They are made of estetic ceramic composite materials. They are very strong and generally do not stain. At our office, we use the popular brand Clarity made by 3M Unitek. Adults like to choose ceramic clear braces because they "blend in" with the teeth and are less noticeable than metal.
Ceramic Clear braces are suitable for all types of orthodontic problems. The ligatures (tiny rubber bands) that hold the arch wire on to the ceramic brackets are often white or clear. Unless you eat a lot of curry, smoke, or drink a lot of black coffee, staining isn't a problem. Note that the ligatures are changed each time you get an adjustment -- usually, monthly. It's only the ligatures that stain, not the brackets themselves!
They are the most common. They are made of high grade stainless steel. With today's technology, metal braces are made smaller, more comfortable, and are more attractive.
Metal brackets are very strong and can withstand most types of treatment. Most traditional metal braces require an elastic o-shaped rubber band, called a ligature to hold the arch wire onto the bracket. Sometimes we use metal tie wires (little wires which are twisted around the bracket) in place of elastic ligatures.
There are no metal wires and brackets, so Invisalign is comfortable. It's removable, making eating, brushing, and flossing no problem. You can still enjoy your favorite foods.
During your consultation, our orthodontist will decide if Invisalign will work for you. It's hard to tell that you're wearing Invisalign. You will wear each aligner for about two weeks, and you will only take it out for eating, brushing, and flossing. When you replace each aligner with the next in the sequence, your teeth will gradually shift until they move into the final alignment that your orthodontist prescribed.
