Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Cross bite correction in mm, assessed by transverse distance in the molar region, after 6 months of rapid maxillary expansion through digital models | — |
Secondary
| Measure | Time frame |
|---|---|
| Cephalometric changes, assessed by radiographs after 6 months of expansion; cephalometric changes assessed by radiographs, after 1 year of expansion; Change in dental tipping angle after 6 months through digital models; Changes in dental tipping angle of the teeth after one year through digital models; diastema amount, evaluated clinically in mm with a digital caliper after expanding and Dehiscence and fenestration score clinically evaluated after 6 months. Pain.;Evaluate the slope of the posterior teeth, external transverse distances, internal transverse distances, length of the dental arch, thickness of the buccal and lingual bone plates and level of the vestibular alveolar bone crest on CBCT. | — |
