In vitro comparison of the effects of direct attachment shape and location on forces and moments generated by thermoplastic aligners during simulated torque movement
Changing attachment shape and location had a significant effect on the forces and moments generated during simulated maxillary incisor torque. The best design for the incisor torque movement was found to be the horizontal ellipsoid attachment at the middle third. Besides the desired torque moment, all attachment shape and location combinations produced a vertical extrusive force as a side effect.
