There is no study that compared the effect of different protocols. The aim of this study was to assess the effect of Invisalign aligners in four first-premolar extraction treatments in adolescents using three aligner wear protocols, every 7, 10 and 14 days.</p><p><strong>Materials and methods: </strong>In the experimental set-up, 50 participants were divided into three distinct groups: group A, with a regimen of changing aligners every 7 days; group B, with a 10-day interval for aligner replacement; and group C, where aligners were replaced every 14 days. The evaluation of occlusal adjustments was conducted employing the Discrepancy Index (DI) and the Cast-Radiograph Evaluation (CRE), as defined by the American Board of Orthodontics for the purpose of recording orthodontic outcomes.

Initial cephalometric radiographs were used for the diagnosis of malocclusion. The case group was divided into three subgroups according to degree of open bite. For DNA isolation, oral epithelial cells were collected with buccal swabs (Van Allen Way, Carlsbad, USA), and the real-time PCR method was used for the genotyping of all polymorphisms.

There was no statistically significant difference between the groups in terms of the presence of the examined polymorphism (<i>p</i> &gt; 0.05).
