Patients seeking orthodontic treatment often prioritize aesthetics, and aesthetics play a significant role in orthodontic care. Researchers have developed a range of options, such as ceramic or composite braces, lingual orthodontics, and transparent aligners, to meet the growing demand for alternatives to traditional braces. Clear aligner therapy, which consists of a series of transparent dental appliances designed to fit the shape of a patient's teeth, is one such alternative. Clear aligners, like traditional braces, use a progressive force to control tooth movement, but they do so without metal brackets or wires. This review will highlight the increasing popularity of clear aligners by summarizing a few commonly used systems today. It will also discuss the therapeutic outcomes of this approach, including its scope, limitations, effectiveness, and stability. Additionally, the review will evaluate the potential negative effects of clear aligner therapy.
