First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study compared two popular clear aligner systems—Invisalign and Angel Aligner—to see how accurately they widen the upper jaw in adults with a narrow palate. Researchers measured the planned versus actual tooth movement in 60 participants using digital models. The goal is to help orthodontists choose the most predictable system for expanding the dental arch.
