Eligibility

Age
7 Years to 10 Years

Inclusion criteria

Inclusion criteria: Children and adolescents with anteroposterior discrepancy between the maxilla and mandible, caused by maxillary retrusion, mandibular protrusion and/or a combination of both, clinically assessed by facial analysis (nasolabial angle, chin-neck line and angle);children and adolescents with Class III and/or Class III Angle subdivision malocclusion;and children and adolescents with mixed dentition or beginning permanent dentition

Exclusion criteria

Exclusion criteria: Children and adolescents with decayed and periodontally compromised teeth; those who had undergone previous orthodontic treatment; those with a metal device; those who were claustrophobic and/or anxious, making it impossible to perform the MRI scan
