The Multi-Distalizing Arch (MDA) Appliance is a true multi-treatment device which reduces treatment time and cost, while improving patient comfort and cooperation.

The MDA can be used for the following:

• Bilateral, maxillary, or mandibular distalization
• Correction of asymmetrical malocclusions
• Retracting and intruding maxillary and anterior teeth
• Mixed dentition cases because the appliance is not phase dependent
