Clear Aligners, A Milestone in Invisible Orthodontics – A Literature Review

The increase in awareness of optimal esthetics and the orthodontic treatment demand from adults has raised the demand for a more enhanced orthodontic treatment technique. Clear aligners are an alternative to conventional orthodontic braces and are manufactured to help guide teeth into their ideal position. Identical to braces, clear aligners use a gradual force for an organized tooth movement, but without metal wires or brackets. The aligners are made of a strong plastic material and are fabricated to fit each individual's mouth. Improved oral hygiene, discrete look, comfort and protection from tooth grinding are some of the major advantages of using the aligners. Clear aligner technology has been improving over the years and can correct many malocclusions that once would have been too complicated for this form of treatment. Continued developments on the technological front are being adapted to improve efficiency of clear aligners, especially in complex cases
