Creating Smiles: Treatment of Class II Malocclusion With D2 Appliance

In this case report, we will review the use of the D2 appliance by Ortho Arch to correct a Class II malocclusion in combination with using a fixed removable lower lingual holding arch to provide mandibular anchorage.

The D2 Sagittal Corrector can bring your patient to the occlusal goal of a Class I occlusion in three to five months. The D2 utilizes elastics at the start or early part of treatment. The appliance consists of two parts. The appliance has a posterior component that has a free-floating metal bar attached and is first bonded to the six-year molar, and an anterior component. The posterior bar is cut to length and can be measured to fit any size span. The anterior component is bonded to an anterior tooth (in this case, the canine) after placement of the posterior bar into a reception hole in the anterior component. These components are universal and can fit both the right and left sides.

By using the D2 appliance, we can usually expect to see decreased treatment times in patients who cooperate with elastic wear as this patient did during her treatment.
