MARA stands for Mandibular Anterior Repositioning Appliance. It is a non-removable appliance that encourages the growth of the lower jaw to help correct severe overbites and minimize the need for extractions or orthognathic surgery.
The MARA appliance is anchored to the molars with crowns, modified crowns, or bands. The lower attachments are fixed to the molars. The upper attachments are removable to enable your orthodontist to make adjustments according to your treatment plan.
