Distalization, Fixed Appliances

T-Rex Appliance

The T-Rex Appliance is used to distalize the molars and expand the arch in two phases. Effective arch development is achieved with pre-activated .032 TMA wire, an expansion screw, and rests on the premolars. After expansion, it produces a wide swinging arc of force from the midline of the palate to the upper molars producing a pendulum motion of the spring. A wire is welded to the band and embedded in the acrylic preventing the activation of the springs while expansion is occurring. When transverse arch development is complete, the clinician cuts the welded wire causing the springs to activate and distalize the molars. An adjustment loop can be added to the spring to aid in rotation of the molars. Lingual sheaths are spot welded onto the band and can be provided by the lab.

Treatment & Care

The typical rate of activation is one (1) 1⁄4 turn every three days. Most screws we use in mid-palate applications require five (5) activations per 1mm.

This appliance is delivered from ODL with springs pre-activated. Use an elastic o-ring to hold the spring to the band. The patient should be seen every three weeks, and reactivation should be done if needed by holding the center of the helix with a bird beak plier and push the spring distally.

This appliance should be cleaned every day with toothpaste and a soft toothbrush, morning and night. Encourage the patient to give sufficient time to clean thoroughly around the appliance, gums, teeth, and bands to maintain proper hygiene and prevent inflammation. 3 minutes is recommended.
