MDA – Mini Distalizing Appliance

The MDA is an appliance used to achieve arch development through expansion of a compact RPE and pre-activated .032 removable TMA springs. The design allows for expansion and distalization to occur in two phases. Once the proper width is complete via the screw, the clinician cuts the wire holding the pre-activated springs to begin distalization. With each expansion appliance, we provide a custom swivel key that has an integrated activation recording tool directly on the handle.
