazing. My requests would be to keep on uploading videos reakted to biomechanics. Also can you please make a video on one couple and two couple systems

[@irfansinstituteofclinicalortho]

Ws. Yes sure. Part 3 is ready. Will upload soon

[@wildboy1312]

Sir you are love plz male more videos like this plz sir plz sir I love orthooo

[@zrational7882]

Is uncontrolled tipping pure rotation?

[@irfansinstituteofclinicalortho]

Yes. As there's no couple in that

Sir majority of point's are not in proffit???

Yes they are mostly in biomechanics

In chapter of biomechanics in profit Also in nanda

I am 27 years old, My teeth is slightly project outward. Can we push upper jaw downward with teeth using braces? I have seen many videos in KZbin about pushing teeth downward with jaw, but my orthodentist telling, it is impossible to move upper jaw downward with brace, Is it true or not?

[@irfansinstituteofclinicalortho]

Well. Can't say without examination... downward movement of jaw is not possible but movement of teeth possible in all directions

[@lifeworld925]

@@irfansinstituteofclinicalortho Thank you for the valuable reply sir, My upper and lower teeths are slightly project outward. My upper jaw having slight outward projection. Now I am 27 years old. I have a doubt, If we move the upper front teeth downward then is there a chance of movement of upper jaw downwards? I have consulted some orthodentist, some of them told, It is impossible to move down the upper jaw with teeth using braces, only possiblity is jaw surgery. But few orthodentist told me, they are using expensive braces, so they can move upper jaw downward with teeth using braces. Is it possible? Now I am totally confused. Please clarify my doubt sir🙏🙏
