Appliances

Expanders

Expanders are appliances that are commonly used to correct cross-bites and narrow jaw forms. Comprised of anchors and a piece spanning the roof of the mouth between, an expander works by applying outward pressure on the bone and teeth of the upper jaw. 
 
The human skull at birth is like a puzzle; pieces of fully formed hard bone are joined by softer connective tissue. One of these fissures is located at the roof of the mouth. By exerting outward pressure on this seam in the bone, a gap is created which the  body natrually fills in with new bone. This creates a wider upper jaw.
 
To activate the device, you simply turn the screw a very small amount each day with a special key. Once the desired expansion is achieved, we will replace the expander with a holding appliance.

Forsus

The Forsus appliance is used in order to help move the upper molars back while moving the lower arch forward. Composed of a spring coil rod, the appliance is used while a patient is currently wearing braces. It runs from the upper first molar band down to the lower archwire.

You may notice some discomfort initially, so we recommend a soft food diet for the first few days after the appliance is placed. Regular anti-inflammatory medication may help with any pain, if needed.

MARA

The Mandibular Anterior Repositioning Appliance (MARA) is suitable for treating protrusion of the upper front teeth or a lower jaw and/or teeth that are positioned back in regard to the upper jaw and/or teeth. Generally, the appliance is secured to the patient’s first molars via stainless steel crowns, which are easy to fit and retain more, compared to bands. The appliance features no removable parts, which means patient compliance is not an issue.

The upper “elbows” can be removed; which facilitates comfort and advanced adjustments. The appliance can be advanced on one side or both sides. 

Herbst

The Herbst appliance prevents the lower jaw from moving backward but allows opening and closing movement to occur easily. At first, your mouth will feel unusually full, and speaking will be awkward. But if you practice reading aloud, your ordinary speech will return quickly. You may also notice more saliva than normal, but this will decrease as you become accustomed to the appliance. Patients will not have any problems learning to chew their food with their lower jaw in this new position. As with all kinds of braces, patients with Herbst appliances need to be careful about what they eat. Your Herbst appliance will be checked and adjusted at your appointments. If, sometimes between appointments, you develop some sore areas on the inside of your cheeks, please do not try to adjust the appliance yourself. Call for an appointment so that the necessary adjustments can be made.
