Biomechanics of Clear Aligners A Literature Review

Clear aligners, a popular orthodontic treatment modality, leverage biomechanical principles to gradually reposition teeth and correct malocclusions. Constructed from flexible thermoplastic materials, these aligners apply controlled forces to teeth, orchestrating their movement over time. Customized for each patient based on digital impressions, aligners utilize attachments strategically placed on teeth to enhance force application. By employing principles like moment-to-force ratios, clear aligners exert precise forces to address various malocclusions, while stimulating bone remodeling around teeth. Patient compliance is paramount, as consistent wear ensures effective force application and facilitates tissue adaptation. Ultimately, clear aligners harness biomechanics to achieve predictable tooth movement, promoting both functional occlusion and aesthetic outcomes in orthodontic treatment.
