Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Differences in the clinical efficacy of orthodontic aligners made with the two different plastic materials will be evaluated. For this evaluation, tooth movements will be compared after the first set of aligners is completed. Digital models (STL) and Ansys software will be used. Tooth movements will be considered relevant if statistically significant differences are detected for the deviation limit established as 0.5 mm for linear measurements and 2 degrees for angular measurements, considering the worst possible clinical outcome for two contiguous teeth. | — |
