Understanding the Mechanics of the MDA Appliance

Understanding the Mechanics of the MDA Appliance is organized by Dentaltown, L.L.C.

Overview:
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.
Educational Objectives:
Upon completion of this course, participants should be able to achieve the following:
• Select the proper size appliance
• Adapt the appliance to the individual patient
• Activate, adjust and manage the molar distalization
• Learn the requirements for use, case selection criteria, and post appliance procedures for case completion.
Note: The fee to view this course is $36. This cost includes the fee to take the exam and claim your CE credits.
