Treatment of Skeletal Open Bite With Open Bite Activator and Skeletal Anchorage-Supported Vertical Elastics

Participants received a removable open bite activator constructed with the mandible opened beyond the freeway space and combined with vertical intermaxillary elastics applying 150g of force, supported by mini-screws placed between the lateral and canine teeth in both the maxilla and mandible. The appliance was worn 20-22 hours daily for 12 months. This approach aimed to treat skeletal open bite without using extraoral appliances by promoting anterior mandibular rotation and inhibiting posterior vertical dentoalveolar development.
