Vertical growth control during maxillary expansion using a bonded Hyrax appliance

Vertical growth control during maxillary expansion using a bonded Hyrax appliance

Introduction: Rapid maxillary expansion (RME) for the treatment of maxillary deficiency and posterior crossbite may induce changes in the vertical dimension. Expanders with occlusal splints have been developed to minimize unwanted vertical effects. Objective: This preliminary study used cephalometric radiographs to evaluate the vertical effects of RME using a Hyrax appliance in children with ma...

Assessment of vertical changes during maxillary expansion using quad helix or bonded rapid maxillary expander.

OBJECTIVE To determine if there is a significantly different effect on vertical changes during phase I palatal expansion treatment using a quad helix and a bonded rapid maxillary expander in growing skeletal Class I and Class II patients. MATERIALS AND METHODS This retrospective study looked at 2 treatment groups, a quad helix group and a bonded rapid maxillary expander group, before treatmen...
