Invisalign is a clear orthodontic aligner that does not use the brackets and wires of traditional braces to straighten teeth. It is not appropriate for all orthodontic problems; it works best in cases of minor tooth crowding. The main advantage of Invisalign is that it is almost undetectable while it is being worn.
The main disadvantage of Invisalign is that, since it is a removable appliance, potential loss and patient compliance can be an issue. The aligners can also affect a person’s speech.
Similar devices to Invisalign include Ortho Clear and the Inman Aligner.
