Dental arches and occlusion correction possibilities with clear aligners

Threatment with thermoplastic aligners is relatively new in the history of orthodontic treatment, that is why many doctors evaluate this treatment method controversially. The aim of this study is to evaluate and better understand the treatment with thermoplastic aligners method effectiveness, for this purpose the systemic review was made. The total sample of 10 scientific articles was chosen for the review, 2 of them tested thermoplastic aligners generated forces during treatment, 4 articles evaluated teeth shift during the treatment with aligners, 2 articles evaluated the accuracy of computer programs used with aligners, 2 articles compared aligners with braces. In this systemic review was found that forces generated during the treatment with clear aligners often exceed recommended orthodontic forces, during the 2-week treatment period teeth shift 0.39 - 0.74mm for overbite and 0.69 - 1.33mm for overjet. The accuracy of computer programs created post- treatment image is from 40 to 100%. Treatment with braces is more effective and lasts less than treatment with clear thermoplastic aligners.
