Initial force systems during bodily tooth movement with plastic aligners and composite attachments: A three-dimensional finite element analysis.

Conclusions: In a three-dimensional FE analysis of a plastic aligner system biomechanically supplementary composite attachments generate the force system required to produce bodily tooth movement; the absence of biomechanically supplementary composite attachments favors the undesired inclination of the tooth during the translation movements.
