Progressive, clear removable alignersย (examples of which areย Invisalign) may be used to gradually move teeth into their final positions. Aligners are generally not used for complex orthodontic cases, such as when extractions, jaw surgery, or palate expansion are necessary. These braces are the most recent type of braces. The braces are hardly noticeable on the teeth and work to gradually move the teeth into their right position without the need for wires or tightening. Like traditional braces, they do require an improvement in the amount of oral hygiene because they have to be removed to eat and one must brush and floss after every meal.
