    Lower Sagittal Appliance

    The Sagittal Appliance is tailored to lengthen the arch, either by moving molars backward or pushing the anterior section forward, effectively addressing crowding. It features expansion screws aligned with the sagittal plane, with optional screws on each side. For optimal retention, Adams clasps on the 6’s (if present) and ball clasps between premolars are advised. Additional features include a labial bow for anterior control and a posterior bite plate, enhancing anchorage for the upper appliance.

    T-REX APPLIANCE

    The T-Rex Appliance offers a two-phase approach: arch expansion followed by molar distalization. It employs a pre-activated .032 TMA wire, an expansion screw, and premolar rests. During expansion, a wire embedded in acrylic halts spring activation. Once arch development concludes, clinicians cut this wire, activating springs for molar distalization. An adjustment loop can assist molar rotation, and lingual sheaths, provided by the lab, are spot-welded onto the band.

    Transverse Appliance

    The Transverse Appliance effectively widens both upper and lower arches, addressing bilateral crossbites and anterior crowding. Given the force from the screw, robust clasping is advised. For optimal retention, we recommend Adams clasps on the 6’s (if present) and ball clasps between premolars. Additional features include a labial bow for anterior incisor control and a posterior bite plate, enhancing anchorage for the upper appliance.
