Functional Appliances: Mara® Appliance
The Mandibular Anterior Repositioning Appliance (MARA) is used for achieving Class II correction treatment goals. The newer fixed design increases patient comfort by eliminating appliance bulk and tissue irritation in the lower bicuspid area that can occur with other fixed functionals.
Functional Appliances: Mara® “U” Appliance
To enhance the effectiveness of the Mara Appliance in very deep overbite cases the U-Mara is an excellent alternative. In deep overbite cases when the mandible is advanced there is a large posterior open bite making it difficult for the patient to keep the upper elbow and lower loop properly engaged. The “U” modification addresses this problem by reversing the lower loop to provide additional millimeters of vertical engagement between the lower arm and upper elbow.
