The MDA, Multi Distalizing Arch, is a fixed appliance for distalizing molars. This course shows how the appliance can be used for both the maxilla and mandible as needed with the non distalizing arch used for anchorage. It can be used on adolescents or adults as well as non compliant patients. The mechanics for the MDA are quite simple and easy to perform. There are dozens of appliances for distalization but we prefer to use the MDA for several reasons. It is rare that both sides will require the same amount of distalization and this appliance allows unilateral and bilateral distalization, even different amounts per side during bilateral use. We will demonstrate the technique for doubling the anchorage on the distalized arch which reduces the amount of compliance required. We will also introduce interarch springs that can be ligated in placed in the event of total non compliance. With good compliance, you will see a translation of all the posterior teeth which significantly reduces the time spent with finishing mechanics and we will show how to mechanically retract the teeth during distalization if the teeth are not translating.

We will show the technique and demonstrate how to adapt the MDA for initial seating, initial activation, seating and ligation procedures and periodic adjustments. For clinical application, you will see a completed case presentation of the MDA for correction of a class II dental case from beginning to retention.

This is a wonderful overview of an appliance that allows for AP correction of molars without the use of headgear. This allows for a lot more cases to be treated to Class 1, and without extractions. This appliance has been a blessing to the ortho side of my practice.
