Herbst appliance versus Mara appliance
Herbst appliance and the Mara appliance are both in use by orthodontists across the country, so why one over the other? Personal preference of the orthodontist to a large extent. The Mara appliance is slightly smaller but both are large enough that they take some time for a patient to adjust to. The Mara appliance, being smaller, has more complications, like breaking. We almost exclusively utilize Herbst appliances over the mara appliance.
Why the Herbst appliance over the Mara appliance?
One of the most common problems presented to an orthodontist is the upper teeth being further forward relative to the lower teeth. In most cases, this is the result of the lower jaw being set back relative to the upper jaw, as opposed to the upper jaw being too far out.
Traditionally headgear would be used to correct this issue. The Herbst appliance accomplishes the same thing and is actually more effective. While it has the same “headgear effect” of holding the top jaw from continuing to outgrow the bottom jaw, it also pushes the bottom jaw forward, helping it “catch up”. The growth center of the bottom jaw is near the lower jaw joint and the Herbst appliance works to “remodel” this area. Additionally, the Herbst appliance is a great “tooth mover”, helping to move the lower teeth move forward. An orthodontist will cement the Herbst in place, so it cannot be removed by the patient and does not rely on patient compliance.
By utilizing the Herbst while your child is growing, we can maximize their growth potential and eliminate the need for a jaw advancement surgery to fix the bite later in life. Although positive esthetic changes to the jaw line and face will occur, the purpose of correcting their bite is not just for cosmetics. It is important to have a proper bite where the teeth can work efficiently to aid in digestion and avoid future issues with the teeth and jaw muscles.
