Effect of upper jaw expansion on lower jaw growth in children
Study the Effect of Upper Expansion Appliances on Lower Jaw Forward Projection/Growth

What this trial studies
This study investigates the impact of upper jaw expansion appliances on the forward growth of the lower jaw in young children aged 9-11 with a backward positioned lower jaw. A total of 60 participants will be recruited to receive either an active or non-active Wilson type upper arch expansion appliance. The effectiveness of the treatment will be assessed using Cone Beam computed tomography before and after a 9-month treatment period. Following the study, participants will continue with routine orthodontic care.
Who should consider this trial
Good fit: Ideal candidates are young children aged 9-11 with Class II skeletal malocclusion due to lower jaw backward projection.
Not a fit: Patients currently undergoing other orthodontic treatments or those with growth problems will not benefit from this study.
Why it matters
Potential benefit: If successful, this approach could improve jaw alignment and overall dental health in children with excessive overbite.
How similar studies have performed: Previous research has indicated that upper jaw expansion can lead to positive outcomes in lower jaw growth, suggesting potential success for this approach.
