- A real possibility to have a fast orthodontics consists in achieving precise dental movements, without significant side effects. The use of an activated transpalatal bar to derotate molars is a great example of efficiency. Watch on this video how a TPA symmetrically activated can work to derotate first molars.

Wow ..what a good Demonstration...thanks a lot
I have this device and at first I couldn't speak or eat for almost 2 weeks not to mention the excruciating pain. Courage.
I had this and I was annoying to wake up with dents in your tongue and S & Sh sounds sounded weird but other than that I didn’t have to deal with a lot of pain. Only when the orthodontist rotated the one molar that was stubborn in office I heard a crack in my head. But it’s all good now. I am still in braces and the bar is removed so I enjoy freedom of speech 😂
What wire material used for This TPA?
SS or TMA ? Also size used ? 0.9 mm? @essential biomechanics
thanks
Very good sir. but right now I am treating a patient of cleft lip and palate. she also has hypodontia and only hv 6 teeth in upper arch and left maxillary 1st molar is rotated distopalataly hindering the eruption of 2nd molar and she has no premolars. How to design TPA for this purpose? If you can give some advice.
Great video, I'm planning to use one for the first time, from the Wilson3D system. Do you know how long would it take to achieve molar derotation like the one presented in this case?
Dear Adri, I apologize I didnt see your message. I think the movements illustrated in the video would take around 3 months to occur. We know that the velocity of tooth movement depends on a lot of variables in the clinical practice. But I´m sure this molar derotation is usually very efficient using this activation.
Why don't you approach ant side but post side( thatS thorat side)
very good documentation can you please tell me what is the program used to determine the pressure areas on the root...thank u so much

Hello sir, may I ask what molar band you used? As there's no need for soldering on the ones you posted. Thanks!
Excelente!
From where could i get these teeth & model
Can this correct by alignmeny only by sequence of arch wire
Sir actually my TPA is solder with my molar band and my buccal tube is kept out from band nd my molar band is also start lossing . my orthodontist suggest me that if brake TPA so they have to start the treatment from beginning again.is It true ?? Please suggest me something so my molar are not lossing ...??
Sometimes its necessary to change the band by a smaller one in order to avoid loosenig the appliance.
Sir.. Which pliers u r used?
Lingual Arch Forming Plier (usually number 410): essential for effective confecction of the appliances; and Weingart plier for wire handling.
can the transpalatal arch expand the upper jaw ?
For sure. But the effect is basically dentoalveolar. Please take a look at the video in which we demonstrate this activation. th-cam.com/video/tahzpj1ZjRM/w-d-xo.html
What does derotation do in the case of an overbite
Dear Mosey, I think the molars derotation does not have a specific effect on overbite. However, if the overbite is associated with a dental class II malocclusion, the molar derotation will be very helpful in the correction of the molar relationship and the transpalatal bar will also help in the establishment and maintenance of transversal dimension.
Hi ,how to activate sold transpalatal arch.
thank you
Dear Kankouna, I think the only way to properly activate the TPA is outside the mouth. If you use the sold one, you´ll have to activate it before the cementation. It´s possible to remove, activate and insert it again. However, I strongly recomend the use of the removable one, specially because you have more accurate checking of the activations.
don't use the soldered one removal TPA can control better ,
Wat ab upper jaw teeth position
what if I have to derotate only one molar? on only one side, the controlateral is ok. thank you
Dear Andrea, you have to use this same activation, because it is the only one capable to deliver pure moments. To avoid the movement of the contralateral side, you can join the opposite molar to a rigid archwire (from this molar to the contralateral premolar), and keep your active unit-the rotated molar- conected only to the TPA. With this approach, only the rotated molar will move. I hope this tip can help you. Regards!
