Invisalign is the invisible way to straighten teeth without braces. Invisalign uses a series of clear, removable aligners to gradually straighten teeth, without metal or wires. Invisalign uses 3-D computer imaging technology to depict the complete treatment plan from the initial position to the final desired position from which a series of custom-made, clear “aligners” are produced. Each “aligner” moves teeth incrementally and is worn for about two weeks, then replaced by the next in the series until the final position is achieved.
