Use of Pliers for Minor Tooth Movement


When a tooth does not move as desired, you can apply some extra force by creating force-generating points on the aligner to help the tooth move without having to resort to a case refinement. 

The crack resistant properties of Zendura material coupled with high tensile strength durability makes this material ideal for minor tooth movements achieved from resetting teeth on cast models or using industry standard detail/thermo-forming pliers. 0.5mm dimples are placed in Zendura appliance on the desired tooth to create a moment of force.

Rotations: Add 0.5mm dimple on desired tooth positioned near the middle 1/3. The dimple can be placed on the buccal and lingual surfaces to achieve a forced couple.

Space Closure: Add 0.5mm dimple on the facial middle 1/3 to apply force in the Zendura appliance. Some material might be removed on the lingual so the tooth has room to move.

Retainer Retention: Add 0.5mm dimple at each embrasure space (buccal/lingual) to help tighten the Zendura appliance.

We do not suggest pre-heating the pliers or pre-treat the aligner/retainer in order to create a force-generating pressure point. The heat might cause the material to melt and deform, thus losing necessary force to move the teeth.

If you use other pliers such as Essix brand thermopliers and prefer heating the pliers prior to forming the dimple, please follow their instructions on choosing the correct pliers for a specific tooth movement purpose and heat the pliers up to 245 F for Zendura material. 


1.    Prepare Zendura aligners/retainers and detail/thermo-forming pliers. 



2.    Locate the desired tooth ready to create a dimple near the middle 1/3. To create a dimple (pressure point), simply orient the pliers tip over the desired tooth and gently squeeze.



3.    Place dimple on the buccal and lingual surfaces of Zendura appliance to achieve a forced couple.



4.    Dimples are created on the desired tooth to achieve moment of force.
