MARA Appliance in Springfield, OR: A Practical Guide
The MARA appliance in Springfield, Oregon, is a fixed orthodontic device used to correct Class II bites by encouraging the lower jaw to posture forward. At Epperson Orthodontics, this page explains how the appliance works, who may benefit, and what patients can expect from start to finish.
MARA Appliance Explained
The MARA Appliance, short for Mandibular Anterior Repositioning Appliance, is a fixed functional appliance that helps align the jaws and reduce an overjet. It is most often recommended for growing patients with Class II malocclusion, where the upper teeth and jaw sit ahead of the lower jaw. By guiding the lower jaw forward during growth, it can improve bite function and facial balance while reducing the risk of upper front tooth injuries.
Unlike removable devices or rubber band wear alone, the MARA is attached to the teeth, so it works full time. It may be used on its own or alongside braces or clear aligners to improve both bite and tooth alignment.
Benefits of MARA Treatment
- Continuous correction because the appliance is fixed and works around the clock.
- Improved jaw relationship that can reduce a prominent overjet and enhance facial profile.
- Lower reliance on patient compliance compared with removable appliances.
- Potential to reduce the need for extractions or jaw surgery in selected growing patients.
- Protection benefits by decreasing trauma risk to protruding upper front teeth.
- Compatibility with braces or aligners to coordinate bite and tooth alignment.
How the MARA Appliance Works
Placement And Activation
Treatment begins with an orthodontic evaluation, dental records, and a bite analysis. The MARA is typically anchored to the first molars with crowns or bands on the upper and lower teeth. Metal components called “elbows” or “arms” guide the jaw forward when the mouth closes. Small adjustments move the lower jaw into a healthier position over time.
Treatment Timeline
Active wear often ranges from 9 to 15 months, depending on growth, bite severity, and cooperation with good hygiene. The MARA may be followed by braces or clear aligners, or used in combination with them, to fine‑tune tooth positions after the bite is improved.
What to Expect During Treatment
Comfort And Speech
Mild pressure or soreness is common during the first week and after adjustments, similar to braces. Speaking may feel different for a few days while the tongue adapts, and most patients adjust quickly.
Eating And Diet
Choosing softer foods at first can help with comfort. To avoid damage, patients should skip hard, sticky, or chewy foods such as nuts, ice, caramel, and taffy. Cutting food into smaller pieces makes eating easier and protects the appliance.
Oral Hygiene
Thorough brushing is essential, especially around bands and elbows. A soft toothbrush, interdental brushes, and a fluoride rinse can help keep plaque away. Daily flossing with a floss threader is recommended, and professional cleanings should stay on schedule.
Activity And Protection
Most sports and musical activities can continue. A properly fitted mouth guard is recommended for contact sports to protect both the appliance and teeth. If a part loosens or irritates the cheek, orthodontic wax can provide relief until a repair visit.
Who Is a Candidate And What Are the Alternatives?
The MARA works best for patients who are still growing and have a Class II bite due to a retrusive lower jaw. Individuals with limited growth remaining, significant skeletal discrepancies, or complex bite concerns may need alternative approaches. Options can include elastics, other fixed functional devices such as a Herbst or Forsus appliance, or orthognathic surgery in adult cases. An in‑person evaluation helps determine whether the MARA fits your goals and timing.
Key Takeaway: The MARA Appliance addresses the jaw position rather than only the teeth, making it a powerful tool for correcting Class II malocclusion during growth.
