Summary

This study looked at two different methods to widen the upper jaw in adults: one with surgery and one without. About 50 adults took part and were followed for 12 months. Researchers used 3D scans to measure how well each method worked and how stable the results were. The findings may help dentists choose the best approach for each patient.
