Design outcomes
Primary
| Measure | Time frame |
|---|---|
| To analyze the expansion of the mandibular and maxillary arches in the canine region using polyethylene terephthalate glycol (PETG) aligners, with different thicknesses (0.50 mm and 0.75 mm), evaluated through intraoral scanning with a 3Shape scanner (3Shape, Copenhagen , Denmark), which will be carried out before treatment (T0) and immediately after the end of treatment (T1), the parameter used will be the increase in intercanine distance in millimeters in pre- and post-intervention measurements. | — |
Secondary
| Measure | Time frame |
|---|---|
| To analyze the expansion of the mandibular and maxillary arches in the region of the premolars and molars, using polyethylene terephthalate glycol (PETG) aligners, with different thicknesses (0.50 mm and 0.75 mm), evaluated through intra-oral scanning with a scanner 3Shape (3Shape, Copenhagen, Denmark), which will be performed before treatment (T0) and immediately after the end of treatment (T1), the parameter used will be the increase in intercanine distance in millimeters in pre- and post-intervention measurements. | — |
