Chicago Invisalign Aligners - Woman with a Smile Invisalign aligners are made of plastic and are very similar to bleaching trays, except that they are solid, much tighter and are custom-made for a better fit to move teeth in the order prescribed by your dentist. Invisalign Aligners are made from a strong medical grade thermoplastic material which is very clear and almost invisible. The aligners are entirely transparent, and as a result it is far more difficult to notice. In fact, some common names for Invisalign are invisible braces, clear braces, removable braces, translucent braces or hidden braces. They are uniquely developed for the Invisalign treatment plan.

These aligners and retainers are made with USP Class VI medical grade, high molecular weight polyurethane resins. Tests have been conducted to verify the biocompatibility of these materials, and show that they pass all appropriate regulatory requirements and are suitable for human use in the mouth.

Unlike fixed metal braces, with Invisalign Aligners you have the option to eat and drink anything you prefer during treatment by simply removing the aligners. You can also remove the aligners to brush and floss as you usually would. It is important to maintain good oral hygiene, and wearing aligners should not be an excuse for not brushing or flossing regularly.

Invisalign aligners are in fact very comfortable to wear. There are no metal brackets or wires that may cause pain. Some orthodontists also refer to them as ‘contact lenses for teeth.’

What is great about Invisalign aligners is that is takes less than a week to get used to wearing it, and your friends and family who are unaware of the treatment will hardly notice that you have the clear plastic trays on your teeth! Although the Invisalign aligners system may look like a simple piece of plastic, it is certainly much more. They fit perfectly with your lifestyle and routine daily interactions.
