In this video, we look at the different types of orthodontic tooth movement, as well as forces, moments, couples, and a lot more!

Thank you! This is helping me study for my Orthodontics II college exam! The exam is in September, but I am already studying, because it's a lot of stuff

Wow!!! I cannot believe I'm understanding this. Using the pen is such a good idea.

Hi! Thank you for the video. I have a question for uncontrolled tipping: isn't the center of rotation just apical to center of resistance and not directly AT the center of resistance? Wouldn't that be a pure rotation if the center of rotation is located at the center of resistance? Thanks in advance!

@UmerFarooq-ub3li 4 жыл бұрын

No, the center of rotation can be at the center of rotation or can be apical to it or even can be at infinity. Pure rotation only takes place when forces of equal magnitude are acting in opposite directions on two opposite sides (e.g. lingual & buccal) . In rotation tooth turns around its own axis. Its not the case in tipping.

Thank you for uploading this video ! This is really great explanation and I will follow other video from the channel. Thank you much :))))

Thank you Ryan this lecture is great. I only wanted to point out that for the movement you mention at 3:40 we have two points here one center of resistance that is more coronal than the other center of rotation. As the point of force application moves towards the center of resistance the point of center of rotation moves in apical direction until the point of force application and point of center of resistance coincide then the point of center of rotation reaches infinity and as the point of force application moves in coronal direction and away from center of resistance the center of rotation moves towards the center of resistance until the time that center of force application reaches infinity that both centers of resistance and rotation coincide

Yes, you are correct! Thank you for pointing this out. I am currently working on an updated Orthodontics series, and these updates will be included.

Hi Dr. What's up? What do you prefer for traction of a canine distally, for example in CL 2 occlusion ..round SS wire or rectangular? and for retraction of ant. teeth as well. thank you so much 🌺🌺

@mentaldental 2 жыл бұрын

Hello! That is a very difficult question to answer because it really depends on a case-by-case basis. I prefer a SS round wire in most cases for reduced friction during sliding mechanics, but I prefer a rectangular TMA or SS wire if I desire more rigidity and/or torque control.

Hi Dr. how is it going? Can we intrude a molar tooth without using any surgical interference even by using a miniscrew? because the patient is afraid of using any of these procedures to solve the problem which is skeletal ant. Open bite.. he is nearly 18 years old.. by wire bending or any other modification.. please if you can help me with the treatment plan.. God bless you..

@mentaldental 3 жыл бұрын

Anterior open bite can be challenging to treat depending on the severity of the malocclusion. If it is very minor, theoretically a combination of incisor extrusion and molar intrusion with clear aligner therapy could be possible, but stability may be an issue if the patient is already done growing. TADs to intrude the upper molars is more predictable, but is technique sensitive and requires a good understanding of biomechanics.

But the centre of rotation in case of uncontrolled tipping is located between centre of resistance and root apex

@mentaldental 4 жыл бұрын

Yes, technically you are absolutely correct. I kept it very simple in this video and while the center of rotation is very close to the center of resistance it is actually a bit towards the root apex. Thanks for pointing this out!
