Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Expected outcome 1: Stability of maxillary expansion on the day of stabilization of the expander screw, 3 months after screw stabilization, immediately after removal of the expander (after 6 months of containment) and 3 months after removal of the expander; verified through intercanine and intermolar distances in gypsum models in each phase through digital caliper; from the observation of a variation at least 5% in the pre and post intervention values.;Expected outcome 2: Mineral density of the palatine suture on the day of stabilization of the expander screw, 3 months after screw stabilization, immediately after removal of the expander (after 6 months of containment) and 3 months after removal of the expander; verified by measuring the optical density in the anterior region of the medial palatine suture in periapical radiographs, obtained by the parallelism technique with positioning; from the observation of a variation at least 5% in the pre and post intervention values. | — |
Secondary
| Measure | Time frame |
|---|---|
| Expected outcome 3: Dimension of the airway after 3 months of removal of the maxillary expander; verified by measuring the volume of the airways by tomography; from the observation of a variation at least 5% in the pre and post intervention values.;Expected outcome 4: Improvement in quality of life after 3 months of removal of the maxillary expander; verified by the Child Perceptions Questionnaire (B-CPQ) for children 8 to 10 years and 11 to 14 years; from the observation of at least 5% in the pre and post intervention values.;Expected outcome 5: Pain sensitivity variation on the day of stabilization of the expander screw, 3 months after screw stabilization, immediately after removal of the expander (after 6 months of containment) and 3 months after removal of the expander; verified through the visual analogue scale (VAS); from the observation of at least 5% in the pre and post intervention values. | — |
