From: Different biomechanical effects of clear aligners in bimaxillary space closure under two strong anchorages: finite element analysis

Fig. 1

Models for the finite element analysis. A The bimaxillary tissues were generated according to patient data, and the clear aligners, attachments, miniscrew, and buccal button were constructed based on available products. B The assembled research model in different views. C Three groups of different anchorage were constructed: the moderate anchorage group was used as a control group to the two strong anchorage groups. Indirect strong anchorage group: the second premolars and miniscrew were ligated together with metallic ligation wire. Direct strong anchorage group: the elastic force was applied to the canine region of the CA with the assistance of miniscrews
