Abstract:

Objective: Evaluate the effect of resin attachments on the displacement and deformation pattern of the aligner plastic, determine the center of rotation and stress distribution in the upper canine during space closure using the finite element method (FEM). Furthermore, evaluate the plastic Aligner deforma t ion. Method: A CAD model of the superior right hemiarch was constructed with the simulation of a first premo lar extraction and a canine distalization, recreating the periodontal ligament and alveolar bone. Finite element models were created to analyze the beha vior of stress and displacement of the upper right canine with aligners in 4 situations, one without at tachment and 3 with bonded attachments (vertical rectangular, rectangular beveled, optimized root control). In addition, the plastic deformation of the aligner was evaluated. Results: In the simulation without attachment the re was no apical movement, while with vertical rec tangular and rectangular beveled the behavior was similar with crown distal displacement and mesial apex displacement. The optimized attachment had a better movement control of the canine body res pecting the crown and apical movement towards the same direction. The mayor plastic deformation was shown without attachment and no deformation was evidenced with optimized attachment. Conclusion: The FEM showed that, nevertheless the optimized attachment produced a distal crown and apical displacement with the use of plastic aligners during the space closure, the apex only moved ¼ of the distal crown movement. Our results, suggest that to obtain a pure translation of the canine with alig ners it would be necessary the use of auxiliars which complement the needed biomechanics.
