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.

These wireless appliances are ideal for enduring retention after traditional or aligner-based orthodontic procedures, offering a seamless blend of discretion and effectiveness.

The primary function of the Lower Continuous Full Labial Retainer is to provide retention of the anterior teeth. Retention is provided by a labial 3 x 3 labial bow.

The Hawley Retainer, equipped with soldered Adams clasps, primarily ensures the retention of anterior teeth.
