Types of Appliances

palatal expander

Palatal Expander

The palatal expander "expands" (or widens) your upper jaw by putting gentle pressure on your upper molars each time an adjustment is made. Your orthodontist will instruct you about when and how to adjust your expander. When you achieve the desired expansion, you will wear the appliance for a few months to solidify the expansion and to prevent regression.

twin block

Twin Block

The twin block is an early intervention appliance designed to manipulate lower jaw growth in a downwards and forward manner. Full-time wear of this appliance can improve the bite and reduce the possibility of the need for jaw surgery and/or extensive orthodontic treatment in the future.

distal jet

Distal Jet

The distal jet appliance improves the molar bite relationship. It applies a gentle force on the molars. It is commonly used as a modern alternative to cervical headgear.

carriere motion

Carriere Motion II and III

The Carriere Motion appliance applies a gentle force on the canines and molars using rubber bands. This appliance improves the relationship of the bite. These appliances are used to correct Class II and Class III Malocclusions (overjets and underbites). Treatment with a Carriere motion appliance can reduce the possibility of extractions and jaw surgery in the future.



Retainers may be removable or fixed. They hold your teeth in their new, correct positions after your teeth have been straightened. Your orthodontist will instruct you on how to care for your retainer and about the duration of the wear. Wearing your retainer as directed is crucial to prevent regression of your treatment.


Elastics can be used with Invisalign, braces, or other appliances. They improve the bite relationship. Compliance is an important aspect of elastic wear. When elastics are worn as instructed treatment length can stay on track or even be shortened. Elastic can be colored or clear.


Separators are little rubber doughnuts that may be placed between your teeth to push them apart so that orthodontic bands may be placed during your next appointment. The separators will be removed before we place the bands. Separators do not stay in well when eating sticky foods or flossing.
