Title : Efficacy of Clear Aligners in Treatment of Non-Extraction Orthodontic Cases: A Clinical Study

Abstract :

As the demand and interest toward the clear aligner system continue to grow, questions regarding the efficacy of the system remain. Nowadays, published data include little clinical research on the effectiveness and efficacy of clear aligners. Previous literature primarily included case reports or descriptions of the product, making it difficult to objectively characterize the efficacy of clear aligner systems. This study aimed to assess the treatment outcomes of clear aligners in non-extraction orthodontic cases. This study was carried out upon 7 patients indicated for non-extraction orthodontic treatment with an age ranging from 20 to 40 years old, selected from the outpatient orthodontic clinic, Faculty of Dentistry, Suez Canal University. The assessment was made by using the American board of orthodontics grading system for measuring alignment/rotation, marginal ridges, bucco-lingual inclination, overjet, occlusal contacts, occlusal relationships, interproximal contacts and root angulation using the ABO measuring gauge, cast and panorama. The resulted data revealed that there was a statistically significant difference between before and after treatment values of alignment/rotation, buccolingual inclination, overjet, interproximal contacts and root angulation of teeth, while there was no significant difference between before and after treatment values in marginal ridges, occlusal contacts and occlusal relationship. Based on the results of this study, it was concluded that: The use of clear aligners for treatment of class I non-extraction orthodontic cases was efficient and had clinically accepted treatment outcomes as mostly, all the measured variables improved after treatment according to the ABO assessment.
