Headgear

Headgear is often used to correct an excessive overbite. This is done by placing pressure against the upper teeth and jaw, which would hold the teeth in position or help move them into better positions. The severity of the problem determines the length of time headgear needs to be worn. The key to success with your headgear appliance is consistency. Headgear must be worn a certain number of hours per day, and if not, it must be made up the following day.

Headgear should never be worn while playing sports and should also be removed while eating or brushing your teeth.

MARA

The Mandibular Anterior Repositioning Appliance (MARA) is suitable for treating class II malocclusions, which are characterized by 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. Using MARA, class II malocclusions are treated more effectively. The MARA is reliable and reduces treatment time.

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. Also, the orthodontist can more accurately predict the length of treatment.

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

Sore spots are minimal. Initially, it may feel strange to hold your jaw forward while eating, but within two weeks, chewing will become more natural. We recommend you eat soft foods initially. Do not chew on the elbows. Avoiding candy, hard foods, etc. throughout treatment will help prevent breakage of the appliance.

MARA is generally worn between 15 to 18 months. Your improvements will be noticed immediately!

Rapid Palatal Expander

Attached to the upper molars through bonding or by cemented bands, the Rapid Palatal Expander is an orthodontic device used to create a wider space in the upper jaw. It is typically used when the upper jaw is too narrow for the lower jaw or when the upper teeth are crowded or blocked out of the dental arch.

When patients are still growing, their connective tissue between the left and right halves of their upper jaw is very responsive to expansion. By simply activating the expander through turning a screw in the center, with a special key we provide, gradual outward pressure is placed on the left and right halves of the upper jaw. This pressure causes an increased amount of bone to grow between the right and left halves of the jaw, ultimately resulting in an increased width.

Forsus Appliance

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. It is important to keep the appliance clean; you may do this by carefully brushing the coil and other metal pieces of the appliance. Also, we recommend that patients not open their mouths very wide, as the appliance may come apart.

If your Forsus appliance breaks, please contact our office immediately to schedule a repair appointment.

Distal Jet Appliance

The Distal Jet Appliance is a non-removable lingual appliance that is used to move upper teeth backward faster and more predictably than headgear. The Distal Jet distalizes molars and corrects teeth that have rotated. This appliance corrects class II problems.

The Distal Jet Appliance uses a solid track wire and two sets of locking screws on each side. The appliance is self-limiting by design because it has a distal stop attached to the tracking wire. The Distal Jet can be converted to a Nance Appliance by tightening the distal and anterior locks against the track wire and adding a Nance holding arch.

Thumb/Finger Appliance

Sucking is a natural reflex that relaxes and comforts babies and toddlers. Children usually cease thumb sucking when the permanent front teeth are ready to erupt. Typically, children stop between the ages of 2 and 4 years. Thumb sucking that persists beyond the eruption of primary teeth can cause improper growth of the mouth and misalignment of the teeth. If you notice prolonged and/or vigorous thumb sucking behavior in your child, talk to your dentist.

One solution to thumb sucking is an appliance called a "fixed palatal crib." This appliance is put on the child's upper teeth by an orthodontist. It’s placed behind on the upper teeth on the roof of the mouth. The crib consists of semicircular stainless steel wires that are fastened to molars using steel bands. The stainless steel wires fit behind the child's upper front teeth, and they are barely visible. The crib usually stops the habit of thumb sucking within the first day of use, but must be worn for several months so the habit doesn't return.
