MARA

The MARA appliance is a Class II corrector anchored on crowns on the upper and lower first molars, often our ROC crowns. Made to your Rx and shipped in 10 business days or faster.

Class II Correction

MARA

Removable upper elbows on the first molar crowns meet lower shoulders, so the patient can only close with the mandible forward. You advance it with shims or by adjusting the upper elbow. Hooks soldered to the upper crown and elbow, tied with a ligature, hold the elbow to the crown.

When it’s the right call.

Use it when
Class II correction in a patient who won't wear elastics
Doctors who prefer no rods, tubes or telescopes
Stepwise advancement you control chairside with shims
Cases where an upper expander runs at the same time
Consider another appliance when
You prefer a telescoping Herbst for continuous mandibular advancement See Specialty Miniscope® Herbst
The case needs extra opening and lateral range See Specialty M4® Herbst
Compliance is reliable and you'd rather use a removable functional appliance See McNamara Twin Block

Options you can prescribe.

Anchorage

Choose bands, ROC crowns, crowns or OnBRACE®. Note OnBRACE® on the Rx.

Upper expansion

Add a 12 mm RPE screw, a mini-expander or a click screw.

Lower lingual arch

Included without loops. Add loops if you want them.

Add-ons

Add a TPA, quad helix, occlusal rests, archwire tubes or lingual seating lugs.

Still deciding which Class II corrector?

Fixed or removable, telescoping or not, and how much you want to depend on the patient. Those three choices narrow most Class II cases to one appliance.

FAQ

Questions about the MARA.

Ours is a fixed Class II corrector on crowns on the upper and lower first molars, where upper elbows meet lower shoulders to hold the mandible forward.

The MARA uses crown-mounted elbows and shoulders instead of a telescoping rod and tube. For the trade-offs in a specific case, talk to a clinical expert before you prescribe.

Our ROC crowns have the occlusal surface removed, which makes relocation easier. They're a popular anchorage choice for the MARA.

Yes. We add brackets or archwire tubes on request, and the MARA is often built with an upper 12 mm RPE screw.
