Summary

This study tested a new device called the Leaf Self Expander to widen the upper jaw in 20 children with cleft lip and palate. The device was compared to the standard rapid maxillary expander. Researchers used 3D scans to measure changes in bone and tooth position. The goal was to see if the new device works as well or better before bone graft surgery.

What this could lead to: If successful, this device could offer a more comfortable or effective way to widen the upper jaw in children with cleft lip and palate, improving dental alignment before bone grafting.
