Assessment of Maxillary Molar Tooth Changes Caused by Class III Elastics in Hybrid Hyrax-Mentoplate Treatments: A Pilot Study

The use of Class III elastics causes greater expansion at the apical level than the coronal. Molar teeth exhibit a mesial movement, but there could be multiple contributing factors. In molars connected to Class III elastics, extrusion occurs. When vertical control is important, appropriate safety measures are advised.
