Orthodontic Appliances


A metal wire which is attached to your brackets to move your teeth.


A metal ring that is usually placed on your teeth to hold on parts of your braces.


Brackets are the small metal or ceramic modules attached to each tooth. They serve as guides to move the teeth and hold the archwire in place.

Buccal Tube

A small metal part that is welded on the outside of a molar band. The buccal tube is a slot to hold archwires, lip bumpers, facebows and other things your orthodontist uses to move your teeth.

Clear Shell Retainer

Clear retainers that are utilized to hold teeth in position similar to that of a traditional retainer. They are less visible than traditional wire and acrylic retainers.


A stretchable plastic chain used to hold archwires into brackets and to move teeth.


Elastics or rubber bands help move the upper and lower teeth relative to each other, ultimately achieving a better bite. These orthodontic rubber bands are typically effective for correcting overbites, underbites, or other types of alignments of the jaw. They are also useful for moving a tooth out of alignment or to close a space in the mouth.

Elastic Tie

A small plastic piece, shaped like a donut, which is used to hold the archwires in the brackets on your teeth.

Fixed Retainers

Fixed retainers consist of a metal wire bonded to the back of the teeth. Fixed retainers can stay in place indefinitely.


A forsus appliance is used to correct a class II bite by pushing the lower teeth forward and the upper teeth backward. Unlike rubber bands, this appliance is not removable.

Habit Appliance

This simple device given to address severe thumb/finger sucking habit. It involves using a wire crib attached to two back braces.

Hawley Retainer

An appliance that the orthodontist gives you to wear after your braces are removed. The retainer fits over your upper and / or lower teeth and holds them in the correct position while the bone around your teeth stabilizes. At first, you wear the retainer 24 hours a day, and then only at night.

Herbst Appliance

An Herbst appliance is a fixed appliance with pistons and bands which are cemented to the back teeth. Pistons force the lower jaw forward retraining the bite in cases where upper molars are in a position forward of the lower molars, thus correcting a Class II problem.


Invisalign® is a series of clear, removable teeth aligners that are used as an alternative to traditional metal dental braces.

Lingual Arch

A lingual arch is an orthodontic device which connects two molars in the upper or lower dental arch.


A device that is used to protect your mouth from injury when you are participating in sports. The use of a mouthguard is especially important for orthodontic patients, to prevent injuries.


The Nance button is utilized to hold the upper molar teeth in position while allowing for the movement of other teeth. The impact of the button on the lower palate creates a force on the back molars.

Palatal Expander

A palatal expander, also known as a rapid palatal expander, rapid maxillary expansion appliance, palate expander or orthodontic expander, is used to widen the upper jaw so that the upper and lower teeth will fit together better.

Quad Helix

A Quad Helix (or quadhelix) is an orthodontic appliance for the upper teeth that is cemented in the mouth. It is attached to the molars by 2 bands and has two or four active helix springs that widen the arch of the mouth to make room for crowded teeth, or correct a posterior cross-bite, where lower teeth are buccal (outer) to the upper teeth.


A functional appliance used to expand the upper or lower dental arches. It is adjusted daily as instructed until the arch has been widened enough, and is then left in place for a period of time to allow for stabilization of the widened arch.


Separators are tiny rubber bands or springs that your orthodontist places between your back teeth. These separators prepare your mouth for braces by creating a small gap between these teeth. This space allows for the placement of a metal band around your molar, which anchors your braces in your mouth.

Spring Aligner

An appliance that can be used on both arches for minor rotation and correction of anterior alignment.

Transpalatal Bar

The Transpalatal Bar (TPA) is a fixed appliance that is attached to bands on the upper molar teeth. The bar sits across the roof of the palate and fits into a soldered clip located on the bands.
