MARA (Mandibular Anterior Repositioning Appliance)
The Mandibular Anterior Repositioning Appliance (MARA) is suitable for treating class II malocclusions, which are characterized by protrusion of the upper front teeth or lower jaw and or teeth that are positioned back in regard to the upper jaw and or teeth. Using MARA, class II malocclusions are treated more effectively. The MARA is reliable and reduces treatment time. The appliance is generally used during the late mixed dentition development stage through advanced adulthood.
Generally, the appliance is secured to the patient’s first molars via stainless steel crowns, which are easy to fit and retain more, compared to bands. The appliance features no removable parts, which means patient compliance is not an issue. Also, the orthodontist can more accurately predict the length of treatment.
The upper "elbows" can be removed; which facilitates comfort and advanced adjustments. The appliance can be advanced on one or both sides.
Sore spots are minimal. Initially, it may feel strange to hold your jaw forward while eating. But within two weeks, chewing will become more natural. We recommend you eat soft foods initially. Do not chew on the elbows. Avoiding candy, hard foods, etc. throughout treatment helps prevent breakage.
MARA is generally worn between 15 to 18 months. Improvements are noticed immediately. A Lower Lingual Arch and Rapid Palatal Expander can be incorporated into the appliance.
