The eligible criteria are posterior cross-bite, mixed dentition, skeletal Class I relationship and prepubertal stage of cervical vertebral maturation. The patients will be split into three groups according to facial divergency (hyper-, hypo-, normodivergent subjects). For each subject, digital dental casts will be recorded before and after treatment using an intraoral scanner. To evaluate two-dimensional maxillary arch changes, linear measurements will be done. To study comprehensively the palatal shape, a set of 240 landmark and semi-landmarks will be digitized on the palatal vault. Then, Geometric Morphometric Analysis (GMA) will be performed to compare morphological variations of the palate among different vertical facial growth pattern groups.",[66,67],"Cross-bite","Malocclusion in Children","2025-08-26",{"date":70,"type":71},"2025-09-03","ACTUAL",{"date":73,"type":71},"2024-07-17",{"date":75,"type":61},"2026-12-31",{"name":5,"class":6},1]
