The 3-way screw is designed for both widening and lengthening the arch, with the anterior section directing forces forward via the incisors. An alternative design uses three distinct screws: one for widening and two in the sagittal plane for posterior distalization. For optimal retention, Adams clasps on the 6’s (if present) and ball clasps between premolars are recommended. Additional features include a labial bow for anterior control and a posterior bite plate, bolstering anchorage for the upper appliance.

The Hawley Retainer, equipped with soldered Adams clasps, primarily ensures the retention of anterior teeth. The labial bow offers this retention without any interproximal wire interference with the front teeth.

For optimal results, wear the appliance for 22 hours daily and clean with toothpaste to prevent plaque and odor. Steer clear of effervescent solutions like Efferdent, which might erode appliance components. Instead, consider using DentaSoak or Retainer Splash for maintenance.
