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 several months to solidify the expansion and to prevent regression.
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.
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 mix well with sticky foods, toothpicks, or floss.
The twin block appliance is unique from other functional appliances, as it involves two separate appliances (one for the upper arch and one for the lower arch) working together to create an advanced lower jaw position. This patient-friendly appliance is worn full time, including while eating, though it is removable for easy hygiene. It is also more comfortable than other jaw-correcting appliances, as it is made out of smooth acrylic and utilizes fewer wires.
The result of using a twin block appliance is a broad, beautiful smile, proper jaw function, improved profile, and a stable and healthy temporomandibular joint.
