Types of Appliances


The upper and lower teeth fit better when you wear elastics (rubber bands). Keep in mind that rubber bands work better if they’re worn the way Dr. Nadeau instructed.


To help adolescents jaws grow properly, the Forsus Fatigue Resistant Device is an alternative to headgear. It can help reduce overbite problems, improve the fit of the teeth, and even avoid jaw surgery.


Headgear is used to treat people who have an overbite (upper jaw front of lower jaw) or an underbite (lower jaw forward of upper jaw). Headgear softly “pulls” on your teeth, preventing forward development of your top teeth and jaw.


The Herbst® device corrects overbite by pushing the lower jaw forward and the upper teeth back. This fixed device is mostly utilized for younger, growing children and is worn for around 12-15 months.


Each time an adjustment is performed, the palatal expander “expands” (or widens) your top jaw by applying slight pressure to your upper molars. When and how to alter your expander will be explained to you by your orthodontist. When you have achieved the desired enlargement, you will wear the appliance for many months to firm it and avoid relapse.


Positioners complete the last tooth movements, bringing your orthodontic treatment to a finish. If you comply entirely, you should only need to use the positioner appliance for four to eight weeks.


Retainers may be removable or permanent. They maintain your teeth’s new, appropriate positions once they’ve been straightened. Your orthodontist will instruct you on how to properly care for your retainer and how long you should wear it for. Wearing your retainer as directed is crucial to avoiding a relapse in therapy.


Separators are little rubber doughnuts that are put between your teeth to force them apart so that orthodontic bands may be fitted at your next consultation. Before we put the bands, the separators will be removed. Sticky foods, toothpicks, and floss do not allow separators to do their job correctly.


The twin block appliance, unlike other functional appliances, combines two separate appliances (one for the upper arch and one for the lower arch) to obtain an advanced lower jaw position. This patient-friendly equipment is worn at all times, even when eating, and is simply removed for cleaning. Because it is made of smooth acrylic and contains fewer wires, it is also more pleasant than previous jaw-correcting devices.

A wide, attractive grin, good jaw function, an enhanced profile, and a stable and healthy temporomandibular joint are the results of utilizing a twin block appliance.


MARA stands for Mandibular Anterior Repositioning Appliance. It is a non-removable implant that encourages lower jaw growth in order to cure severe overbites and avoid extractions or orthognathic surgery.

To attach the MARA device to the molars, crowns, modified crowns, or bands are employed. Lower attachments are connected to molars. The top attachments are removable, enabling your orthodontist to modify your treatment plan as needed.
