  Hi doctor. Why do you make two tear loops in different size ? Does it have any special reason? Thank you.

• 
  @essentialbiomechanics9381Ай бұрын

  the tear-drop loop is to reduce the load-deflection rate and the omega loop is an auxiliary that can be used to activate the appliance. Instead of activating from the distal (as in the video), you can tie a ligature wire from the molar to the omega as a second way of activation.

  Dear doctor, I have ordered and read your book. I’m confused about 6 geometries. Can rectangular loop and root spring create geometries I,II,III ? or just IV,V,VI?

• 
  @essentialbiomechanics9381Ай бұрын

  It's not impossible....but if we focus on ONE unit (the active unit that we want to move), and you draw the desired forces for this unit, you'll see that the forces needed to achieve equilibrium will always result in a geometry V, V or VI (considering the diagram of force system of our two-tooth segment.

  If the molars have different tip inclinations, does the activation have to be different to avoid anterior cant? Could it be useful to make two separate cantilevers?

  How can we know if only moments are acting in trial activation?

• 
  @essentialbiomechanics9381Ай бұрын

  In the trial activation, we apply gentle couples (as shown in the video)....and then you check if the parallelism between the appliance and the tube occur exactly at the tube level - in this case, there will be only moments acting. If during trial activation you observe that the parallelism occur when the appliance is below the tube, there will be an intrusive force on this unit. On the other hand, if the parallelism occur when the appliance is above the tube, there will be an extrusive force on this unit.

  200 g is enough for retraction of the anterior group of teeth

  Aren't we retracting the whole arch as we are applying force on the wire. . How much force would be enough for the arch Sir. 200?

• 
  @essentialbiomechanics9381Ай бұрын

  Sorry, now I got your question. The answer is the same - yes, 200 g is enough even for the entire distalization of upper arch. It may seems strange that we can use this same magnitude for different purposes, but it's true. Literature has shown that around 200gm is enough even for distalization of the entire amndibular dentition - Roberts WE, Viecilli RF, Chang C, Katona TR, Paydar NH.

  by the application of a lingual force, in combination with the intrusive force. Therefore, note that I'm applying TWO forces simultaneously - the intrusive force (2nd order preactivation) + the lingual force (1st order preactivation).

  Mesial tipping?

• 
  @essentialbiomechanics93813 ай бұрын

  The aim was to produce a translational movement. Some tipping occured because I exaggerated the reactivation in this simulation. Clinically, I prefer to already add bends (gable effect) to minimize the final molar angulation problem. If necessary, it's also possible to make the bends and cinch the teeth for later correction.

  Cómo va a mesializar con el mini implante dentó alveolar? No estorbará al mesializar?

• 
  @essentialbiomechanics93812 ай бұрын

  Hola Dra. Las fuerzas y momentos percibidos por el mini-implante pueden ser soportados sin problemas, siempre y cuando en este caso (lado inferior izquierdo, por ejemplo) utilices un tornillo de rosca izquierda. Esto se debe a que, al aplicar algunas dobleces gable (no demostradas en el video), el tornillo recibirá un momento antihorario, mientras que el molar recibirá un momento horario para minimizar la inclinación hacia mesial. Gracias por la excelente pregunta y la oportunidad de aclarar este punto.

  Yes, this is one variable that indicate the patient does not have strong muscles. But I'd not be afraid of posterior intrusion, because the splint is not used for a significant amount of time.

  In this case NO Dr, because this would act as a cantilever - and vertical forces would be produced. You need a statically indeterminate system (fully attached in both ends) in order to produce only couples (Geometry VI system)
