Comparison of Patient Satisfaction between Invisible Appliance and Fixed Orthodontic Appliances - A Systematic Review.

To compare the patient acceptance between fixed orthodontic appliances and clear aligners. An electronic search was completed in PubMed, Cochrane Database, Web of Science, Scopus, Lilacs, Google Scholar, and Open Grey databases without any restrictions until August 23. All comparative study types contrasting patient perception between clear aligners and fixed appliances were included. After removal of duplicates, exclusion by title and abstract, and reading the full text, only eight articles were included. The studies used an observational questionnaire study design. Of the observational studies, one was retrospective and three prospective, one online survey, and the other three cross sectional. Though the response varied in terms of patient preference and acceptance, it was found that clear aligners have a positive impact with respect to quality of life, tolerance, and improved confidence. However, there is not enough evidence to make a final conclusion about treatment outcomes.
