Summary

This study tested a special dental appliance to correct underbite (Class III malocclusion) in 36 children aged 7 to 12. The device combines a fixed inclined plane on the lower front teeth with rotated brackets on the upper front teeth to encourage proper jaw growth. After 6 months, success was measured by improved bite alignment and jaw position using X-rays.
