The MARA is designed to be a simple, durable Class II corrector. The appliance is generally anchored to the patient’s first molars with stainless steel crowns. The advantages of this appliance include reliability and a shortened treatment time.

The upper “elbows” may be removed by the clinician or staff, facilitating comfort and advancement adjustments. Patients adapt to the MARA in a few days and sore spots are minimal. The appliance may be advanced unilaterally or bilaterally and works well in skeletal midline asymmetry cases. Upper and lower archwire tubes are standard, allowing the clinician the option of using fixed mechanics during the MARA therapy. A lower lingual arch is also a standard element of the appliance. Other popular options include expansion screws, habit devices, transpalatal bars, crown removal holes and ligation modifications.

An accessory kit is available that includes advancement shims/spacers, extra elbows (2 sizes) and a torquing tool to aid in elbow adjustments.
